2.8 Wiring diagram for zone system

Before installing the heating stove in the house, check the type of heating system;

in case of several zones, a special electronic controller for multi-zone circuits, available as an optional, must be installed. This is to prevent overheating of the heating chamber due to possible simultaneous closing of the zone valves and consequent stopping of hot water flow.

2.9 Plumbing connections

The heating capacity of the unit must be previously established by calculating the building's heat requirement according to current regulations. The system must be provided with all the components for correct and regular operation; in fact according to the rules of proper workmanship in installation, shutoff valves and non-return valves allowing the stove to be isolated in case of maintenance and/or checks, must be interposed between the stove and the heating system.

Proceed slowly during heating chamber water filling, to allow correct and complete evacuation of the air from the vent (for a closed vessel system from 1.1 to 1.5 bar).

The pellet stove has an internal heating circuit complete with circulating pump, safety valves, air vent, temperature probes and pressure transducer.

If the heating system is managed in zones a multi-zone controller, available on request, must be installed.

To display the boiler's water circuit pressure, just press the control panel button P5 for 3 seconds.

During stove transport the gaskets in the plumbing system may come loose and/or break, causing water leaks during normal operation; therefore make sure to check the tightness of the circulating pump and heating chamber connection rings and vent the residual air during water filling and after the first hours of operation.

To connect the stove to a heating system it is advisable to contact a competent technician in order to best optimise the plumbing connections and the performance of the entire system without compromising stove operation.

One of the following optionals must be requested for the connection to the DHW circuit:

- a monostable 3-way valve for installing outside the stove.

After completing the DHW connection it is necessary to access the technical menu of the control and select the type of circuit; every specific DHW function set: DHW EXCHANGER, BOILER or DHW BOILER appears on the display at the moment of heating-DHW switchover with one of the messages given below and remains until the end of the DHW request by the thermostat or flow switch :

Arrangement

PLUMBING CONNECTIONS on back of stove

2.10 Emergency

Suitable fire-prevention devices should be arranged for any eventuality. In case of a fire, proceed as follows:

• Immediately disconnect the plug.
• Extinguish the fire using fire-extinguishers (powder).
• Call the fire department immediately.
• Do not use jets of waters to extinguish the fire.

3 STOVE SAFETY

3.1 Safety distance from flammable materials

To prevent the risk of fire, stove positioning must respect a minimum distance from flammable materials, according to that given in the technical table of the manual and on the dataplate.

Pay attention to the type of floor: for delicate and flammable materials it is advisable to use plates in steel or toughened glass as a support base (see section 2 - Transport and Installation). In case of particularly fragile objects such as furniture, curtains or sofas, increase the stove distance considerably.

3.2 Fume exhaust safety

In normal operation the combustion chamber is in a negative pressure, guaranteeing seal against possible smoke leaks in the room. If a certain vacuum level is not reached or the fume exhaust outlet is blocked, the vacuum switch detects the lack of a negative pressure inside the combustion chamber or the air flow meter detects a lack of air flow and, through the electronic controller, switches off the auger rotation motor, signalling the anomaly with a message on the control panel 'AL8 NO NEG PRESS' or 'AL9 INSUF DRAUGHT'.

3.3 Combustion chamber overpressure safety

Any and/or sudden overpressures in the combustion fumes inside the chamber and fume exhaust ducts are discharged by opening of the safety valves located on the heat exchanger. During normal operation these valves are kept closed by their weight and the negative pressure in the combustion chamber, guaranteeing a seal against any smoke escaping.

Periodically check closing, the integrity of the device and its operation.

3.4 Overheating - safety thermostats

Close-up of a door panel with a black arrow pointing to the left side (no visible text or symbols)

On the front and bottom of the hopper, and precisely on the pellet chute and on the top part of the heating chamber, there are two temperature probes connected to the respective safety thermostats that automatically shut off the pellet supply in case of excessive heating. In this case the extractor and/or fans continue working, allowing the stove to cool down rapidly. The fault is displayed on the control panel with a message 'AL 7 THERMAL SAF'. In case of activation, proceed as follows:

▶ Allow the stove to cool down for at least 45 minutes.
▶ Reset the thermostat by pressing the button near the switch on the back of the stove (figure opposite).
▶ Restart the stove normally.
Pellet hopper thermostat activation temperature : > 85°C
Heating chamber thermostat activation temperature : > 95°C

3.5 Safety against flare-back in the pellet chute

The solutions preventing flare-back are:

▶ negative pressure in the combustion chamber see par. 3.2.
▶ the siphon shape of the pellet chute.
▶ the hopper temperature safety see par. 3.4.

3.6 Overcurrent protection device

The unit is protected against overcurrent by 2A fuses on the power supply of the main stove switch located at the back.

3.7 Power failure safety

A temporary power failure does not limit stove safety and the hopper temperature does not reach high values (< 85°C), given the small quantity of pellets burning in the brazier.

This anomaly can result in some smoke briefly escaping into the room, which does not involve any risk.

Do not tamper with the safety devices.

3.8 Plumbing circuit overpressure safety

A possible overpressure of the water inside the chamber, by P>3 bar, is discharged through activation of the safety valve installed in the plumbing system inside the stove.

Do not tamper with the safety devices.

3.9 Fume extractor fan failure

If the fume extractor fan stops for any reason, the electronic controller instantly stops the pellet feed, displaying the message 'AL4 FAN FAIL'.

4 STOVE USE

4.1 Introduction

The pellet stove has the advantage of combining the heat generated by the combustion of wood with the convenience of automatic water temperature management and the possibility of weekly programming of switching on/off, as well as the connection of a thermostat and/or chronothermostat and start-stop remote control.

For safe and reliable use:

• when lighting and using the unit the first time, unpleasant odours may be created, therefore air the room thoroughly;
• the hopper must only be filled with good quality pellets; make sure the bag does not come into contact with the hot surfaces of the stove ;
• do not put any fuel other than the prescribed pellets in the hopper;
• the unit must not be used as a waste incinerator;
• the boiler must only operate with the fire door always closed.
• the fire and ash door seals must be checked periodically to prevent air from entering;
• to ensure thermal efficiency and correct operation it is necessary to clean the brazier every time pellets are loaded;
• when lighting the stove for the first time, allow it to heat up gradually by setting low operating temperatures (see the section on temperature setting);
• during lighting, operation and shutdown, the stove may creak a little due to the heat expansion.

4.2 Description of control panel

The control panel comprises a backlit LCD, on/off button 'P4', SET/MENU button 'P3', four menu buttons 'P1', 'P2', 'P5', 'P6', and seven stove operation status LEDs.

4.3 Lighting

4.3.1 Check before lighting

Before lighting the stove:

• make sure to have read and understood the information given in the manual;
• follow the oral instructions on operation of the unit provided by the installer prior to use.
• the hopper must be filled with pellets;
• the combustion chamber must be clean;
• the brazier must be completely free, cleaned of any combustion residuals and correctly fitted in the brazier holder;
• check hermetic closing of the ash box and fire door;
• check the connection of the power cable and switching to ON/1 of the switch located on the back of the stove.
• check opening of the delivery and return shutoff valves as well as the water circuit pressure.

• At first startup, remove all the components that could burn (instructions/label) from the stove firebox.
• Any lighting done after long idle periods requires the removal of any residual pellets that have remained inside the hopper, in being damp fuel no longer suitable for combustion, and complete cleaning of the combustion chamber.

4.3.2 Startup stage

To light the stove, press the button 'P4' for 3 seconds: the message 'START' will appear on the display.

This stage is automatic and managed entirely by the electronic controller without the possibility of changing the parameters.

Alternatively the stove can be lit by pressing the buttons P4 and P5 together for 3 seconds. The message AWAITING REQUEST appears on the display. With this mode the stove switches to standby status and carries out the lighting-start stage only if a request for heat is recognised, e.g. to heat the water or for DHW (if available).

• Make sure to check the pellet level in the hopper so that the flame does not go out due to lack of pellets.
• Make sure the unit is off when loading pellets.
• The pellet hopper lid must always remain closed; it must only be opened when loading fuel.
• The bags of pellets must be kept at least 1.5 m from the stove.

4.4.1 Modifying the water temperature setting

To modify the water temperature, press button P1 and then increase or decrease the temperature parameter with buttons P1 and P2. When the water temperature has reached the set value, the power is automatically brought to the min. value, MODULATION status. Want to change the room temperature is necessary to continue with the SET button and then increase or decrease the temperature parameter with buttons P1 and P2

When the fume temperature reaches a set max. value the message 'MODULATE F' appears on the control panel and the stove activates the flame modulation procedure without any user intervention, whereas if the temperature exceeds 285°C the alarm 'AL3 HOT FUMES' appears and the stove activates the shutdown procedure.

4.4.2 Cleaning the brazier

4.4.3 Water heater with heat exchanger quickly

When hot water is required, the display shows the message DHW EXCH and the LED indicated by the tap lights up. The function is carried out only if the stove is on, and the water inside the heating chamber has reached a sufficient temperature. In the remaining cases the service is not provided.

4.4.4 Water heater with storage tank

This type of installation requires the use of an external thermostat or a water probe, which measures the DHW storage tank (puffer) temperature.

In the former case, temperature SETTING is obtained by adjusting the puffer thermostat controller.

In the latter case, to modify the temperature it is necessary to press button P2 on the control panel and then increase or decrease the temperature value with buttons P1 and P2.

The DHW function is activated when the temperature falls below the SET temperature. During the STANDBY phase, the stove automatically lights and goes to WORK mode. Once the work temperature of the heating chamber water is reached, the supply of water to the storage tank (puffer) is activated. The stove display shows the message DHW and the respective LED lights up.

When the SET temperature of the storage tank is satisfied, the STOVE activates the heating system. If there is no further demand, the stove goes on STANDBY or to MODULATION, depending on the settings (see par. 4.6.2). If the stove is in OFF status, it does not light and does not provide the service.

4.4.5 System with puffer / heat storage

This type of installation requires the use of an external thermostat or a water probe, which measures the puffer water temperature.

In the former case, temperature SETTING is obtained by adjusting the puffer thermostat controller.

In the latter case, to modify the temperature it is necessary to press button P2 on the control panel and then increase or decrease the temperature value with buttons P1 and P2.

When the temperature drops below the SET external thermostat temperature:

If the stove is in the AWAITING REQUEST stage, it automatically turns on and goes to WORK status and the supply of water to the puffer is activated when the work temperature of the heating chamber water is reached. When the puffer SET temperature is met, the stove goes to AWAITING REQUEST (make sure to set the STANDBY function to ON, see par. 4.6.2).

If the stove is in OFF status, it does not turn on and does not provide the service.

It is possible to choose the temperature SETTING of the DHW storage tank and of heating from a min. of 54^ C (STD pump start value) to a max. of 80^ C with minimum return temperature not lower than (50-55)^ C in order to prevent condensation inside the chamber.

4.5 Shutting down

To shut down the stove, just press the button 'P4' for about 2 seconds.

The auger is immediately stopped and the fume extractor is brought to high speed, making the message 'FINAL CLEANING' appear on the display.

4.9 Idle period (end of season)

If the stove is not used for long periods, or at the end of each season, it is advisable to proceed as follows:

• remove all the pellets from the hopper;
• disconnect the power supply;
• clean thoroughly and, if necessary, have any damaged parts replaced by qualified personnel;
• protect the stove from dust with suitable covering;
• store in a dry and safe place protected from atmospheric agents.

5 STOVE CLEANING

Stove cleaning is very important to prevent: blackening of the glass, poor combustion, deposits of ash and unburnt products in the brazier, reduced thermal efficiency.

The stove must only operate with the fire door closed.

The fire door seals must be checked periodically to prevent any air from entering; the combustion chamber and pellet duct work in a negative pressure and the fume exhaust in a positive pressure.

Routine cleaning is normally carried out by the customer following the instructions in the manual, whereas extraordinary maintenance, at least once a year, must be performed by the authorised Service Centre.

• Cleaning operations for all parts must be carried out with the stove unplugged and cold;
• Dispose of cleaning waste in accordance with the current local regulations;
• The stove must not be operated without its cladding;
• Avoid the creation of smoke and unburnt products during lighting and/or normal operation.

Given below are the control and/or maintenance operations for correct stove use and operation.

5.1 Cleaning the brazier

Remove the brazier and the ash deposited in the combustion chamber and brazier holder. A suitable vacuum cleaner may be used for this purpose. This operation must be carried out daily, especially in case of accumulated unburnt matter, to ensure perfect combustion conditions, since the brazier holes allow the flow of combustion air.

Brazier Holder clean

The brazier must rest on the brazier holder and precisely on the entire ring band without air gaps.

5.2 Cleaning the ash pan

The ash container is located directly under the brazier - brazier holder. To clean it, open the fire door and remove the ash and any combustion residuals using a suitable vacuum cleaner.

Close the door after cleaning. The ash container can be cleaned every 2-3 days depending on stove use.

5.3 Cleaning the glass

The glass can be cleaned using a damp cloth and specific non-abrasive detergents.

Special slots between the glass, glass stops and fire door at the top and bottom allow air to circulate on the inside surface of the glass. These slots must be kept clean of any deposits of ash and dust. Therefore periodically clean all around the glass, on the inside and outside of the door.

5.4 Cleaning the fume extractor and combustion chamber

The combustion chamber must be cleaned at least once a year, removing all combustion residuals from the internal fume pipes and flueways. To carry out this operation, it is necessary to remove the stove top cover, and the heating chamber cover, undoing the fixing screws, then clean the turbulators and internal fume pipes.

Also make sure to clean the fume extractor located under the chamber, accessed by removing the front door down the chamber.

Every 3-4 months clean the inside walls of the combustion chamber using suitable equipment (brushes) and replace the vermiculite wall if necessary.

Every 1800 hours of operation or 2000 Kg pellet, by means of a message 'SERVICE DUE', the stove signals the need for extraordinary maintenance (not under warranty) to be performed by qualified personnel who will carry out complete cleaning and reset the message.

Any knocking or forcing can damage the fume extractor, making it noisy during operation; therefore it is advisable to have this operation carried out by qualified personnel.

5.5 Cleaning the air flow meter

The air flow meter (it measures the flow of combustion air) installed inside the inlet pipe requires periodical internal cleaning every 3-4 months, using suitable equipment (blowing compressed air or suitable brushes).

5.6 Cleaning the ceramic surfaces (ceramic models)

The ceramic tiles are handicraft products and therefore may have minor surface imperfections such as tiny spots or slight colour differences. It is advisable to use a soft dry cloth to clean the ceramic surfaces; the use of detergents could highlight any flaws.

5.7 Cleaning the flue - flue connection

The flue connection must be cleaned at least once a year or whenever necessary.

Cleaning requires the suction and removal of the residuals in all the vertical and horizontal sections as well as the bends from the stove to the flue.

It is advisable to also clean the flue every year, to ensure correct and safe evacuation of fumes.

5.8 Cleaning the exchangers with turbulator-shaker device

The fume ducts inside the heating chamber must be cleaned at least once a day by operating the two knobs repeatedly with an upward and downward movement after opening the sliding cover.

Carry out this operation with the stove off and cold.
