You are advised to contact authorised staff to replace spare parts, worn parts and for extraordinary maintenance of the the product.

1.9 IDENTIFICATION PLATE
The plate placed on the back of the product outlines all the characteristic data of the appliance, including the manufacturer’s data, the serial number and the CE marking.
1.10 PRODUCT DISPOSAL
Demolition and disposal of the product is the exclusive responsibility of the owner, who should do so in compliance with legislation in force in his country on safety matters, with respect of and safeguarding the environment. At the end of its useful life, the product must not be disposed of as urban waste. It can be delivered to specific differentiated waste collection centres made available by municipal administrations, or dealers who provide this service. Disposal of the product as differentiated waste means possible negative consequences for the environment and health are avoided, deriving from inadequate disposal. Furthermore, it allows recovery of materials composing the product to obtain important savings in energy and resources.

CHARACTERISTICS OF THE PELLETS
Wood pellets are fuel made of pressed sawdust, often recovered from carpentry processing waste. The material used cannot contain any foreign substance such as glue, varnish or synthetic substances. Sawdust, after drying and cleaning of impurities, it is pressed using a matrix: due to the high pressure, the sawdust heats activating the natural binders in the wood; by doing so, the pellet maintains its shape even without adding artificial substances. The density of wood pellets varies based on the type of wood and can exceed 1.5 – 2 times that of natural wood. The cylinders have a diameter of 6mm and a variable length of 10 to 40mm. Their density is equal to approx. 650 kg/m3. Due to the low water content (< 10%), they have a high energy content. The main quality certifications for pellets on the European market today guarantee the fuel is within class A1 in according to ISO 17225-2:2014 (formerly EN 14961). Examples of these certifications are for example ENPlus, DINplus, Ö-Norm M7135, and guarantee they comply in particular with the following characteristics: · heating power: 4.6 ÷ 5.3 kWh/kg; · water content: 10% of weight; · percentage of ash: max 1.2% of weight
(A1 under 0.7%); · diameter: 6±1/8±1 mm; · length: 3÷40 mm; · content: 100% untreated wood without
any additional binder substances (percentage of bark max 5%); · packaging: in sacks made from eco-compatible or bio-degradable.

1.11 HERMETIC PRODUCT
The products manufactured with a perfectly hermetic structure do not consume oxygen in the environment, since they take all the air from outside the home (if correctly installed) and can therefore be positioned inside all homes with a high level of insulation, such as “passive houses” or “with high energy efficiency”. Thanks to this technology, there is no risk of smoke emissions in the environment and no ventilation grates are necessary. As a result, no cold air flows are created in the environment making it less comfortable and reducing the overall efficiency of the system. Hermetic products can also be installed in the presence of forced ventilation or in premises which can go into negative pressure compared to outside.

The manufacturer recommends, for its products, use of class A1 certified fuel according to the standard En ISO 17225-2:2014, or certified DIN PLUS (more restrictive than class A1) or O-NORM M7135.
Pellets must be kept in a dry environment which is not excessively cold. You are also advised to keep some bags of pellets where the product is installed and operating, to dry them of any humidity present. Non-compliance with this aspect reduces the thermal power of the fuel and means greater maintenance must be done on the product.

3.2 SMOKE CHANNEL AND FITTINGS

The manufacturer cannot be held in any way liable in the event of installation non-compliant with legislation in force, of incorrect premises air exchange or electrical connection non-conforming with standards and/or inappropriate use of the appliance. Installation must be carried out by a qualified technician, who will issue the purchaser with a Declaration of Conformity for the system and will assume complete responsibility for final installation and resulting good operation of the product. In particular, he should ascertain: · there is an adequate oxidising air intake and good
smoke discharge compliant with the type of product installed; · other stoves or devices installed do not cause
negative pressure in the room where the product is installed (only for hermetic appliances, a maximum of 15 Pa depression in the surroundings is permitted); · when the product is on, there is no smoke back draught in the surroundings; · smoke evacuation is implement in total
safety (dimensioning, smoke seal, distances from flammable materials..). Once the position is decided where to install the product, you need to pay attention: · if the floor is made of combustible material, you should use protection in suitable material (steel, glass…) which also protects the front part from any falling burning fuel during cleaning operations: · that the floor guarantees adequate load capacity. if the existing building does not meet this requirement, you should take appropriate measures (for example a load distribution plate).

The term smoke channel indicates the piping connecting the appliance to combustion with the chimney flue. For heat generating appliances with an electric fan to expel the smoke, the following installation instructions must be followed, provided by the manufacturer concerning the maximum length and number of curves the smoke channels can have. If no indications are given for maximum values or deriving from preliminary calculations according to UNI EN 13384-1, the following provisions must be applied: · comply with the product standard EN1856-2; · the horizontal sections must have a minimum slope
of 3% upwards; · the length of the horizontal section must be
minimal and its projection on plan must not exceed 4 metres; · the number of changes of direction including
introduction in the chimney flue and excluding that by effect of using a “T” element in the appliances with rear smoke output, must not exceed 3; · the changes of direction must not have an angle over 90°(45° curve recommended); · the section must have a constant diameter equal to the output of the fireplace up to the fitting in the chimney flue; · it is forbidden to use flexible metal and fibre cement piping, furthermore the piping must guarantee pressurised sealing; · the smoke channels must not cross premises in which installation is forbidden of combustion appliances; · Use watertight piping with silicone gaskets. In any case, the smoke channels must be

sealed by combustion and condensate

3.3 CHIMNEY FLUE

3.5 HERMETIC PRODUCT INSTALLATION

When installing the chimney flue, the following provisions must be applied. · comply with the product standard EN 1856-1; · it must be installed using materials suitable to
guarantee resistance to normal mechanical and chemical stress, and have a correct insulation, to avoid the formation of condensate, therefore it must be hermetically insulated; · have a mainly vertical state and not be choked along its length; · be correctly spaced using air cavities and insulated from flammable materials, · the changes in direction must be at most 2 and with an angle not exceeding 45°; · the chimney flue inside the home must however be insulated and can be inserted in a cavity provided it complies with the relevant piping standards; · the smoke channel should be connected to the chimney flue using a “T” joint with an inspectionable collection chamber for collection of fuel residue and, in particular, for condensate collection.
It is not possible to connect the appliance to a chimney flue shared with other combustion appliances or in the presence of hood exhausts.
It is forbidden to use direct wall discharge or towards closed spaces or any other form of discharge not planned by legislation in force in the country of installation (In Italy, only roof discharge is permitted)

In the event of installation of a hermetic product, you can execute one of the following types of connection with the piping:
· smoke discharge (1) and recovery of oxidising air directly from outside (2)

· smoke discharge (1) and oxidising air channelling (2) taking advantage of its coaxial discharge

to expel the smoke and pick

You are advised to check the safe distances which must be complied with in the presence of combustible materials and the type of insulating material to use (data available directly on the chimney flue plate)

3.4 CHIMNEY STACK

The standard UNI 10683 states the stack must meet

the following characteristics:

· the smoke outlet section must be at least

double the inner section of the chimney;

· shaped to prevent

water or snow penetration;

· be built in such a way that wind

cannot affect the smoke outlet

(wind-proof cap);

· the opening measurement, which is measured

between the lower coverage protective layer

and the lower point of the

smoke outlet section into the atmosphere, must be

outside the back draught area;

· Be built far from antennas or

satellite dishes and must never be used as a

support.

3.6 EXAMPLES OF CORRECT INSTALLATION

installation of the product (A) necessary for the hori-
zontal section for connection to an existing chimney flue. Based on a slope of 3-5%, to reduce ash deposit in the horizontal pipe section which must not be over 3m (1). The existing chimney flue must be inspectionable (2).

Installation of the product (B) requires an insulated

chimney flue (3) with an internal diameter of no less than 100mm, since all the smoke piping was assem-
bled outside the home.

Installation of the product (C) requires a single wall

chimney flue (4) for the section inside the home. Relating to the part placed in the attic, you are ad-
vised to install a chimney flue Ø120mm, with perforation for passage of the piping, extended to:
· minimum 100mm around the pipe if in contact with inflammable parts such as cement, bricks, etc.;
· minimum 300mm around the pipe (or as described in the plate data) if in contact with
flammable parts such as wood etc. In both cases, insert adequate insulation (5) be-
tween the chimney flue and the attic. You are advised to check and comply with the
plate data of the chimney flue, in particular the safe distances from combustible materials.
The previous rules also apply for holes made on
walls.

On the lower part of the chimney flue, for all 3 installations, a “T” fitting (6) was assembled with an inspection plug (7), as well as on the inlet of the
chimney flue.

The upper part of the chimney flue, for all 3 installations, has a wind-proof chimney pot (8) assembled.

In the home, for all 3 installations, a grate is planned

to guarantee correct oxygenation of the premises

where the product is positioned.

Grate not necessary if appliance is hermetically

sealed.

It is not recommended to install a 90° curve as an in-

itial section which would quickly cause ash to block

smoke passage, causing draught problems

in the appliance.

Reduced Nominal Reduced Nominal

The chimney flue must always be cleaned, since deposits of soot or fuel residue reduce the section blocking its draught, compromising good operation of the product and, if in large quantities, can catch fire. It is compulsory to have a qualified chimney sweep clean and check the chimney flue and the stack at least once a year or after prolonged stoppage due to non-use of the appliance. At the end of the control/maintenance, ask for a report to be issued stating the system is safe. Lack of cleaning prejudices safety of the system.

want to use as the display standard. Press the key OK

to confirm and go to the next screen.

To work correctly, the handheld device requires interfacing with the electronic board inside the product. For this reason, the display shows a first installation message.

CONFIGURATION OF T.EXT THERMOSTAT
If you want to manage the appliance from a different room (in that specific room, the remote handheld device cannot communicate), you can connect an external thermostat to the product, to allow modulation of combustion or, by activating a particular function, allow switch on or off of the product. As in the figure below, connect the terminals of the thermostat to the terminal board on the back of the product (near the emergency panel).

TERMINAL

EXTERNAL THERMOSTAT

If first use of the handheld device, choose YES with

the selection keys

.Press the key OK to confirm

and go to the next screen.

Follow the guide instructions to link via remote the
appliance to the display, as outlined in the figure below.

Following electrical connection, to allow the control unit to recognise the presence of the t.ext, the recognition function must be enabled from the SETTINGS menu (see the “ENABLE EXTERNAL THERMOSTAT” paragraph)

Keep the remote communication key of the electronic board pressed for a few seconds, placed on the rear of the product, to start the unit search procedure.
6.3

By enabling the function that allows external thermostat enabling, on the handheld device reading and management of the ambient temperature are inhibited. The handheld device displays TON if required, TOFF if the temperature set on T.ext is reached.
PELLET LOADING

The yellow, flashing led, under the icon the electronic board is waiting to
receive the handheld device signal.

indicates

Fuel is loaded by inserting pellets from the upper part of the product, opening the door. Ensure the content of the bag of pellets does not fall around the edges of the tank, paying particular attention to centring, during the loading phase. Also avoid the pellet packaging coming in contact with hot surfaces.

Pressing the confirm key OK on the handheld device, the components can communicate with one another. A tick sign on the display, accompanied by an acoustic signal, indicates the remote connection operation has successfully concluded.

Ensure you correctly close the cover of the tank again after loading the pellets. Closure is controlled by an electronic contact (for the models where planned). In the event of non-closure, a sign warns the user to pay attention to tightening, before passing to alarm mode, in the event the warning is ignored.

If the batteries are replaced, you don’t necessarily

have to follow the initialisation procedure of the

handheld device. In this case, when the display

shows the message “FIRST INSTALLATION?”,

select NO and press the confirm OK

key.

STATUS SCREEN. To recognise switch off of the appliance in AIR CON. COMFORT condition, the screen 1 must be displayed.

To recognise the appliance is about to switch on in the AIR CON. COMFORT condition, the screen 2 must be displayed.

The function described in the paragraph, once activated, allows heating of the ambient, taking advantage of the maximum speed of the fan. The scope is to supply the maximum heat to the detriment of a minor acoustic comfort. In this respect, the possibility exists of adjusting the time slot for operation of the POWERFUL function.
With the POWERFUL function enabled and ventilation disabled (for models that include the optional ventilation), the fan activates autonomously at maximum speed for the activity time of the function.
The logic, relating to this type of management, is as follows:

USER:

the user reserves the right to set the ambient temperature he or she
wants and the power to the fireplace useful to reach this temperature.

POWERFUL: the end user manually activates the function or using the settable
time slot. The appliance is released from the power set, also forcing ventilation at the maximum speed, for 5 minutes or up to when the setting is reached, or if the time slot or the user disables the function.

PRACTICAL EXAMPLE: Ambient setting at 21°C; Saving mode setting at 3 minutes; Restart °C setting at -2°C compared to setting. The appliance switches off as soon as the temperature in the home reaches the value set + 3 minutes in saving mode. The product switches on when a temperature is detected of 18°C (21°C – 2°C – 0.5°C tolerance). You can also activate the function using an external thermostat, taking into consideration that this does not include the hysteresis values.
You are advised to use an external thermostat with its hysteresis value settable up to a maximum of 3°C. Operation of the appliance could start the switch on and off phase many times during the day; this could compromise the duration of switch on resistance.

18 CLEANING THE APPLIANCE
Product installation must take place in in such a way as to ensure easy access to the appliance itself and to the flue for cleaning and maintenance operations.
Please carefully adhere to the following instructions for correct cleaning of the appliance. Non-compliance could cause its malfunctioning.
Before carrying out any cleaning operation on the appliance, take the following precautions:
· switch off the product and in “OFF” status disconnect the power supply cable;

18.2 CLEANING THE GLASS DOOR
To clean the glass, use a cotton cloth or kitchen paper. You are advised to clean the glass using a damp cloth with water and combustion ash (with an abrasive function), avoiding use of products with additives that could, over time, wear the seals, glass and paint.

With a soft bristle brush, eliminate the combustion particulate, allowing it to fall in the slide beneath.

Do not switch on the appliance if the glass is damaged. Contact the support service to replace it.
OPERATING PROCEDURE: Clean with a cotton cloth as in the figure below:

Vacuum the slide, the hatch and the surface hidden
by the flame trap, paying attention not to knock the vacuum cleaner nozzle off the vermiculite.

18.3 CLEANING THE ASH PAN
Remove the pan from the appliance and remove the ash deposited, using an ash vacuum cleaner; pay utmost attention to the presence of embers that could still be hot and which could damage the appliance used for cleaning.

The cleaning operations depend on the quality of the pellets used and the frequency of use of the product. It can happen that such operations must be carried out more frequently than stated in the manual.
