1.9 Stove decommissioning

When definitively deciding to not to use the stove any more, we recommend to disconnect the power supply and to empty the pallet tank completely. In order to eliminate the stove, it is necessary to packaged it with a strong packaging and then take contact with local organisation which follows the selling off operations respecting the local rules. Otherwise we recommend to back the stove directly to the distributor when buying a similar new one.

1.10 Instructions for requesting assistance and replacement parts

To request any assistance and/or replacement parts contact your dealer, area importer or the nearest authorised service centre, clearly specifying the following: stove model, serial number, date of purchase, list of replacement parts, details of faults or malfunctioning. - All operations on components must be carried out by authorised and/or qualified personnel. - Make sure all electrical connections are disconnected and that the stove is cold before any work on it. - Only use original replacement parts.

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. 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 not below 0°C. To prevent the risk of fire, the structures surrounding the stove must be protected from the heat. Floors in wood or in any flammable material must be suitably protected at the base with steel or toughened glass panels; the protection must cover the base and also a certain area in front of the stove. 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. The minimum front distance for the protection of flammable objects is 1.5 m. The minimum safety distances from flammable materials must comply with the following table:33 LIRA 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.

2.4.1Types 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 Brazier 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 top smoke baffle is properly fitted. A wrongly positioned baffle can result in malfunctioning and excessive blackening of the glass. At every stove lighting, check the correct position of the brazier on the brazier holder.

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. 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.

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.36 LIRA 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 'AL 8 NO NEG PRESS' or 'AL 9 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 - pellet hopper temperature safety thermostat

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

In case of brief power failures, the stove relights automatically. 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 Fume extractor fan failure

If the fume extractor fan stops for any reason, the electronic controller instantly stops the pellet feed, displaying the message 'AL 4 FAN FAIL'.

A temperature probe is connected to a safety thermostat above the pellet chute which automatically interrupts the pellet supply in case of excessive heating > 85°C. 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, after unscrewing the protection cap (figure opposite). Restart the stove normally.37 LIRA 4 STOVE USE

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.

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. Given below is the control panel and the main functions of the buttons: LCD display P1: Button for setting the room temperature and scrolling the various menus P4: On/Off button and for exiting the MENU

P2: Button for setting the power and scrolling the various menus

Indication of activated functions

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. - Do not use flammable liquids to light the unit. - In case of persistent failed lighting, contact the Service Centre.38 LIRA

After the startup phase, the stove goes to WORK mode, which is normal operation. The heating power can be adjusted by pressing button P2 and then buttons P1 and P2 from the maximum value of 5 to a minimum value of 1. The stove automatically adjusts the ventilation of hot air according to the set power. In addition to the power, also the room temperature can be adjusted. Press button P1 and with buttons P1 and P2 make the desired setting, from a maximum value of 40 °C to a minimum value of 7 °C. - Make sure to check the pellet level in the hopper so that the flame does not go out due to lack of fuel. - Make sure the unit is off when loading pellets. - The pellet hopper cover must always remain closed, to be opened only during fuel loading. - The bags of pellets must be kept at least 1.5 m away from the stove. When the SET temperature is reached, the corresponding symbol lights up on the display. If STANDBY mode is activated, the stove shuts down after a delay of several minutes. Restart occurs after the room temperature falls below the set value by a few degrees (default 2 °C). If STANDBY mode is not activated, or if the fume temperature has reached the set maximum value, the LCD display shows the message MODULATE and the stove activates the flame modulation without any intervention by the user. If the temperature increases again, above a set limit, the HOT FUMES alarm 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 fixed duration of several seconds.

To turn off the stove, press button P4 for a few seconds. The auger is immediately stopped and the fume exhaust fan goes to high speed, with the message FINAL CLEANING appearing on the display. The fume exhaust and air ventilation motors will remain on until the stove temperature has fallen sufficiently. At the end of the operation the message OFF will appear on the display. During the shutdown phase the stove cannot be restarted until the fume temperature has dropped below a fixed value for a given time. If the activation button is pressed the message WAITING COOL will be displayed.

Press button P3 to access the menu. It is divided into eleven sub-menus for accessing the settings of the electronic control. The various sub-menus can be scrolled by pressing buttons P1 and P2, and can be accessed by pressing button P3 and exited by pressing P4.

Access the third sub-menu WEEK PROGRAM to enable, disable and set the functions of the weekly chrono. Follow the same procedures of the previous paragraph. Up to four operation phases delimited by the set times and days can be set.39 LIRA Do the programming carefully, without overlapping the activation and/or deactivation times on the same day in different programs. Access the fourth sub-men WEEKEND PROGRAM to enable, disable and set the chrono functions for the weekend. Follow the same procedures of the previous paragraph. Up to two operation phases delimited by the set times can be set. To avoid unwanted startup and shutdown operations, activate only one program at a time.

Access the fifth sub-menu to exit the chrono menu and access the main one.

4.6.4 Menu 04 – select language

With this selection it is possible to set the desired language from those available.

4.6.5 Menu 05 – standby mode

By selecting ON in STANDBY mode the corresponding symbol on the display lights up and the stove shuts down automatically when the room temperature has reached the set value for a given time. The next restart in automatic will be possible only when the room temperature falls below the set value by a few degrees (default 2°C). With the OFF selection, the modulation function is active but not the STANDBY mode. Therefore when the temperature exceeds the set value the stove will operate at minimum power.

4.6.6 Menu 06 – buzzer

With this selection it is possible to activate or deactivate the stove alarm buzzer.

4.6.7 Menu 07 – initial loading

Allows the preloading of pellets for a given time. This function can only be activated when the stove is off and cold and is used if the auger is empty due to no more pellets. It is started with button P1 and stops with button P4.

4.6.8 Menu 08 – stove status

This selection is reserved exclusively for the authorised COLA service centre technician.

4.6.9 Menu 09 – settings by technician

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

4.6.10 Menu 10 – settings by technician

This selection is reserved exclusively for the authorised COLA service centre technician.

4.6.11 Menu 11 – ECO mode

The selection ON in the ECO mode limits the stove to operate in modulation, i.e. at minimum power and minimum ventilation. The display shows NIGHT ECO and the corresponding symbol lights up.

The remote control is a device that transmits through an infrared diode. Therefore it must be pointed towards the receiver unit fitted in the control panel. The remote control allows the following operations:40 LIRA P1 and P3: Buttons to set the power level

4.7.1 Replacing the battery

The remote control is powered by a 3-volt CR2025 type battery located in the bottom of the device. 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;

The standard unit controls the room temperature by means of a digital probe that adjusts the power according to the set temperature. To use an additional thermostat, contact an authorised technician and proceed as follows: turn off the power at the main switch (if available) and disconnect the power cable; remove the panels to gain access to the main board; referring to the wiring diagram, connect the two thermostat wires to the respective terminals TERM on the board (use a 'normally open' type thermostat); refit everything and check proper functioning Then set as follows: − external thermostat: set a temperature of 7°C; − external chronothermostat: set a temperature of 7°C, disable the chrono functionality in the menu 03 and set the STANDBY function to ON. When the set temperature is reached, the stove will shut down and not go to modulation. In this case, however, it is advisable to use the stove time programming function and only the external chronothermostat set temperature function. In fact, only with this joint setting is it possible to set STANDBY to ON or OFF, obtaining respectively modulation or shutdown when the SET temperature is reached and likewise obtaining shutdown and lighting according to the set time programming. When the external thermostat requests stove operation, the corresponding symbol will light up on the display.41 LIRA

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 ensure correct operation and 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

year extraordinary cleaning: carried out by the Service Centre Brazier

Baffle - fume exchanger

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

5.3 Cleaning the glass and air slots

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 the inner side of the glass.

The brazier must rest on the brazier holder and precisely on the entire ring band without air gaps.42 LIRA

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 baffles and flueways. To do this, remove the cover and the top front panel of the stove. Remove the cast iron exchanger by undoing the fixing screws then clean the baffles and the chamber. Also make sure to clean the fume extractor located under the chamber, accessed by removing the inspection port located on the front lower part of chamber. Every 3-4 months clean the inside walls (insulating-refractory) of the combustion chamber using suitable equipment (brushes) and replace them if necessary. Every 1800 hours of operation, 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 depending on stove use and the type of installation. 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. For any maintenance or end of season cleaning, COLA recommends contacting an authorised service centre, which will also check the wear on the stove's internal components.

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.43 LIRA
