3 ­ GENERAL DESCRIPTION

3.1 OPERATING TECHNOLOGY
Your appliance has been built to fully satisfy all your heating and practical requirements. Top-grade components and functions managed with microprocessor technology guarantee high reliability and optimal performance.

3.2 THE PELLET
The appliance is fuelled by pellets, that is, cylinders of compressed sawdust; it his allows you to fully enjoy the heat of the flame without having to manually stoke the combustion. The pellets have a 6 mm diameter and a length between 10 e 20 mm. They have a max moisture content of 8%; a thermal value of 4000/4500 Kcal/kg and density of 630-640 kg/m³. It must be approved according to UNI EN 14961-2 A1 A2. It is strictly forbidden to use any pellet type other than that specified above. The use of fuel that does not comply with the above specifications not only immediately invalidates the warranty for the appliance but can also create dangerous situations. Do not use the appliance as an incinerator, at the risk of voiding the warranty.

3.3 PELLET REFUELLING
The feedbox is situated in the top part of the appliance. The load capacity specified in the technical data can vary according to the specific weight of the pellets. Take special care when loading the tank as the screw feeder at its base is in motion. Take care when topping up with fuel as the loading area can get very hot. ATTENTION: it is normal to find some pellets remaining in the tank even if the stove shuts off because the pellets have run out.

Attention: when filling up the tank, take care not to drop any pellets into the internal parts of the appliance, as, in extreme cases, this could generate live flames. The manufacturer recommends emptying the tank and vacuuming the screw feeder zone once a month and during the summer period.
Only pellets complying with the above specifications are to be loaded into the tank; in no case whatsoever must foreign substances or objects be introduced into the tank, the brazier or any part of the generator.

4.1 APPLIANCE LOCATION Follow the general guidelines set out in paragraph 1.1 to the letter. Above all keep in mind that the flooring of the room in which the appliance is being installed must withstand the weight of the stove with the added weight of the pellet load and the water contained in it.

ATTENTION: The room where the appliance is installed must be well-ventilated and free from humidity and salty air. A high level of humidity or saltiness in the room can lead to the onset of rust or corrosion which will not be covered by warranty. If inflammable materials are located in the vicinity of the appliance (e.g.: matchboarding, furniture, curtains, pictures and paintings, sofas) it is mandatory to comply with the minimum distances illustrated (see figure on the side). Installation in the vicinity of heat-sensitive materials is only permitted if suitable insulating and fireproof protection is placed between the object and the appliance (ref. Uni 10683). If the flooring is made of wood or any other combustible material, it is mandatory to install a fireproof floor protector plate between the appliance and the floor. Installation in the vicinity of heat-sensitive materials is only permitted if suitable insulating and fireproof protection is placed between the object and the appliance (ref. Uni 10683). Failure to observe this instruction will immediately invalidate the warranty.

A = 200 mm L = 200 mm P = 200 mm

The installer must issue a certificate of conformity for the installation which includes the design plans and the following documents: a) Report containing the type of materials utilised. b) Project as defined in Article 5 of Ministerial Decree n° 37 22 January 2008. d) References to existing partial or previous declarations of conformity (e.g. electrical wiring). e) Copy of the certificate of recognition of the professional technical qualifications.

These documents must, by law, be kept together with the use and maintenance booklet. The customer is responsible for verifying, directly or indirectly, that the installation has been carried out to perfection in accordance with relevant regulations in force. Do not install the appliance in unsuitable rooms such as bedrooms, bathrooms, garages and/or lock-ups. It is forbidden to place the appliance in environments with an explosive atmosphere.
ATTENTION, the appliance is not simply a household appliance: if the instructions set out in this booklet are not followed and/or if installation of the appliance is not executed perfectly and/or the provisions in force are not strictly complied with, dangerous conditions could arise for both objects and persons. It is the user’s responsibility to verify the presence, in the room, of a vent necessary for supplying oxygen to the generator.
The installer must provide the final user with verbal instructions on the correct use of the appliance when the appliance is set at work for the first time.

Over 61°C, the generator circulating pump is always active as the heat must be dispersed; consequently, the solenoid valve in the zone with the greatest absorption must be opened for the following reasons: · to prevent the generator from continually starting up and shutting off caused by the inevitable loss of heat to the header and/or due to system tubing. · to prevent the generator from raising the water temperature by just a few degrees each time it is switched off then back on until it shuts down due to exceeding the maximum threshold temperature. To adjust the ambient temperature in which the valve opened, we recommend connecting the room temperature thermostat to the MODEM terminal that allows the machine to be shut off via an external contact and therefore also restarted. This ensures that the generator only activates if there is a real request for heat from the zone in which the chronothermostat is installed. Several parallel-connected room temperature thermostats can be installed in the MODEM terminal. This will ensure that the zone requesting heat automatically activates the generator. In the event of frequent startups and shut offs due to the heat produced by the generator not being absorbed, the manual reset safety thermostat trips and blocks the generator.
N.B. Use chronothermostats having at least 2°C hysterisis.
The system must always be capable of absorbing all the power that the generator is capable of delivering. If you do not observe this requirement , the generator could be subjected to numerous stops and starts. It is recommended not to exceed three lighting cycles per day.

ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which is not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the earthing. There must be no electric potential (Volt) between the generator earth and the system’s real earth (earth plate). To prevent electrochemical corrosion of the appliance body do not use galvanised pipes and
fittings. Other materials must be earthed with special earthing cables in order to obtain a unipotential earthing system.

ATTENTION: The water temperature in the boiler tubes in this case is not adjustable and depends on the system’s delivery temperature, that is the temperature set in the generator. The boiler tubes can be installed on the water return circuit. It is recommended to install a water softener in the domestic water system in order to maintain the boiler at its peak efficiency.
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which is not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the earthing. There must be no electric potential (Volt) between the generator earth and the system’s real earth (earth plate). To prevent electrochemical corrosion of the appliance body do not use galvanised pipes and fittings. Other materials must be earthed with special earthing cables in order to obtain a unipotential earthing system.

In order to guarantee correct absorption of the heat produced by the generator it is advisable to use a boiler tube with volume and heat exchange capacity suitable for the power of the generator. The boiler tube must have a minimum capacity of 300l. In any case the boiler tube must be capable of absorbing all the power that the generator is capable of delivering. If this rule is not observed, the generator could raise the water temperature to such a point as to activate the safety limit thermostat which stops the fuel from dropping into the burner and therefore forces the appliance to shut off. The installer is required to install a valve that switches over to the system, powered by the appliance’s control unit, which trips when the boiler tube is thermally “satisfied “. Consequently, the system must be designed in such a way that the hot water produced by the generator can reach the various rooms by acting on the zone valves.
ATTENTION: it is mandatory to earth the generator. If this instruction is not observed serious damage, which
is not covered by warranty, will result to the body of the appliance. Have a skilled electrician check the
earthing. There must be no electric potential (Volt) between the generator earth and the system’s real earth (earth plate). To prevent electrochemical corrosion of the appliance body do not use galvanised pipes and
fittings. Other materials must be earthed with special earthing cables in order to obtain a unipotential
earthing system.

5.7 INSTRUCTIONS FOR EXECUTING THE HYDRAULIC SYSTEM CLOSED EXPANSION TANK
To install the system with a closed expansion tank refer to the requirements laid down in EN 10412-2:2009 for appliances with nominal heat output not exceeding 35 kW or in the Ministerial Decree Collection R edition 2009 for appliances with nominal heat output exceeding 35kW.
The hydraulic system must be installed by qualified personnel who are familiar with the standards mentioned above and who have the appropriate professional requirements to release the declaration of conformance in accordance with Ministerial Decree n° 37 of 22 January 2008.
The generator is already supplied with the following safety devices on board:
a) closed expansion tank for generator protection only* b) ordinary safety valve 3 bar, not I.S.P.E.S.L. approved c) an automatic reset temperature limiting device; This is an automatic adjustment device that interrupts the fuel supply to the generator when the water reaches the temperature setting. The system starts up again automatically when the water temperature drops below the preset value. d) a manual reset temperature limiting safety device; This is an automatic device that interrupts the fuel supply when the water reaches the maximum permissible temperature. The fuel infeed will only restart when the water temperature drops below a preset value and after the device has been reset manually. e) circulation system. The appliance is fitted with a circulating pump connected to the return pipes which is controlled directly by the generator’s control board.

• An additional closed expansion tank must be series-connected to the generator as protection for the system. The nominal volume of the additional closed expansion tank must be sized in relation to the volume of expansion of the water contained in the system. Thermorossi prescribes that the size of the additional closed expansion tank must be equal to 10% of the water contained in the system.
  The previous chapter does not replace the above standards to which it makes reference. The qualified installer must in any case be fully aware of the above standards and their amending versions.

7) To conclude the programming operations simply press the Menu Button several times to exit the box until the initial screen will appear.
ATTENTION: The appliance ignores any ON or OFF command programmed with a value of 00:00. Consequently if you do not wish to use an ON or OFF time setting simply set a value of 00:00. The appliance ignores any ON or OFF command if the shut off time is set the same as or before the start up time.
ATTENTION: In the event of a programmed cycle on always ensure that the brazier is clean. Failure to clean the brazier can reduce and/or affect the life of the spark plug as it would be subjected to high temperatures due to poor cooling. It is recommended to set ON/OFF cycles times lasting no less than 2 hours, in order to save energy and for the proper operation of the appliance.
Enabling the programmed cycles:
Back in the initial screen, to enable the appliance to carry out the ON/OFF cycles as programmed it is necessary to press the Clock Button. The image of a clock will appear on the main screen:

The programmed cycles are now enabled.
When the programmed cycles are enabled (a clock symbol appears on the display) it will not be possible to use an additional chronothermostat (see dedicated paragraph). The appliance will strictly follow the programmed ON/OFF times. No request for heat by the system, a puffer or a domestic hot water boiler will be considered by the appliance if it is outside the programmed time interval.
Disabling the programmed cycles:
To disable the appliance from carrying out the programmed ON/OFF cycles press the Clock Button once again. On the display the clock symbol will disappear. This operation disables the weekly program that has been set by the user but does not delete or reset the times.
Resetting the programmed cycles: Moreover, it is possible to reset, in other words delete, all the programmed cycles entered by the user by holding down the Clock Button in the initial screen for approx. five seconds. The words CLEAR TIMERS will appear momentarily on the screen.
Do not release the button until the text CLEARED appears on the screen. Only the appearance of the words CLEARED signal that the previously entered programmed cycles have been deleted. When the programmed cycles are active the operating level at start up, that is the combustion power, will be the same level set before the last time the machine was shut off: that is, only if it was a programmed shut off, not if the machine was shut off by means of a manual action. Manual shut down can only be carried out with the programming disabled. If after a manual shut off the programmed cycle re-enables, at the next programmed start up the appliance will be on the 1st combustion power level.

Page 23

Installation, use and maintenance guide COMPACT S18 EVO
When is it important to use the CHRONO function?
In systems configured like the diagram on the right, where the appliance is connected directly to the system, without the use of external chronothermostats. In this case it is necessary to set the hour programs to prevent the appliance from being stressed by uncontrolled ON and OFF cycles. In addition we recommend using the generator in AUTO mode to activate the automatic modulation based on the target temperature setting. If the dwelling is fitted with zone valves, with this type of installation, it is mandatory to deactivate the valves by opening them completely. Consequently the dissipation of heat, at least equal to or greater than the quantity of heat generated by the appliance and transmitted to the water when running at the minimum power level must be guaranteed at all times.

ENG

6.5 LEVEL: OPERATING LEVEL SETTING The appliance must be energised and the I/0 switch in position “I”. Your appliance is delivered with an excellent program installed that favours combustion efficiency; the program is called LEVEL 1.

However, if you are using pellets with a higher than normal incidence of residues after combustion in the brazier, it is possible to

select alternative levels:

LEVEL 2

is an operating program that accelerates the speed of the smoke suction unit in proportion to all the combustion

power levels. This level must be set when the user notices a weak, high and very dark flame. Attention: this

modification does not authorise the use of below-standard pellets, or no vacuum in the flue outlet.

If using loosely compressed pellets, you could select:

LEVEL 0:

is an operating program that decelerates the speed of the smoke suction unit when using loosely compressed

pellets and/or when the flue outlet has a very high vacuum, over 2 mm water column (20 Pascal).

The pellet consumption value remains unchanged regardless of the selected operating level. These variations will only change the rotation of the smoke suction unit in the WORK stage (see para. 6.10), all the other stages will not undergo any changes.

Select the required Level by acting as follows:

1. Press the Menu Button three times quickly and the following box will appear:

After a few seconds the following screen will appear on the display:

2. To change the operating level, hold down a Scroll Button while simultaneously pressing the other Scroll Button.
   To set the desired level simply press the Menu Button several times until the initial screen will appear on the display.
   The level selection can be made with the appliance OFF or ON. If the change is made while the appliance is running the difference in the flame will be apparent. It is mandatory to pay particular care when selecting the most appropriate operating cycle for your installation. After the selection of the operating cycle a thorough cleaning of the brazier is mandatory.
   6.6 THERMOCONTROL: CONTROLLING A PUFFER The appliance must be energised and the I/0 switch in position “I”. This function enables you to control the operating temperature of a stratification puffer through the use of two sensors PT 100 (optional) connected to the respective terminal block on the electronic board (see para. 11). ATTENTION: If one or both optional sensors are not connected to the appliance or are interrupted, it will not be possible to view and therefore activate the THERMOCONTROL function. When this function is activated the appliance automatically controls the ON/OFF cycles based on the activation temperatures set by the user.
   The puffer must have an appropriate capacity. We recommend a capacity ranging between a minimum of 20 dm3 to a maximum of 50 dm3 for every kW of maximum power supplied to the water by the appliance.
   The THERMOCONTROL function can be activated in the following way: 1) Quickly press the Menu Button until the following screen appears:

Page 24

ENG

Installation, use and maintenance guide COMPACT S18 EVO

After a few seconds the following screen will appear on the display:

2. Press one of the two Scroll Buttons and the following screen will appear (Select ON to activate).

3. Confirm the selection by pressing the Degrees Button and the following screen will appear:

4. Press the Scroll Buttons to set the activation temperature for Sensor S2. Sensor S2 is installed in the top part of the puffer and it commands the appliance to start up as it is exhausting the available heat inside it. The setting range is between 40 °C and 65 °C.

5. Confirm the selection by pressing the Degrees Button and the following screen will appear.

6. Press the Scroll Buttons to set the activation temperature for Sensor S1. Sensor S1 is installed in the lower part of the puffer and it commands the appliance to shut off as the puffer is satisfied. The setting range is between 60 °C and 70 °C. The settable temperature will in any case always exceed, by at least 4°C,the temperature setting for S2.

7. Confirm the selection by pressing the Degrees Button then press the Menu Buttonseveral times to exit the screen, until the initial screen appears.
   At this point the appliance operating status will appear on the display.
   To disable the THERMOCONTROL function simply repeat operations 1 and 2, but this time select the OFF command. The function will be disabled immediately.
   ATTENTION: it is advisable to set the action temperature for sensors S1 and S2 as indicated in the hydraulic diagrams in this manual. Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this function. It is recommended not to exceed three ON/OFF cycles. If the startups are frequent and repeated it is possible that the the generator will fail to start and the following error message appear: “Failed start ­ Clean burner”. The appearance of this message is not attributable to a product defect but is caused by a brazier that requires cleaning as described in this manual in chapter entitled: “Troubleshooting ­ Possible Causes ­ Solutions”.
   ATTENTION: By setting the THERMOCONTROL ON the appliance will only start up and shut off autonomously according to the temperature settings of sensors S1 and S2.
   ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will follow exclusively the preset ON and OFF times. No request for heat from the puffer will be considered by the appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display.
   ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No request for heat from the puffer will be considered by the appliance if the external chronothermostat does not give consent and the text WAIT TIME appears on the display.
   By setting THERMOCONTROL ON, when the puffer is requesting heat the temperatures detected by the sensors S1 and S2 and the word PUF will appear on the display.
   When is it important to use the THERMOCONTROL function?
   In systems configured like the diagram on the right, where the appliance is connected directly to a stratification puffer. When you use this function the generator starts up automatically when the puffer is running out of heat then switches off when it is satisfied. The use of a correctly-sized puffer also enables the production of low temperature heat, such as for example for under floor heating systems, which otherwise could not be controlled by a high temperature biomass appliance.

6.7 ACS SUMMER: ACTIVATION OF THE BOILER TUBE CONTROL FROM A CHRONO COMMAND
The appliance must be energised and the I/0 switch in position “I”.

ENG

This function enables you to manage the operating temperature of a boiler tube for the production of domestic hot water (ACS) through the use of a sensor PT 100 (optional) connected to the terminal block on the electronic board.

ATTENTION: If the optional sensor is not connected to the appliance or is interrupted, it will not be possible to view and therefore activate this function.

When this function is activated the appliance automatically controls the ON/OFF cycles based on the set temperature of the boiler tube, and ignores requests for heat from the system and the puffer, if installed. This function is particularly useful in summer when only domestic hot water is required without having to supply the heating system. When this function is activated the appliance operates only at automatic power.

The ACS SUMMER function can be activated in the following way: 1) Quickly press the Menu Button until the following screen appears:

After a few seconds the following screen will appear on the display:

ATTENTION The boiler tube must have at least a 300 litre capacity. Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this function. It is recommended not to exceed three ON/OFF cycles.
ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will follow exclusively the preset ON and OFF times. No request for heat from the boiler tube will be considered by the appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display.
ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No request for heat from the puffer will be considered by the appliance if the external chronothermostat does not give consent and the text WAIT TIME appears on the display.
ATTENTION: When ACS SUMMER is set the appliance will start up and shut off autonomously and only according to the temperature setting of the boiler tube and the actual temperature detected.

When is it important to use the ACS SUMMER function?
In systems configured like the nearby diagram, where the appliance is connected directly to a domestic hot water boiler tube and to the system. Using this function the generator starts up automatically when the boiler tube is running out of heat and only in the programmed time bands. Once the boiler tube is satisfied, the appliance does not supply heat to the system and shuts OFF.
6.8 T.AMBIENT: CONTROLLING THE ROOM TEMPERATURE The appliance must be energised and the I/0 switch in position “I”. This function enables you to control, through the use of a sensor PT 100 (optional) to be connected to pins 1 and 2 of the terminal block CN5 on the electronic board (see para. 11), the temperature of the room where the sensor will be placed. ATTENTION: If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to view and consequently activate the T.AMBIENT function. When this function is activated the appliance will automatically control the ON/OFF cycles according to the temperature set by the user.
The TAMBIENT function can be activated by proceeding as follows: 1) Quickly press the Menu Button until the following screen appears:

After a few seconds the following screen will appear on the display:

2. Press one of the two Scroll Buttons and the following screen will appear (Select ON to activate).

3. Press the Menu Button several times, to confirm and exit the screen, until the initial screen appears.
   When TAMBIENT ON is activated, a house symbol with the temperature detected by the sensor next to it will appear on the display as well as, in the bottom right corner, a thermometer symbol with the target room temperature next to it, as illustrated here:

The target room temperature can be changed at any time from the initial screen by simply pressing the Scroll Buttons.
To deactivate the TAMBIENT function simply repeat operations 1 and 2 in this paragraph, but this time select the OFF command. The function will be disabled immediately.
ATTENTION: If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to activate this function.

Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this function. It is recommended not to exceed three ON/OFF cycles. If the startups are frequent and repeated it is possible that the generator will fail to start and the following error message appear: “Failed start ­ Clean burner”. The appearance of this message is not attributable to a product defect but is caused by a brazier that requires cleaning as described in this manual in chapter entitled: “Troubleshooting ­ Possible Causes ­ Solutions”.

ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will follow exclusively the preset ON and OFF times. No request for heat from the room will be considered by the appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display.

ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No request for heat from the room will be considered by the appliance if the external chronothermostat does not give consent and the text WAIT TIME appears on the display.

ATTENTION: The appliance controls the room temperature sensor with a 2°C hysteresis, so if for example the user sets a target temperature of 22°C when it reaches this temperature the appliance takes its power to the minimum, then switches off when the temperature reaches 24°C. It will only restart when the temperature drops below 20°C at the power previously set by the user. ATTENTION: Do not place the room temperature sensor near any heat or cooling sources that could at any time affect the temperature detected by the sensor.

When is it important to use the TAMBIENT function? In systems configured like the nearby diagram, where the appliance is connected directly to the system. In this case the room temperature sensor controls the activation of the ON/OFF cycle for the appliance according to the set temperature. If the dwelling is fitted with zone valves, with this type of installation, it is mandatory to deactivate the valves by opening them completely. Consequently the dissipation of heat, at least equal to or greater than the minimum power output to the water in the appliance, must be guaranteed at all times.
6.9 THERMO ACS: CONTROLLING A CONFIGURED BOILER TUBE IN A SYSTEM The appliance must be energised and the main switch in position [I] . This function enables control of the operating temperature of a boiler tube for the production of domestic hot water (ACS) through the use of a sensor PT 100 (optional) connected to the appropriate terminal block (see para. 11). When this function is activated the appliance automatically controls the diverting valve to give priority to the domestic hot water. Once the boiler tube is satisfied, the appliance switches the diverting valve to the system or the puffer (if installed) if they require heat.
ATTENTION: If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to view and consequently activate the THERMO ACS function. The THERMO ACS function can be activated by proceeding as follows:

1. Quickly press the Menu Button until the following screen appears:
   After a few seconds the following screen will appear on the display:

2. Press one of the two Scroll Buttons and the following screen will appear (Select ON to activate).

3. Confirm the selection by pressing the Degrees Button and the following screen will appear:

4. Press the Scroll Buttons to set the minimum activation temperature for the sensor. The sensor is installed in the central part of the boiler tube and commands the appliance to start the boiler if it is off. On the other hand if the appliance is operating, it commands the diverting valve as the available heat inside it is coming to an end. The setting range is from 45°C to 65°C.

Page 28

ENG

Installation, use and maintenance guide COMPACT S18 EVO

5. Confirm the selection by pressing the Degrees Button and the following screen will appear.

6. Press the Scroll Buttons to set the maximum activation temperature for the sensor. The sensor commands the appliance to shut off if it is ON, whereas if the appliance is operating, it commands the diverting valve as the boiler tube is satisfied. The setting range is from 49°C to 75°C. Attention: The maximum temperature will always exceed, by at least 4°C, the minimum set temperature.

7. Confirm the selection by pressing the Degrees Button followed by the Menu Button.
   At this point the appliance operating status will appear on the display.
   To disable the THERMO ACS unction simply repeat operations 1 and 2 selecting the OFF command. The function will be disabled immediately.
   When this function is activated the appliance operates at the automatic power (see para. 6.10.3) when the domestic hot water boiler tube is requesting heat, it then reverts back to the power selected by the user when the boiler is satisfied.
   ATTENTION: The boiler tube must have at least a 300 litre capacity. If the optional sensor is not connected to the appliance or if it is interrupted, it will not be possible to activate this function. Pay special attention to the number of ON/OFF cycles that the appliance is subjected to with this function. It is recommended not to exceed three ON/OFF cycles. If the startups are frequent and repeated it is possible that the the generator will fail to start and the following error message appear: “Failed start ­ Clean burner” (see para. 10). The appearance of this message is not attributable to a product defect but is caused by a brazier that requires cleaning as described in this manual in chapter entitled: “Troubleshooting ­ Possible Causes ­ Solutions”.
   ATTENTION: If the programmed time schedule is enabled (a clock symbol appears on the display) the appliance will follow exclusively the preset ON and OFF times. No request for heat from the boiler or system will be considered by the appliance outside the programmed time interval and the texts WAIT TIME or NO PROGRAM will appear on the display (see para. 6.10).

ATTENTION: If an external chronothermostat is connected to the appliance, the appliance will follow it exclusively. No request for heat from the boiler tube or system will be considered by the appliance appliance if the external chronothermostat does not give consent and the text WAIT TIME appears on the display (see para. 6.10).
When ACS ON is activated the shower symbol with the temperature detected by the sensor will appear on the display. The shower symbol will flash if the boiler tube requesting heat, whereas it will remain steady if the boiler tube is satisfied.
When is it important to use the THERMO ACS function?
In systems configured like the nearby diagram, where the appliance is connected directly to a domestic hot water boiler tube and to the system. When using this function the generator starts up automatically when the boiler tube is running out of heat. Once the boiler tube is satisfied, the appliance switches the 3way valve to provide heat to the system. We recommend installing a chronothermostat to prevent the appliance from being stressed by uncontrolled ON and OFF cycles (see para. 7.2)
When is it important to use the THERMO ACS function together with the THERMOCONTROL function?
In systems configured like the nearby diagram, where the appliance is installed in a system fitted with both a boiler tube and a puffer. Activate the THERMOCONTROL function to control the puffer and the THERMO ACS function to control the boiler tube. With this logic the appliance controls the ON/OFF cycles automatically according to the heat requests from both the puffer and the boiler tube. Precedence is always given to the boiler tube, and once satisfied, the appliance switches the 3-way valve and diverts the heat to the puffer and when it is satisfied it switches OFF.

6.10 OPERATION OF THE GENERATOR

6.10.1 DESCRIPTION OF THE OPERATING STAGES

Temperatura acqua generatore (°c)

START: has a duration of approx. 20 minutes, during this phase the

appliance is programmed to light the flame. The appliance will not

accept power variations in the firebox. If the appliance does not start

up correctly it could be due to one of the following factors:

cleanliness of the generator, smoke exhaust particularly cold, sudden

surges and drops in the electric power supply, fuel is too moist or

does not comply with the specifications (see para. 3.2).

pellet embers in the brazier die out. A few seconds aftet the activation of the OFF cycle the brazier cleaning mechanism “Pellet

Power”, that is, the device installed inside the brazier, moves in continuous mode. After approx. 25 minutes the appliance goes to

standby and the brazier cleaning mechanism “Pellet Power” stops.

ATTENTION: It is recommended to verify at least once a month that when the appliance is in OFF mode in the time interval specified above, the brazier cleaning mechanism “Pellet Power” operates in continuous mode to clean the brazier.
STOP: If the temperature of the appliance exceeds the 80°C threshold, the momentary shut off, identified as STOP, is activated. ATTENTION: The STOP phase allows the generator to begin a new START phase only when the temperature drops below 58°C. ATTENTION: The STOP mode must be considered an overtemperature pre-allarm, and therefore cannot be considered a normal operating stage.
WAIT ON: when the appliance is restarted while hot where the water temperature is higher than 63°C the appliance does not start immediately, but the circulating pump will still be active. The message WAIT ON appears on the display. A new startup procedure will not begin until the temperature drops to 58°C. The text START will appear on the screen.
SUN OUT: this function only activates automatically if the THERMOCONTROL function is turned to ON and if solar panels are connected to the puffer. When Sensor S2 detects a temperature over 80°C and the appliance is in OFF mode, the text SUNOUT will appear on the display accompanied by the circulating pump active indicator and activation of the smoke suction unit at the maximum power. When the temperature of sensor S2 drops below 75°C, the SUNOUT text deactivates and OFF appears in its place; the circulating pump and the smoke suction unit switch off. This guarantees the dissipation of the excess heat from the solar panels, a situation that could easily arise on the Summer days.
WAIT TIME: The Chrono programming has been activated and the appliance is waiting for the first scheduled ON cycle to activate itself; it is similar to the OFF cycle except that in this function the appliance waits for the time programmed by the user to reactivate.
NO PROGRAM: The Chrono programming has been activated by pressing the clock button, but no valid programming was made.

6.10.2 SETTING RANGE Heat transfer occurs according to the anticondensation principle, that is by activating the circulating pump at 61°C. Activating the circulating pump at a lower temperature could lead to the formation of acid condensation which is extremely harmful for the components of the appliance and seriously affect their duration.

6.10.3 AUTOMATIC CYCLE In the automatic cycle the appliance expresses its maximum operating flexibility by optimising the fuel consumption. To activate the AUTO cycle, select the power bars up to the sixth bar containing the text AUTO. During the AUTO cycle the appliance self-regulates the combustion function according to the temperature of the water in the boiler set with the Degrees Button. The setting range is between 65°C and 73°C.
ATTENTION: We recommend against activating the Auto function if the THERMOCONTROL function is active in the appliance.

Example: If for example the temperature is set at 70°C the five speed levels will be automatically distributed between 61°C and 70°C so that with a temperature set at 70°C the appliance is at its minimum power level.
If the temperature value is increased or reduced all the power levels will be redistributed along the new temperature range. We therefore recommend finding the correct temperature in order to optimise the full potential of the produced heat.. If the value is set at a high temperature, let’s say 73°C, the appliance will attempt to reach that level as quickly as possible by modulating the power as it approaches the set temperature. It is not necessary to set high t max temperatures when the ambient conditions do not require them. Time and experience in using the appliance will give you the possibility of determining which are the most appropriate SET POINTS for your needs. If the combustion power is not absorbed by the system above a temperature of 80° C the appliance will temporarily shut down and the word STOP will appear in the display. Reactivation will occur automatically when the temperature drops to 58°C.

The manual cycle is indicated on the display by the power bars. The power expressed in this cycle remains always constant independently from the power absorbed by the system. As always, the system’s circulating pump is activated at the anticondensation temperature, that is above 61°C. In the manual operating mode the power remains as set until the maximum temperature of 80°C is achieved, then the generator temporarily shuts off and displays the word STOP. Reactivation will occur automatically when the temperature drops to 58°C.

6.11 SWITCHING ON THE APPLIANCE

Before using the appliance check that all the movable parts are correctly fitted. Also remove any labels and stickers from the glass to avoid that permanent traces remain on the surfaces. Verify that the electric and hydraulic connections have been made perfectly. Check also (during all the operating phases) that the firebox door is always firmly closed.

Then carry out the following operations: · Check that the hydraulic system has been correctly executed and has an adequate expansion tank to guarantee maximum safety. The expansion must be calculated as specified in UNI 10412/2. Any damage to the system and/or appliance will not be covered by warranty. The presence of an expansion tank in the appliance guarantees protection against the thermal expansion of the water only in the boiler NOT the whole system.
· Fill the system using the inlet tap. · Power up the appliance and turn the switch installed at the back to position “1” (= ON). · During the replenish stage it is recommended not to overdo the pressure in the appliance: max pressure 1.5 bar. · The water fill phase must be simultaneous with the air purge. · Connect the smoke exhaust to the appliance: we recommend against using aluminium tubes and we recommend always using sealing gaskets. Further information is given in paragraph dedicated to the smoke discharge of this use and maintenance booklet.
· Load the pellets into the hopper. · Press the Flame Button to begin the start up phase and the word START will appear on the display. · Check the pressure in the appliance system once again and if necessary bleed any air bubbles from the valve.

Press the Flame button repeatedly to set the appliance in AUTO or manual operating mode. The mode will be activated at the end of the start up phase. By pressing the Degrees Button you can regulate the desired water temperature in the boiler. During the 20 minutes of the start up
phase any set thermal power level is ignored to deal with correct fill up and suction values preset by the Manufacturer. The electrical heater will start to overheat and only after a few minutes the first lot of pellets will start dropping into the brazier. This occurs because the screw feeder has to fill up because it is completely empty. At the first start up the appliance may require the starting sequence to be performed twice for the reason explained above: before starting up the second time empty and vacuum out the brazier.

ATTENTION: The start up phase (word START appearing on the display) takes approx. 20 minutes during which the appliance ignores any commands transmitted to it. Once this phase has ended the word WORK appears on the display. When the machine is in the running phase the combustion can be adjusted manually or in AUTO mode.

ATTENTION: The system circulating pump only activates when the temperature in the boiler reaches 61°C. ATTENTION: If the appliance does not start up correctly check that the brazier and electric heater are clean. It is very important to ensure that the tube lodging of the electric heater is clean; there must be no deposits or dust. It is recommended to use an efficient ash vacuum cleaner but only when the appliance has cooled down.
6.12 SWITCHING OFF THE APPLIANCE
To switch off the appliance press the Flame Button until the power bars on the display disappear and the text OFF appears.

DO NOT disconnect the generator from the electric power socket to switch it off. This operation generates smoke that could not be evacuated because of the construction characteristics of the flue outlet. The OFF procedure lasts for approx. 25 minutes.

7 ADDITIONAL ROOM TEMPERATURE THERMOSTAT / ADDITIONAL

CHRONOTHERMOSTAT

Your appliance is already fitted with all the temperature adjustment and programming functions. However, the appliance can be connected to an additional room temperature thermostat or to an additional chronothermostat:
– Additional room temperature thermostat: connect the terminals directly to the terminal block on the circuit board, as illustrated in the image below.
– Additional Chronothermostat – Modem: connect the terminals directly to the terminal block on the circuit board, as illustrated in the image below.

The contacts of the room temperature thermostat and of the chronothermostat modem, are defined as “potential free” contacts and they must never be supplied with 230V. If the board is powered with 230 V or lower voltages, the control board would be irreparably damaged and the warranty voided. When the external room temperature thermostat or the external room temperature chronothermostat, connected to the terminal block of the Chronothermostat Modem, activate they start up the generator and the text EXT appears on the display.
This operation must be exclusively performed by qualified professional staff, as set forth by Decree no. 37 of 22nd January 2008 and applicable laws on the subject. Before performing said task, make sure the power supply cable is disconnected from the electrical power socket.

7.1 OPERATING WITH THE ADDITIONAL ROOM TEMPERATURE THERMOSTAT (NOT SUPPLIED) An additional room temperature thermostat can be installed by connecting it to the inside of the electronic board compartment, using contacts 7 and 8 on terminal block CN7 as illustrated in the figure below. It has a “potential free” contact, that is a very low voltage contact. The operating principle is as follows:
· When the room temperature reaches the set temperature, the room thermostat closes the contact, the appliance will operate at the minimum combustion power and the 1st power bar will flash on the display, any manual power change will be disabled. · When the room temperature drops the thermostat opens the contact and the appliance returns to its original position in terms of thermal power.
ATTENTION: N.C. “Normally Closed” contacts must be used for the connection to the additional room temperature thermostat. Do not power the contacts with mains voltage as this would seriously damage the control board, and is not covered by warranty.
7.2 OPERATING WITH THE ADDITIONAL CHRONOTHERMOSTAT (NOT SUPPLIED) An additional chronothermostat can be installed by connecting it to the inside of the electronic board compartment, using contacts 9 and 10 on terminal block CN7 as illustrated in the figure below. Using this output when the chronothermostat contact closes the START cycle begins, whereas when the contact opens the OFF cycle begins. When the chronothermostat is active the appliance cannot be switched off manually but only from the additional chronothermostat.
ATTENTION: The manufacturer denies all responsibility for the life of the electrical heater if subjected to excessive start up cycles. Consequently, it is advisable to set the chronothermostat appropriately. If an external chronothermostat is connected to the appliance it will not be possible to use the Chrono function on the panel.
ATTENTION: Use N.O. (normally open) contacts for the connection to the chronothermostat. Do not supply direct power of 230 V or lower voltages as this would seriously damage the control board, and is not covered by warranty.
ATTENTION: In the event of connections to the chronothermostat Thermorossi shall not be held responsible for the appliance not starting up, smoke leaks, breakage of the lighting component. The user must make sure that the brazier is always clean.
ATTENTION: When using the chronothermostat program up to a maximum of 3 on-off cycles. The chronothermostat must have a thermal hysteresis that is not less than 2°C.

When is it important to use a CHRONOTHERMOSTAT?
In systems configured like the nearby diagram, where the appliance is connected directly to the system. In this case the chronothermostat controls the ON/OFF cycles of the appliance according to the programmed time bands or the temperature setting. If the dwelling is fitted with zone valves, with this type of installation, it is mandatory to deactivate the valves by opening them completely. Consequently the dissipation of heat, at least equal to or greater than the minimum power output to the water in the appliance, must be guaranteed at all times. The chronothermostat must have a thermal hysteresis that is not less than 2°C.

8 – CLEANING AND MAINTENANCE

8.1 FOREWORD
Before beginning any maintenance operation ensure that the appliance is switched OFF and disconnected from the electric power socket. Your appliance, being a pellet-fuelled appliance, requires regular general controls and cleaning. This will guarantee regular operation and optimal output at all times. If the product is unused for a prolonged period of time before starting up it is mandatory to inspect the smoke channel and outlet to ensure that there are no obstructions. It is important to carefully follow the instructions set out below: failure to observe these instructions could cause serious damage to the product, to the system, to objects and to persons using the generator.

Attention: do not wet the appliance and do not touch the electrical parts with wet hands. Never vacuum hot ash: this could damage the vacuum device. All the cleaning operations described in this manual must be carried out when the appliance is cold.

The user must periodically clean the appliance, or have an authorised service centre clean it, as described in this manual. Moreover, once a year it is advisable to have an inspection carried out of the hydraulic system and the functionality of the flue outlet.

8.2 CLEANING AND MAINTENANCE
Due to the frequent cases we have encountered of the use of poor quality pellets, users are advised that it is mandatory to use, in this appliance, pellets certified in accordance with the regulations in force for the Italy UNI market or for the European EN market. If this requirement is not observed the result will be unsuitable combustion, consequently, the electrical and electronic components could be subjected to very high temperatures and will not be covered by warranty.
Unless otherwise instructed, the operations described below are mandatory and not postponable beyond the specified times.

EVERY DAY: ·Thoroughly clean the burner (Figure 1) with a vacuum cleaner; carefully clean the area around the spark plug. This is to ens ure that the appliance operates correctly and to avoid start up failures. · Lift the top cover and move the tube scraper lever up and down vigorously at least 4/5 times (Figure 2).
EVERY WEEK: ·Open the firebox door and check that the area where the Pelletpower® scraper works is sediment-free (Figure 1) ·Check that the holes of the burner and the heater lodging channel is completely sediment-free. If necessary vacuum and clean (Figure 1) ·Remove, if present, all silica agglomerates; they indicate poor quality fuel. ·Empty the ash from the pan C1 (Figure 3) · Lift the inspection cover and thoroughly vacuum the inspection compartment C2 (Figure 4), then make sure that the cover closes perfectly. ·Vacuum the ash from the compartment C3 (Figure 5). Unscrew the two knobs R to access the compartment and remove the cover and the gasket S. When replacing the inspection cover check the condition of the gasket S. If necessary replace the gasket.
EVERY MONTH: ·Inspect and clean the Tee-joint of the smoke exhaust pipe. ·Vacuum, when empty, the saw dust on the bottom of the pellet tank. ·Check that the smoke exhaust pipe is free from any ash deposits, above all in the initial parts that could have a smaller section.
EVERY TWO MONTHS: ·Vacuum the ash in the top compartment C4 (Figure 6). To access the compartment remove the top cover (A) by pulling it upwards. Remove the protection blade (B) as well. Unscrew the 4 wing nuts (D) and the knob. Remove the cover (C) making sure you do not damage its insulation.
Attention: take special care when handling the cover and avoid knocking or dropping it. Accidental breakages are not covered by warranty. Attention: to guarantee correct and optimal combustion it is very important to correctly and hermetically close the top cover after servicing.
AT LEAST TWICE A YEAR: ·Clean the flue outlet. If there are any horizontal sections, inspect them and clean out any ash and soot deposits before they block the passage of the flue gases.
AT THE END OF THE WINTER SEASON (or whenever necessary) ·Perform a thorough overall cleaning of the firebox and pans with brushes and vacuum cleaners.

A vacuum device simplifies the ash cleaning procedure. The front and side casings must be cleaned when the heater is cold using a soft cloth and water. It is also normal to find partially or totally unburned pellets in the ash pan. The door of the combustion chamber must only be opened when the appliance has completely cooled down: when it is opened it is normal for some ash to spill onto the floor.
ATTENTION: after cleaning it is mandatory to carefully check that the combustion chamber door is firmly closed and airtight. ATTENTION: the generator, the smoke channel and flue outlet must be cleaned in accordance with the specifications described above and use of inflammable products is strictly forbidden: using inflammable products can create dangerous situations. Failure to carry out the necessary maintenance or if only partial maintenance is carried out will affect the correct functioning of the appliance. Any problems resulting from total or partial lack of cleaning or maintenance will immediately void the warranty. ATTENTION: if the appliance remains inactive (and/or not used for over a month) the generator, the smoke discharge tube and the flue outlet must be thoroughly cleaned and checked for any possible obstructions (e.g. birds nests in the chimney cap) before restarting.

The smoke outlet must be fitted in compliance with standard UNI 7129/92, UNI 10683 and EN 14785 and it must observe the reference values laid down in the standard, in particular, the outlet must comply with fire prevention regulations.
It is important to carefully follow the instructions set out below: failure to observe these instructions could
cause serious damage to the product, to the system, to objects and to persons using the generator.

9.2 ROOM VENTILATION
ATTENTION: the presence of extraction fans or similar appliances, if operating in the same room or space in which the product is installed, could cause problems for the correct operation of the product. ATTENTION: do not obstruct the vents or the air inlets on the appliance.
The room where the appliance is installed must have a good air flow to guarantee air for the appliance for the combustion process and for ventilation of the room. The natural air flow must take place directly through permanent openings on the outer walls or through single or multiple ventilation ducting (paragraph 9.2.1). The ventilating air must come from outside and if possible, away from sources of pollution. The openings in the walls must comply with the following conditions: · have an unobstructed section of at least 6cm² for each Kw of installed thermal power, with a minimum limit of 100cm²; · be made in such a way that the vent openings, both on the inside and outside of the wall, cannot be obstructed; · be protected with grills or similar systems that do not reduce the opening section indicated above; · be situated at a height near floor level and they must not obstruct the correct operation of the combustion product discharge devices; if this position is not possible the section of the ventilation openings must be enlarged by at least 50%.
9.2.1 VENTILATION FROM ADJOINING ROOMS The air flow can also be obtained from an adjoining room as long as: · the adjoining room is equipped with direct ventilation in compliance with the paragraphs described above; · only appliances connected to the exhaust pipe are installed in the room that is ventilated; · the adjoining room is not used as a bedroom or a common area of the building; · the adjacent room is not a room with a fire hazard, such as storage sheds, garages, combustible material store rooms, etc…; · the adjoining room does not become a vacuum compared to the room to be ventilated due to a reverse draught effect (the reverse draught can be caused by the presence in the room of either another heating appliance running on any type of fuel, a fireplace, or any suction device, which have not been provided with an air intake) · the air flow from the adjoining room to the room to be ventilated is unobstructed through the permanent apertures having an overall net section of no less than that indicated above. These apertures can be obtained by enlarging the space between the door and the floor.
9.2.2 SINGLE OR MULTIPLE VENTILATION DUCTING If the combustion air is supplied through pipes, the available draught, produced by the installed appliance in use and by the corresponding combustion product evacuation system, must be greater than the sum of the resistance offered by the pipes (frictional resistance, resistance due to direction changes, cross-sectional restrictions, etc…). The single ventilation pipes can be vertically and horizontally oriented: the length of the horizontal sections must be reduced to a minimum. The connectors between pipes with different orientations must not have any reduced cross-sections with sharp bends. The angle of connection between the axes of two successive pipes must not be less than 90°. For combustion air supplied through branched pipes, the sum of the resistance offered by the pipes (frictional resistance, resistance due to direction changes, cross- sectional restrictions, etc….) can be a maximum of 10% of the available draught, produced by the various appliances in use installed on the various floors and by the combustion product evacuation system. The branched ventilation pipes must be vertically-oriented with an uphill run. The inlet vent to the room to be ventilated must be located down low and in a position where it does not interfere with the discharge of combustion products and must be protected by a grill or similar device.
9.3 SMOKE OUTLET
The smoke channel, the exhaust pipe, chimney and flue outlet (defined as the system for the evacuation of combustion products), are parts of the heating system and they must comply with the legislative requirements of the Ministerial Decree DM 37/08 (ex Italian Law 46/90) and to the applicable specific installation regulations, according to the type of fuel. Fireplaces, stoves and barbecues must not be installed in locations where gas appliances type A and type B are present and operating (for the classification see UNI 10642 and UNI 719). The connection between the appliance and the flue outlet must only receive exhaust from one heat generator.

ENG

The installer must provide one or more access points on the flue outlet to check the emissions once the appliance has been installed; these access points must be made in such a way as to be air-tight sealable to prevent exhaust gas leaks. The appliance is equipped with a smoke exhaust motor, it works in low pressure and with very low smoke temperatures, consequently it is recommended to insulate it and to ensure that the flue outlet is sized appropriately in order to avoid the possible risk of creating condensation.

9.3.1 CHIMNEY TYPES The following types of chimneys, constructed as described, are possible: · System: Chimney installed using a combination of compatible components (flue liner, insulation, outer casing etc…), constructed or specified by a single manufacturer and CE certified in accordance with the applicable standard;
· Composite chimney: Chimney installed or constructed on site using a combination of compatible components such as flue liner (wall directly in contact with the smoke), and possibly also insulation and outer casing (wall) that may be supplied by different manufacturers or by the same manufacturer. · Relining: operation involving the installation of a specific pipe in an existing shaft (even if newly constructed) made of noncombustible materials, free from obstructions and for single use.

9.3.2 FLUE OUTLET / FLUE SYSTEM COMPONENTS Every chimney must have minimum number of components as laid down by standard UNI EN 1443 which are also indicated in the figure below:

9.3.3 CONTROLS PRIOR TO INSTALLING THE APPLIANCE

The user must possess a certificate of conformance for the flue outlet (Ministerial Decree 22 January 2008, no. 37). The flue outlet must be built in compliance with UNI 10683. The smoke exhaust shown in the following figures is the best solution to ensure the discharge of smoke even when the fan is not operational, such as for example if there is an electrical power failure. A minimum drop of 2/3 metres is required between the T terminal on the outside of the building and the outlet at the back of the generator, to ensure that residual combustion smoke is discharged in the case described above (otherwise the residues would stagnate inside the firebox and exhaust into the environment with added the possibility of explosions). The figures illustrate the best solution for discharging the smoke out through the roof or into the flue outlet. If you prefer to exhaust the smoke from the roof insert a union tee with inspection cap, connecting brackets suitable for the height of the flue outlet, flashing that crosses the roof and chimney cap to protect against bad weather conditions. If you decide to use the classic masonry exhaust provide a union tee with inspection cap and suitable supporting brackets. If the flue outlet is too big it is necessary to insert a stainless steel or porcelain-coated steel tube with a diameter not exceeding 150mm.

Seal area where the inlet and outlet part of the smoke exhaust meets the wall. It is strictly forbidden to apply mesh to the end of the outlet tube , as it could cause the appliance to malfunction. If the smoke tube is installed in a fixed position it is advisable to provide inspection openings for clean-out purposes especially in the horizontal sections. See the diagram. These openings are essential to allow for the removal of ash and unburned products which tend to accumulate along the discharge path. The appliance functions with the combustion chamber in a vacuum, while the discharge of smoke to the flue outlet has a slight pressure, consequently it is imperative to ensure that the discharge system is hermetically sealed. The smoke discharge tube must be made from suitable materials such as for example: porcelain-coated steel tubes, and the various fittings sealed with red silicone (resistant to 350°C). The outer casing of the tube must be made with insulating material (mineral wool, ceramic fiber) or use pre-insulated tubing. THE FLUE OUTLET MUST BE USED ONLY FOR THE APPLIANCE. It must be possible to inspect and remove all the smoke tube sections for clean-out purposes.

ATTENTION: if the flue outlet is not sufficiently insulated and /or if it is too long it could generate condensation. It is advisable to provide a condensation drain near the smoke outlet of the appliance. The appliance must always and only be installed in a single flue outlet system dedicated exclusively to the appliance. If the generator is connected to a non-compliant flue system the appliance could rapidly deteriorate due to an abnormal, continuous overheating: in this case the damaged parts will not be covered by warranty.

IF THE CHIMNEY CATCHES FIRE DO NOT HESITATE TO CALL THE FIRE BRIGADE IMMEDIATELY.

12 ­ INFORMATION FOR THE SKILLED TECHNICIAN

12.1 MAIN COMPONENTS AND THEIR POSITION

SMOKE PRESSURE SWITCH This is a safety switch that stops the screw feeder motor whenever necessary. The main cause for the pressure switch tripping is a blocked flue outlet or smoke exhaust pipe. Note that it is strictly forbidden to apply any kind of mesh screen to the end of the pipe. When the holes of the mesh clog up they create a plug that trips the pressure switch which stops the pellet feeder.
SCREW FEEDER MOTOR This motor is powered at regular on/off intervals controlled by a microprocessor. The operation of this motor is affected when: The motor’s thermal cutout trips; the pressure switch trips due to blocked smoke exhaust; the generator is shut down intentionally or the heater shuts down because it runs out of pellets; the manual reset thermostat trips.
SMOKE SUCTION UNIT This is activated when the start up signal is given. Initially it activates at the maximum capacity, and then self adjusts to the optimal speed. To enable the evacuation of the smoke and for greater safety of the system, the smoke suction unit continues to operate for a preset period of time from when the appliance shuts off.
BRAZIER CLEANING MOTOR This is a patented system that creates a continual movement of the combustion pellets inside the burner which consequently cleans the burner.
SMOKE SENSOR Continually detects the outgoing smoke temperature. It authorises the passage from the Start stage to the Work stage.
EXPANSION TANK This is a safety device for the appliance used to compensate the increased water volume in the appliance due to its increasing temperature (Attention: this tank is intended solely as protection for the appliance).
SAFETY THERMOSTAT WITH MANUAL RESET When the temperature exceeds 98°C the pellet feed screw shuts down. After having verified and solved the causes for the overtemperature, reactivate the appliance by unscrewing the plastic cover of the thermostat and press the button (the temperature of the appliance must have dropped considerably).
SPARK PLUG It is activated in the START phase. It heats the incoming air to the brazier up to 800°C, which promotes the first combustion of the pellets in the brazier.
AUTOMATIC PURGE VALVE The function of this valve is to eliminate air residues inside the appliance body without the need for manual intervention. Consequently problems such as the following are eliminated: · corrosive processes caused by the oxygen · noise generated by the passage of air in the tubes · air pockets in the heating bodies · cavitation in the circulator pumps. SAFETY VALVE CALIBRATED AT 3 BAR When the calibrated pressure is reached, the valve opens and, by discharging to the atmosphere it prevents the pressure in the system from reaching dangerous limits for the generator and for the components of the system. If it trips verify the reasons and solve the causes for the overpressure. It is recommended to connect this valve to an outlet to avoid damaging the material around the appliance and to prevent damage caused by hot water under pressure.
SYSTEM CIRCULATING PUMP This device conveys hot water produced by the appliance to the usage points. The circulating pump signal appears to indicate that it is operating.

12.2 GUIDELINES FOR CORRECT INSTALLATION
· Read this instruction booklet. · The appliance must always be switched off from the control panel. It is forbidden to switch off the appliance by means of the main switch 0/I. · The appliance must never be disconnected from the electrical power supply and the power supply must never be cut off during normal operation. Whenever the appliance is deliberately disconnected from the electric power supply smoke could be emitted into the room. · Do not install the appliance with horizontal wall outlets only: Evacuation of products of combustion by natural draught must always be guaranteed as well. Unsuitable installation of the outlets could cause a forced shut down of the appliance due to overpressure of the exhaust smoke caused by a gust of wind. · At the first startup, run the heater at the maximum power in a well-ventilated room, in order to dispose of the smoke generated by the complete dryness and baking of the silicates contained in the enamel coating of the combustion chamber. · Do not install a grill or outlet terminal that could slow down the flow of the combustion gases: this would obviously cause the appliance to malfunction. · Keep the appliance clean and check the burner as described in these instructions. · Clean the smoke outlet regularly. · Use good quality pellets: use of poor pellets can result in up to 50% less efficiency. · The pellets must be stored in a well-ventilated, dry place. · The generator door must always remain closed during normal operation. · Do not touch hot outer surfaces, unless with special equipment. · Do not pour the pellets directly into the brazier. · Keep fuel and inflammable materials at a suitable distance. · Use only original spare parts supplied by the manufacturer.
