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.ROCK

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. 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 and positioned so as not to be accidentally obstructed;

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). Floor protection base Wall air inlet min. 100 cm² A = 200 mm B = 200 mm C = 1000 mm D = 200 mm Antiwind grille Flue Inspection door on flue T union with inspection cap Flue connectionROCK

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.

Fumes can be exhausted through a connection to a conventional flue. - 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.

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 ).ROCK

The pellet stove has an internal heating water 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. 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 ‘Q055’ for management of commands as well as possible software upgrading. 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.

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.ROCK

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

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'.

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).

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. Connection to an external thermostat and/or chronothermostat is possible for detecting the temperature in a different place from where the stove is installed. For safe and reliable use: - when lighting and using the stove the first time, unpleasant odours may be created, therefore air the room thoroughly; - the hopper must only be filled with 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 stove must not be used as a waste incinerator; - the stove must only operate with the fire door always closed. - the fire door seals must be checked periodically to prevent air from entering; - to guarantee efficient performance and correct operation it is necessary to carry out periodical cleaning of 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 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.

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 control device has a lithium battery mod. CR2032 of 3 Volt inside. It allows the internal clock with own autonomy; if the clock signal does not appear when the stove is off or when switching the stove again a series of “0000” appears, it means it has to be substituted and you need to call one of our service point authorised for its substitution.

4.6.3 Menu 03 – Enable chrono

Allows all chronothermostat functions to be enabled/disabled. Regarding the selection and entering of times, use the six buttons, following the table in par. 4.2. It allows to enable and disable all the thermostat functions programmed; with the set ON you activate this function and it appears the led [ D ] related to it. When the daily, weekly, or week-end program is set you can see on the upper right side of the display it appears the led [C].

By accessing the submenu: DAY PROGRAM, the daily chronothermostat functions can be enabled/disabled and set. It is possible to set two operation phases delimited by the times set according to the following table where the OFF setting tells the clock to ignore the command.

By accessing the submenu: WEEK PROGRAM it is possible to enable/disable and set the weekly chronothermostat functions. The weekly programmer has 4 independent programmes whose final effect consists of a combination of the 4 programmings. The weekly programmer can be activated/deactivated; also, by setting OFF in the times field, the clock ignores the corresponding command. Carry out programming making sure not to overlap the hours of activation and/or deactivation on the same day in different programmes.

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. In order to avoid unwanted start and shutdown operations, activate only one programme at a time. Deactivate the daily programme if the weekly programme is required; with this setting it is advisable to deactivate the week-end programme.

4.6.4 Menu 04 – Select language

With this selection it is possible to select the dialogue language from those available entered in the menu, and namely: - ITALIAN - FRENCH - ENGLISH - GERMAN - SPANISH

By selecting ON in STANDBY mode the corresponding symbol on the display lights up and the stove shuts down automatically when the room temperature T has reached the set value (Tset + ΔT) 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 and precisely (Tset - ΔT) where ΔT 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. If the installation involves the use of a hot water tank, the standby mode is restricted to ON, and cannot be disabled.

4.6.6 Menu 06 – Buzzer

With this selection it is possible to activate/deactivate stove acoustic signalling.

4.6.7 Menu 07 – Initial loading

The setting of LOAD INITIAL allows pellet preloading for a time equal to 90 sec. with the stove off or cold. It is started with the button P1 and stopped with the button P4.

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.

4.6.9 Menu 09 – 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:

P1 and P3: Buttons to set the power level

P5 - COMFORT function: pressing this button forces power and ventilation onto P1. Deactivating this function will take the power and ventilation to the value prior to activation. This function observes and performs STANDBY. For the HYDRO versions, the COMFORT function only reduces the power to P1. P6 - QUICK function: pressing this button forces the machine power onto P5, saving the previous set power. Ventilation, too, if present, is forced onto AUTOMATIC (so maximum ventilation); saving the previous ventilation value. When pressed with the comfort function activated, it restores power and ventilation to the previous saved value. With set ambient or set water satisfied the heater modulates P1 power together with ventilation. P7 - MAGIC CLEANING function: pressing this button while the machine is working will force BRAZIER CLEANING. When OFF, activating this function will put the machine into FINAL CLEANING. From the state of FINAL CLEANING, if this button is pressed again it will discharge the FINAL CLEANING timer thus leaving intact the safety checks on the flue gas temperature. P8 - TURBO function: like the QUICK function with the difference that the heater does not modulate P1 power with set ambient or set water satisfied but modulates only in the flue gas safety condition.

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;ROCK

The unit controls the room temperature by means of its own digital thermostat whose function is to detect the temperature through a probe and lower the heat output when the set temperature is reached.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 panelling to access the electronic controller; - referring to the wiring diagram, connect the two thermostat wires to the respective board TERM terminals; - refit everything and check correct operation. The setting procedure is as follows: - external thermostat: SET the room temperature to 7°C; - external chronothermostat: SET the room temperature to 7°C and disable the chrono functions from the menu 03-01. 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

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.ROCK

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. Carry out this operation with the stove off and cold

RH - LH control knobs of the turbulator- shaker device in heating stove operation low position.ROCK

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.
