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 water circuit complete with circulating pump, safety valve, 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.

To connect the heating stove to a DHW 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. For the connection to the DHW circuit it is necessary to install a monostable 3-way valve outside the stove whereas the circuit is not functional with the DHW pump.

To connect the DHW system 3-way solenoid valve it is necessary to request the optional: supplementary electronic board model 'O074' for management of commands.

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.

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.
• 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 with a black arrow pointing to a button, 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 heat from a wood flame with the convenience of automatic management of temperature and the possibility of weekly programming of lighting and shutdown.

For safe and reliable use, observe the following:

• when lighting the stove the first time, unpleasant odours may be created, therefore ensure good ventilation of the room, especially during the first period of operation;
• the hopper must only be filled with pellets, without allowing the bag to come into contact with the hot surfaces of the stove;
• do not put any type of fuel other than recommended wood pellets in the hopper;
• the unit must not be used as a waste incinerator;
• the stove must work only with the fire door always closed;
• the fire door seals should be checked periodically to ensure air tightness;
• to ensure efficient and correct operation, it is necessary to clean the brazier whenever pellets are loaded;
• when lighting the stove for the first time, make sure to allow it to get hot gradually without overheating;
• during lighting, operation and shutdown, the stove may creak a little due to the heat expansion.

4.2 Control panel

The control of the stove occurs through the use of a control panel provided with four buttons and an LCD display. The panel allows activation and deactivation, adjustment during operation and the setting of management programs and maintenance.

4.3 Lighting

Before lighting of the stove, check the following points:

• make sure to have read and understood the instructions in the manual;
  – the hopper must be filled with pellets;
  – the combustion chamber must be clean;
• the brazier must be completely free, clean of any combustion residuals and properly positioned in the brazier holder;
  – check the hermetic closure of the fire door and ash drawer;

• At first lighting, remove from the stove firebox and glass any components which could burn (instructions/label).
• Any lightings done after long idle periods require complete cleaning of the combustion chamber and the removal of any pellets left in the hopper, in being damp fuel no longer suitable for combustion.

To light the stove, press button P4 on the panel for a few seconds. The message START will appear on the LCD display. This phase is automatic and is managed completely by the electronic control, without any possibility to intervene on the parameters.

The stove carries out the startup phases in sequence according to the procedure defined by the parameters, reaching the work condition. After a certain time, if the fume temperature has not reached the minimum permissible value, the stove goes in alarm status.

4.8 Installation procedure

The stove installation procedure depends on the type of water system it is connected to. It can also differ depending on the use of an external thermostat or the internal probe.

For the correct electrical and water connections, contact a specialised technician.

4.9 Idle period (end of season)

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

• remove all the pellets from the hopper;
• disconnect the power and remove the power cable;
• 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.

Parts / Period Type of cleaning	1 day routine cleaning	2-3 days routine cleaning	1 month routine cleaning	2-3 months routine cleaning	1 year extraordinary cleaning: carried out by the Service Centre

Ash compartment-pan		■
Door glass		■
Heating chamber tube bundle			■		■
Manifold – fume extractor				■	■
Glass - door seal					■
Pipe - flue connection					■

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.
