The pellet stoves work exclusively on pellets in different types of wood complying with Standard DIN plus 51731 or UNI EN 17225-2 or Ö-Norm M 7135 or having the following characteristics: Heat value: min. 4.8 kWh/kg (4180 kcal/kg) Density: 680-720 kg Moisture: max. 10% weight Diameter: 6 +0.5 m Ash percentage max. 1.5% weight Length: min. 6 mm- max. 30 mm Composition: 100% untreated wood from the wood industry or post consumer without added binding substances or bark, complying with current regulations Packing : in bags made from environmentally friendly or biodegradable material or paper

The pellet hopper is at the back of the stove. The door is located in the top part and loading occurs manually with the stove on or off, making sure not to overfill and operate in complete safety. The use of pellets with characteristics different from those tested by the technician during first lighting involves a new setting of the boiler pellet loading parameters; this operation is not covered by the warranty. Store the pellets in a dry place. For reasons of regular and efficient operation, pellets or other fuels cannot be manually loaded in the brazier. Do not load non-conforming fuels in the hopper. Do not load foreign bodies such as containers, boxes, bags, metals, etc., in the hopper. The use of poor quality and non-conforming pellets damages and compromises stove operation, invalidating the warranty with the exclusion of liability of the manufacturer.

Only use original replacement parts.

2 TRANSPORT AND INSTALLATION

2.1 Packing, handling, shipment and transport

The stove complete with packing can be lifted using a lift truck, inserting the forks (of suitable length) in the special spaces in the wooden pallet. Make sure the equipment used for lifting and transport can take the weight of the stove, specified on the dataplate and in this manual. Avoid taking the load in areas where it could be a danger if dropped. Open the packing, remove the stove from the pallet and position it in the required place, making sure it complies with that provided for, following the illustrations on the following pages. Set the stove down on the floor carefully without bumping and position it in the required place. Make sure the floor can take the weight of the stove, otherwise consult a specialised technician. Disposal or recycling of the packing must be carried out by the end-user in compliance with the current local regulations.

2.2 Place of installation, positioning and fire-prevention safety

The place of installation must be sufficiently ventilated to allow the removal of any combustion smoke leaks. The unit is suitable for operation in domestic environments with min. temperature of 0°C; it comes complete with an antifreeze function that activates the heating pump for system water temperatures below 6°C, safeguarding: the heating chamber, heating/DHW circuit. The antifreeze function is active only when the stove is electrically powered. To prevent the risk of fire, the structures surrounding the stove must be protected from the heat. For example, floors in wood or flammable material must be suitably protected with steel panels or toughened glass. Any wooden boards or beams above or crossed by the flue must be suitably protected in conformity with the requirements of the specific current installation standards. Suitable fire-prevention devices should be arranged for any eventuality.38 AT 18 The minimum front distance for the protection of flammable objects is 1 m.The minimum safety distances from flammable materials must be at least 0.2 m and in any case comply with the following table:

Every installation must provide for an easily accessible technical space for periodical maintenance. The stove is provided with 4 adjustable feet to facilitate positioning on not perfectly flat floors. To adjust the height, tilt the stove slightly and turn the feet as required. The stove is supplied with the ambient sensor fixed through a wrapper on the back of the stove; we recommend to remove the wrapper and to locate the sensor in the best position possible as to improve the temperature registration in accordance with the ambient context and the length of the cable. As for temperature registration done at a certain distance we reccomend to install the ambient thermostat/ambient programming clock-thermostat – see. par.4.8. The stove cannot be installed in bedrooms, bathrooms and in general in rooms where another heating unit is already installed without an independent air inflow. With wooden floors, install a floor protection base in conformity with the current regulations. Suitable fire-prevention devices should be arranged for any eventuality. Do not install the stove in places with an explosive atmosphere.

The stove air inlet pipe or intake is located at the back and is round and 50 mm in diameter. A quantity of air at least equal to that necessary for combustion must flow in the room where the stove is installed; therefore the combustion air necessary to ensure correct operation of the stove must be drawn:

from the room, provided there is a wall air inlet near the stove, communicating with the outside and of minimum area 100 cm² suitably protected externally by a grille;

or with direct connection to the outside with an appropriate pipe having a minimum internal diameter of 50 mm and maximum length of 1.5 m, provided with antiwind protection at the end (down bend). The air inflow can also be obtained from a room adjoining that of installation, provided the flow can occur freely through permanent openings to the outside; the room must not be used as a garage, for storing combustible materials or for activities with fire risk.

The fumes can be exhausted through a connection to a conventional flue or an external duct with double wall or insulated pipe.The fume exhaust connections must guarantee a minimum draught of 10 Pa so that the evacuation of fumes is assured in case of a temporary power failure. - The installer must check the efficiency and state of the flue and its conformity with the local, national and European regulations. - Certified pipes and connections with adequate seals guaranteeing their tightness must be used. - In case of fire, shut down the stove, promptly call the fire department, and avoid continual attempts to extinguish it. - Clean the flue and respective connection at least once a year.

2.4.1 Types of installation

Listed below are definitions and requirements for correct installation of an exhaust flue in accordance with Italian Standard UNI10683: FLUE : a vertical duct for collecting and expelling, at an appropriate height from ground, the fumes coming from a single unit and, where permitted, more than than one. FLUE technical requirements :- it must be fumetight, isolated and insulated depending on its use; - it must have a mainly vertical path with axis deviation < 45°; - it must be at a suitable distance from flammable materials with insulation or air gap; - it must preferably have a constant, free and independent round internal section; - it is advisable for the flue to have an inspectionable chamber for the collection of solid materials - and any condensate, placed under the beginning of the fume duct. FLUE CONNECTION or DUCT: duct or connection element between the unit and flue for evacuation of fumes. DUCT technical requirements: - it must not cross rooms in which the installation of combustion units is not allowed; - flexible metal tubes or fibre cement pipes are prohibited; - the use of counter-sloping elements is prohibited; - horizontal sections must have an upward slope of at least 3°; - the length of the horizontal section must be minimal and not more than 3 m; - there must not be more than 3 changes of direction, without the T union; - with change of direction > 90° a max. of 2 bends can be used with length in horizontal projection not exceeding 2 m - the fume duct must have a constant section and allow the recovery of soot. CHIMNEY CAP: a device placed on the top of the flue to facilitate the dispersion of fumes into the atmosphere. CHIMNEY CAP technical requirements: - it must have a section equivalent to that of the flue; - it must have a useful section not less than double the internal section of the flue; - it must prevent the entry of rain and foreign bodies and ensure the discharge of fumes in any atmospheric condition; - it must ensure an adequate dilution of fumes and be positioned outside the backflow area; - it must be without mechanical means of suction. The direct discharge of fumes must take place on the roof and not towards closed spaces ( even open air ).

2.5 Turbulator and baffle position check

Before lighting the stove make sure the brazier is in the correct position, i.e. fitted in the special slots. Also make sure the turbulator shaker device is resting in a lower position. An incorrect position of the brazier and/or turbulators can result in malfunctioning and excessive blackening of the glass. At every stove lighting check the correct position of the brazier and turbulator shaker device.

2.6 Electrical connection

Connect one end of the power cable to the rear socket of the stove, and the other to the wall socket. The voltage supplied by the system must match that specified on the stove dataplate and in the technical data section of this manual. Plug the device power cord must be connected only AFTER the end of the installation and assembly of the device and must remain accessible. During stove idle periods it is advisable to remove the power cable. Make sure the electrical system is equipped with an earth and differential switch in accordance with the current Regulations. The power cable must never touch the stove exhaust pipe.

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.41 AT 18

After carrying out the plumbing connections, it is possible to FILL the unit and system: - open all the air vent valves of the radiators - manifolds - boiler and system; - open the valve three-way motorized heating sanitary through lever A; - open the water filling cock gradually, making sure the vent valves work properly; - fill the system slowly, to allow proper and complete evacuation of the air from the vent, bringing the circuit under pressure (for a closed vessel system from 1.1 to 1.5 bar); - when finished, close the filling cock and the valve three-way motorized through lever A; - make sure all vent valves have discharged the air from the system. - to display the boiler's water circuit pressure, just press the control panel button P5 for 3 seconds. The creation of a heating system with installation of the boiler must comply with all the applicable National, Regional, Provincial and Local regulations in the country where the system is installed.

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 suitable 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'.43 AT 18

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

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 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

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;

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°C44 AT 18 - 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.

- 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.

During normal operation in work mode, the 'BRAZIER CLEANING' mode is activated at fixed intervals for a set duration.

4.4.3 Water heater with storage tank

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.

4.4.4 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 70°C with minimum return temperature not lower than (50-55)°C in order to prevent condensation inside the chamber.

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.

At the end of the operation the message 'OFF' appears in the dialogue box. During the shutdown stage the stove cannot be restarted until the fume temperature has fallen below a set value for a fixed time, with the message 'WAITING COOL' appearing in the dialogue box. At the end of the operation, the message 'OFF' will appear in the dialog box.

Carry out programming making sure not to overlap the hours of activation and/or deactivation on the same day in different programs.

By accessing the submenu: WEEK-END PROGRAM it is possible to enable/disable and set the week-end (Saturday - Sunday) chronothermostat functions. Activate WEEK-END programming only after deactivating the weekly programming. To avoid unwanted startup and shutdown operations, only activate one program at a time. Deactivate the daily program if the weekly program is required; with this setting it is advisable to deactivate the week-end program.

4.6.2 Menu 02 – User adjustments

With this menu it is possible to do a number of settings as follows - Set clock Before operating with the stove, it is necessary to set the current time and date so that there is a reference for possible chrono programming. The electronic controller has a lithium battery, model CR2032 3 Volt, giving the internal clock an autonomy of more than 4-5 years; with the stove off, whenever the clock does not keep the time, or a series of zeros is displayed at restart, the battery must be replaced by calling an authorised service centre. - Standby mode On activating this function, the stove shuts down automatically after the water temperature has remained above the SET value for a fixed time. The next automatic relighting will be possible only when the temperature falls below the SET temperature by a given value entered in the parameters table. Manual commands from the control panel have priority over programming. With the selection OFF the stove does not activate the STANDBY mode and functions normally activating the MODULATION function when the temperature exceeds the SET value. - Initial load Setting this function allows activation of gearmotor operation, with the stove off or cold, for pellet preloading of 90 sec. It starts with button P1 and stops with button P4. - Pellet type With the function on, press the buttons P1 or P2 to increase or reduce pellet loading to optimise consumption and combustion, depending on the type of pellets used. - Initial load auger 2 Setting this function allows activation of gearmotor operation relevant to the supplementary hopper for a fixed time. It starts with button P1 and stops with button P4.

4.6.3 Menu 03 - User setting

This range can be set from a min. of 0.5°C to a max. of 20°C depending on the customer's needs and/or the type of system. - Boiler/Puffer Delta With this selection, it is possible to set: the range between the SET temperature and the actual stove relighting temperature. This range goes from a min. of 0.5°C to a max. of 20°C depending on the customer's needs and/or the type of system. - Pellet level With the selection set to ON, the no pellets signal can be managed with: - a message on the panel 'NO PELLETS'; - management of a supplementary pellet hopper (available on request). With the selection OFF, the possible supplementary hopper is disabled and no message appears on the panel.

- DHW control The selection ON allows to manage DHW from the storage tank or heat exchanger through the signal from the thermostat or flow switch. The selection EST allows domestic hot water to be controlled in the summer (with heating off), via the signal from probe. Selecting this item enables operation of just the DHW branch; standby is forced to ON and post-circulation follows that set in the menu M-6-9. The summer function can be displayed only if the menu M-6-8 is set to S-BOILER.

4.6.4 Menu 04 – stove status

With this selection it is possible to display the instantaneous stove status giving the operating status of the various devices connected to it; various pages placed in succession are available for monitoring.

4.6.5 Menu 05 – settings by technician

This selection is reserved for the authorised technician of the COLA service centre. Modification of the technical parameters of menu 09 must be done by authorised and competent personnel; any changes made at random can cause serious damage for which COLA declines any liability.

The remote control works with the settings made in the control panel and allows stove lighting-shutdown, and adjustment of the required output and temperature. Since this device transmits through an infrared diode, it must be pointed at the receiver unit in the control panel. The remote control allows the following operations:

4.7.1 Replacing the battery

The remote control (model with 6 button) is powered by a 3-volt CR2025 type battery (included) located in the bottom of the device. Also remove the insulation before use. For its insertion and possible replacement, proceed as follows: - Operate the lever indicated; - Pull out the battery tray and replace the battery (3-volt CR2025 model) respecting the polarity; - Insert the tray; - Check proper functioning.

- Keep the remote control away from direct heat sources and water. - The remote control battery must be replaced and disposed of safely in compliance with local regulations;

To use an external thermostat, contact an authorised technician and proceed as follows: - turn off the power by means of the main switch on the back and detach the power cable; - remove the side panel to access the electronic controller; - referring to the wiring diagram, connect the two wires of thermostat to the respective board TERM terminals; - refit everything and check correct operation. The setting procedure is as follows: - external thermostat: SET in the menu M-6-7 in T-AMBIEN; - external chronothermostat: SET in the menu M-6-7 in T-AMBIEN and disable the chrono functions from the menu 01-01. All the menu functions do not change for each of the settings and signalling of the connection occurs with lighting up of the segment LED on the status bar of 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. 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 Brazier

Heating chamber tube bundle

Manifold – fume extractor

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.

The brazier must rest on the brazier holder and precisely on the entire ring band without air gaps.52 AT 18

5.2 Cleaning the ash container

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, the heating chamber cover and the bottom inspection door, undoing the relevant fixing screws, then clean the turbulators and internal fume pipes. Also, make sure to clean the fume extractor located under the bottom fume manifold accessed through the inspection door opening. Every 3-4 months clean the inside walls (insulating-refractory) 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

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. Carry out this operation with the stove off and cold.

Operations on the internal parts of the stove must be carried out by qualified personnel. Contact the nearest authorised service centre. Make sure the stove is unplugged and cold before carrying out any work on it.

Hot water tank cleaning (to be carried out every 2-3 years, depending on water aggressiveness)

• Remove the front panel of the hot water tank.

• Close the hot water tank on-off valves and open the drain cock.

• After draining, remove the inspection flange and carry out cleaning. Use specific products available on the market. Do not use metal tools to remove the scale.

• After cleaning, refit the inspection flange and hot water tank front panel and open the on-off valves. Magnesium anode The degree of deterioration of the magnesium anode can be checked directly from the outside by unscrewing it from the hot water tank flange (after turning off the domestic hot water supply and draining the hot water tank). This check is advisable at least once a year.

• Check the magnesium anode and replace it if necessary. If the water is very hard, above 20 degrees French, install a water softener in the system. BIf water softeners are installed at the boiler cold water inlet, make sure not to reduce the water hardness too much,as this could cause early deterioration of the magnesium anode in the hot water tank.
