CHANGING THE ROOM AIR POSITION

The appliance has the room air positioned at the “front” by default.
For upper ventilation, request the assistance of a Technical Service Centre:

1. Remove the cast iron top by unscrewing the two fixing screws.
2. Remove the upper closing panel of the room air duct.
3. Remove the front closing panel of the room air duct.
4. Refit the front closing panel of the room air duct in the upper position.

For no reason whatsoever must the appliance be operated with both air passages closed. Doing so may damage the appliance and void the warranty.

HOT AIR DUCTING (DAHIANA plus VFS)
The pipe used for ducting the hot air must have an internal diameter of 80 mm and it must also be insulated or at least be protected against heat dispersion. THE RELEVANT HOT AIR DUCTING PIPE MUST BE INSTALLED BY QUALIFIED PERSONNEL AND/OR BY THE MANU FACTURES’S TECHNICIANS

Additional thermostat to control the duct motor
For models with duct motors, it is also possible to thermostat the motor itself. The connection to an external thermostat will allow for the duct motor to be controlled regardless of stove operation. At this point, simply set the desired temperature on the thermostat; the thermostat will command the operation of the second motor:

• when the temperature has not been reached (contact closed) the second motor will follow the operation of the stove.
• when the temperature has been reached (contact open), the motor will switch off.
• The duct thermostat terminal features a standard bridge. See the drawing to the side.

Operation in air ducting with thermostat or probe (optional)
The stove is fitted with an independent motor for ducting. The connection of an external thermostat or temperature probe (NTC 10K) in the input, located in the rear part of the stove, makes it possible to control the air ducting motor independently of the stove. Suffice it to connect the thermostat/temperature probe and set the desired temperature. For information on air ducting settings see the chapter:” Menu – Ducting” with ambient thermostat (optional) Remove the jumper and connect the ambient thermostat in the room that needs to be temperature-controlled through air ducting. 3 control modes:

Stove positioning
To ensure the stove works correctly, it should always be positioned so that it is perfectly level, using a spirit level

Note for CORRECT operation
The following indications must be respected for the correct pellet stove operation: Both during stove operation and when it is not used, all hatches (pellet hopper, door, ash drawer) must remain closed at all times. They can be opened only for the time required to load the fuel and for maintenance. Failure to comply with the above during operation will cause the display to show the following: “CLOSE HOPPER – STOVE DOOR”
This indication means that you have 60 seconds to close the hatch/door and the pellet lid. After 60 seconds, during ignition, the stove will go into “DEPR ALARM” mode, while during normal operation the stove will go into “COOLING STAND BY” mode before automatically resuming operation once the conditions are satisfied (cold stove, etc.).bulb thermostat reactivation The figure shows the position of the hopper safety thermostat (A). It is recommended to contact the qualified technician if one of the thermostats is triggered, so as to verify the cause.

Fuse
If the stove is not powered, have the condition of the fuse (B) checked by a qualified technician.

Pellets and loading
Pellets are made by subjecting wood shavings i.e. the rejects of pure unpainted wood from sawmills, carpentry products, and products from other activities connected to woodworking and transformation, to very high pressures. This type of fuel is fully ecological as no glues are used for its compaction. In fact, pellet compactness is guaranteed over time by a natural substance found in wood: lignin. In addition to being an ecological fuel, and making the best use of wood residue, pellets also have a series of technical advantages. While wood has a calorific value of 4.4 kWh/kg (with 15% moisture, therefore after approximately 18 months of curing), that of pellets is 5 kWh/kg. Pellet density is about 650 kg/m3 and water content is equal to 8% of its weight. For this reason, pellets do not need to be cured to obtain a sufficient heat yield.

The pellets used must be class A1 certified according to the standard ISO 17225-2 (ENplus-A1, DIN Plus, or NF 444 of the following category: “High- quality NF combustible wood pellets”). UNI EN 303-5 with the following characteristics: water content ≤ 12%, ash content ≤ 0.5%, and lower calorific value >17 MJ/kg (in the case of boilers). The Manufacturer recommends using pellets with a diameter of 6mm with its products.
Pellet storage To guarantee combustion without problems, the pellets must be kept in a dry place. Open the tank lid and load the pellets using a scoop.

THE USE OF POOR-QUALITY PELLETS OR ANY OF HER MATERIALS WILL COMPROMISE STO VE FUNCTIONS, VOIDING THE WARRANTY AND RELEASING THE MANUFACTURER OF LIABILITY. Pellet hopper – pressurized closure. During stove operation, the pellet hopper lid must always be closed. Do not place the bag directly on the stove to load the tank. Always use a scoop to load the tank. Do not rub or place weights on the tank seal. Keep the tank cover seal supporting surface clean at all times. Check the conditions of the seal frequently. If damaged, contact your local authorized technician.

general warnings
Advice to follow for the first start-ups of the product: During the first hours of operation, there may be some smoke or odors, but they are due to the normal “thermal break-in” process. During this process, the duration of which changes depending on the product, it is recommended to:

Ventilate the room well

• If present, remove any majolica or natural stone parts from the top of the product
• Activate the product at the maximum power and temperature
• Avoid remaining in the room for a long time
• Do not touch the surfaces of the product

Notes
The process is completed after a few heating/cooling cycles. Do not use for the combustion of elements or substances other than those indicated in the manual. Before turning on the product, it is necessary to perform the following checks:

• If it is intended to be connected to a hydraulic system, it must be complete and fully functional and in compliance with the instructions given in the product manual and with the relevant regulations in force.
• The pellet hopper must be completely loaded
• The combustion chamber and the burn pot must be clean
• Make sure that the fire holder, the ash pan, and the pellet hopper close hermetically (if present in the hermetic version); they must be closed and there must be no foreign bodies in the sealing elements and gaskets.
• Check that the power cord is properly connected
• The switch (if present) must be set to position “1”.

Make sure that the bottom of the burn pot is free from residue and deposits. The holes at the bottom must be completely free to guarantee proper combustion. The “EASY SETUP” function can be used to adapt combustion based on the described needs.

IT IS PROHIBITED to use the appliance without the partition AND/OR FLAME GUARD (see figure on side). REMOVAL will compromise the safety of the product and result in the immediate nullification of the warranty period. In the case of wear or deterioration, request after-sales assistance to replace the part (Replacement is not covered by the warranty as the component is subject to wear).

No ignition
The appliance may fail to light because the auger is empty and not always able to load the burn pot fast enough with the pellets needed for normal ignition. If the problem occurs after only a few months of operation, check that the routine cleaning described in the stove handbook has been carried out correctly

Operation and logic
DO NOT USE ANY FLAMMABLE LIQUIDS FOR IGNITION! DO NOT ALLOW THE BAG OF PELLETS TO COME INTO CONTACT WITH THE BOILING HOT STOVE DURING THE FILLING PHASE! In the event of continued failure to light, contact an authorized technician.

Ignition
Once the previously listed points have been checked, press key 1 for three seconds to ignite the stove. During ignition, the stove will check for a flame for a period of 15 minutes. When the right temperature is reached, the stove will switch from ignition to PREPARATION.

PREPARATION
During the preparation phase, the stove stabilizes combustion, increasing it progressively, to then start ventilation and switch to WORK

Work
In the work phase, the stove switches to the Set Power defined by the user, heating the room until the Set Thermostat is achieved. See the next heading.

SET thermostat
The ambient Set thermostat can be set using keys 4 and 5, from LOW-TA – 7°C – 37°C – HOT. If the value is between 7°C – 37°C, the stove checks the room temperature using a probe on the machine. Once the set temperature has been reached, the stove automatically reduces the power, guaranteeing the best comfort and reducing pellet consumption: this process is called “modulation”.

LOW-TA / hot
If the Set Thermostat is “LOW-TA” (set under the 7° threshold), temperature checking is entrusted to the additional thermostat contact, thus bypassing the onboard temperature probe. If the contact is closed (request), the stove works at the set power. If the contact is open (fulfilled), the stove works at minimum power. If the setting is on “HOT” (set above 37°C), the stove only works at the set power, thus bypassing the external contact and the temperature probe.

SET POWER
Set Power has 5 operating levels. The power can be changed with keys 2 or 3. Power 1 = minimum level – Power 5 = maximum level. Press key 1 to exit and save the change.

Auto blow
During the work phase, the stove cleans the burn pot at regular intervals with an “auto blow”. When this procedure starts, a message is displayed. During the “auto blow” procedure, the pellet feed slow down and the fumes motor increases. After cleaning, the stove resumes operation in normal conditions.

Switch-off
Press key 1 for three seconds. Once this operation has been performed, the appliance automatically enters the switch-off phase, blocking the supply of pellets. The flue gas exhaust motor and the hot air flow motor will remain on until the stove temperature has dropped below the safety settings.

Reignition
The stove can only be re-ignited if the temperature of the exhaust fumes is lower than the preset threshold and the minimum safety time has passed.

Front air
This menu allows you to set the front air motor speed. Range: (COMFORT, AUTO). When COMFORT mode is selected, the front airspeed is reduced with respect to AUTO mode.

WARNINGS : If the appliance is installed with air ducting active, but an ambient probe or thermostat for air ducting (i.e. the jumper is kept on the ducting terminal), and the AIR ZONE CONTROL function is activated, it sends heat into the ducting regardless of the temperature of the room receiving the ducting.

EASY SETUP
The volumetric weight of the pellet is the ratio between the weight and the volume of the pellet. This ratio may change without altering pellet quality. By using the EASY SETUP function, it is possible to dose the pellets by increasing or decreasing the preset values. In the stove program, the available values range from “– 3” to “+ 3”; all stoves are calibrated during production with the optimal value, which is 0. If you notice an excessive deposit in the burn pot, access the EASY SETUP program and lower the value by one unit to “- 1”; then wait until the next day and if there is no improvement, decrease again, to a maximum of “- 3”. If, on the other hand, it is necessary to increase the pellet dosage, switch the factory value from “0” to “+ 1, + 2, + 3” as required.

Cleaning and maintenance
Always follow the instructions in complete safety!

•  Make sure that the power cord is unplugged because the generator may have been programmed to switch on.
•  That the generator is cold all over.
•  That the ashes are completely cold.
•  Ensure efficient air exchange in the room during the product cleaning operations.
•  Poor cleaning will compromise correct operation and safety!

Maintenance

For correct operation, the generator must undergo routine maintenance by a qualified technician, at least once a year. The periodic inspection and maintenance operations must always be performed by specialized, qualified technicians, who operate in accordance with the laws in force and the instructions given in this use and maintenance manual. Every year, have the fume extraction system, flue pipes and “T” fittings, including the inspection caps cleaned. If present, also clean the elbows and horizontal sections! The generator cleaning FREQUENCY is INDICATIVE! Depends on the quality of the pellet used and on how often it is used. These operations may sometimes need to be performed more often

Periodic cleaning under user’s responsibility
The periodic cleaning operations, as indicated in this use and maintenance manual, must be performed with the utmost care after reading the instructions, procedures, and frequency described in this use and maintenance manual.

Cleaning the surfaces and covering
Never use abrasive or chemically aggressive detergents for cleaning! The surfaces must be cleaned when the generator and coating are completely cold. For the maintenance of the surfaces and metal parts, simply use a cloth dampened with water or water-neutral soap. Failure to follow the instructions may lead to damage to the generator surfaces and invalidate the warranty.

Cleaning the ceramic glass
Never use abrasive or chemically aggressive detergents for cleaning! The ceramic glass must be cleaned when the glass is completely cold. To clean the ceramic glass, simply use a dry brush and some damp newspaper dipped in ash. If the glass is very dirty, use a specific cleaning agent for ceramic glass. Spray a small amount on a cloth and use it on the ceramic glass. Do not spray the cleaning agent or any other liquid directly on the glass or seals! Failure to comply with these instructions may damage the surfaces of the ceramic glass and cause the invalidation of the warranty.

Cleaning the pellet hopper
When the hopper is completely empty, disconnect the power cord of the generator, remove the residues (dust, chippings, etc.) from the empty hopper, and then fill it up. The pellet hopper gaskets, burn pot, and fire door guarantee correct stove operation. These need to be periodically checked by the user. If they are worn or damaged, replace them immediately. These operations must be performed by a qualified technician. If the power cord is damaged, it must be replaced by the service center or by a similarly qualified person, so as to avoid all risks.

BURN POT and COMBUSTION
**Chamber

**

• Vacuum the residue in the burn pot
• Remove the burn pot completely from the relevant compartment;
• Vacuum the ash from the burn pot slot, ignition plug pipe holder, and combustion chamber.
• Clear/clean all the holes in the burn pot.
• Re-position the burn pot in its slot and push it towards the firewall.
  NOTE: Use a suitable ash vacuum cleaner with a special separate container for the collected ashes.

Routine maintenance performed by qualified technicians Routine maintenance must be performed at least once a year. Since the generator uses pellets as solid fuel, it requires annual routine maintenance, which must be performed by a Qualified technician, using only original spare parts. Failure to comply may jeopardize the safety of the appliance and invalidate the warranty conditions. By observing the cleaning schedule reserved to the user described in the use and maintenance manual, the generator will be guaranteed correct combustion over time, thus preventing any faults and/or malfunctions that may require subsequent technical assistance. Requests for routine maintenance are not covered by the warranty.

GASKETS, pellet hopper lid, DOOR, ASH DRAWER AND BURN POT, INSPECTION OF SMOKE DUCTS The gaskets ensure the proper sealing of the stove and therefore its proper operation. They must be periodically checked and immediately replaced if worn or damaged. These operations must be carried out by a qualified technician.

Connection to the flue
Annually, or in any case, each time the flue pipe needs to be vacuumed and cleaned. If there are horizontal sections, the residue must be removed to prevent it from obstructing the flow of fumes. Shut-down (end of season) At the end of each season, before turning the stove off, it is advisable to completely empty the pellet hopper, removing any pellet residue and dust with a vacuum cleaner. Furthermore, please disconnect the generator from the mains electricity and, for greater safety especially in the presence of children, remove the power cord.
