1. FIVE BASIC RULES FOR INSTALLATION

1.1.

SUITABILITY OF THE ENVIRONMENT

1.2. AIR INLET

1.3. SMOKE UNION

1.4. FLUE PIPE

1.5. CHIMNEY

An open fireplace consumes ~45m3 of air per kg of fuel.

The installation environment must ensure as much air as the appliance can consume.

Refer to the manufacturer's technical data concerning fuel consumption to determine the minimum size of the installation environment.

Adhere to the safety distances specified by the manufacturer for walls and/ or flammable surfaces.

Maintain the safety distances from furniture and other furnishing items that may be damaged by the heat.

Insulate smoke ducts positioned close to flammable materials.

Installation is not permitted in rooms already containing a type-A or ventilation hood appliance.

This is obligatory to ensure a correct flow of air to reintegrate the oxygen consumed by the appliance in the installation environment.

It is important to create an air inlet leading directly to the external environment.

Size the air inlet correctly, according to the dimensions specified by the manufacturer.

The air inlet performs two functions:

It provides sufficient air intake to allow the product to operate correctly.

It provides air in the environment to compensate the air consumed by combustion.

The smoke connection is the piece of pipework that connects the flue pipe to the appliance. This connection must adhere to fundamental safety and heat resistance requirements.

The use of flexible pipes is not permitted. Therefore the connection can be constructed using only rigid pipes made from:

 stainless steel or  aluminised steel.

Forced outlet products must be connected using airtight pipes fitted with suitable sealing.

When connecting closed fireplaces only use changes of direction with a maximum inclination of 45°.

Use a maximum of three 90° bends for pellet stoves.

The connection must NEVER be smaller in size at the smoke outlet of the appliance.

The flue pipe is a vital element for the discharge of smoke and should therefore:

Be waterproof and thermally insulated.

Be made of suitable heat-proof materials that are resistant to the effects of combustion products and any possible condensation.

Have a vertical arrangement with deviations from the axis of no more than 45° and without kinks.

Must discharge the smoke at the highest point of the home.

Comply with the requisites specified in the technical table, such as the internal crosssection of the chimney and the height.

Have an internal section which is preferably circular.

Be cleaned if preexisting and has previously operated.

Wall outlets are forbidden for pellet stoves.

The chimney is the end part of the flue pipe. Correct draught for the flue pipe depends on the chimney.

The chimney must: Have an inner

section equal to that of the flue pipe.

Have a outlet section of at least double that of the inner section of the flue pipe.

Be built in such a way as to prevent rain, snow and any foreign bodies from penetrating the flue pipe.

Be positioned so as to ensure adequate dispersion of smoke and, in all cases, outside the reflux area in which backpressures are likely to form.

2. Combustion control

2.1. The RED recipes

RECIPES are preset programmes stored on the appliance mother board. These recipes contain a series of parameters concerning the operation of the stove in all its modes. Recipes contain, first and foremost, the values relating to the start-up and shutdown times of the geared motor and the number of revolutions at which the smoke blower fan needs to operate at the various heat outputs. The concept used to create recipes involves varying the intake of fuel that falls into the brazier, depending on the quality of the flame.

2.2. Combustion control

To be certain that the correct recipe has been created, switch on the appliance and check the combustion when the flame is stable and regular.

The flame must be yellow on the sides and white in the centre. It should not be excessively slow nor too oxygenated. The top of the flame must be aspirated towards the top part of the combustion chamber and must always remain within the outline of the brazier and not overflow to the sides. The bottom must almost always be visible, given that the whole of the pellets that fall during a cycle of the geared motor burn fully before the final load cycle. The flame must also "pulse" (move up and down) as pellets are burnt immediately when loaded.

CORRECT FLAME

IRREGULAR FLAME

2.3. Modify the recipe after the combustion control. A flame that is too oxygenated is low, very white and "nervous" and the embers of the pellet tend to overflow the

brazier. The most obvious fault is a flame that is always low and a tendency of the fire to go out, particularly at low outputs.

The variations to make are as follows:

 Increase the quantity of pellets falling into the brazier (by percentage)

A flame that is not very oxygenated is orange, weak and tends to produce puffs of smoke. The glass and the

ALUTEC® (white interior refractory material) get dirty and blacken quickly. The most obvious fault is an accumulation of pellets inside the brazier. The faster the accumulation time, the greater the variations that must be made to the recipe.

The variations to make are as follows:

 Decrease the quantity of pellets falling into the brazier (by percentage)

POSSIBLE OTHER SOLUTIONS TO THE CALIBRATION PROBLEM:

If the problem persists carefully check that the seals on the door and ash drawer are working correctly, that all of the cleaning caps on the combustion chamber are closed and that there are no obstructions in the flue pipe.

Remember that the quality of the pellets is fundamental for correct combustion and is a basic rule for the combustion described above.

3. RED AIR and MULTIAIR stoves

3.1. Interpretation of installation

One of the first actions to carry out to select the correct combustion parameters for our stove is to identify and understand whether the installation that you are carrying out (or find yourself dealing with) presents any difficulties with regard to evacuating exhaust smoke. Therefore, we have divided the installation types into three large macro categories:

 ACTIVE, meaning that the smoke connection is very short, free or almost free of bends and allows almost

direct connection in an "active" flue pipe; in other words, a flue pipe with a minimum natural draught of 0.10 mbar when warm.

These types of installation do not usually require additional adjustments as the basic recipe that the stove leaves the manufacturer with has been designed for installation using a flue pipe with a minimum natural draught of 0.10 mbar, as indicated in the use and installation manual of the product.

 PASSIVE, meaning that the smoke connection is more winding as it has bends and/ or a few metres of

pipework. If you are carrying out (or find yourself dealing with) an installation of this type, remember that there are maximum parameters to adhere to. The stove is not guaranteed to operate if these parameters are exceeded. For this type of installation:

o Never include more that three 90° bends. o Never include more that three metres of Ø 80 mm horizontal pipework. This pipework must have a

minimum gradient of 3-5%.

o Never use counter-sloping pipes (pointing downwards). o Never create a connection with more that six metres of Ø 80 mm pipework. o Always install an inspection "T" at the outlet of the appliance (avoid 90° and 45° bends).

 “WALL” installations (forbidden in Italy, Germany, Austria and Switzerland according to current laws but

permitted in some European countries) carry a high degree of risk. If you decide to use this type of installation we recommend that you adhere to the following:

o Protect the outlet of the pipework from the wind as effectively as possible. o ALWAYS use a windproof chimney (preferably one of high quality, not restricting the installation

to a simple windproof cap for boilers).

o Do not use 90° or "T" bends instead of windproof chimneys. Usually these stratagems cause a

deterioration in operation.

o Always construct the shortest possible connection. o Avoid using sections of non-insulated, external pipework o Avoid vertical rises in pipework close to walls as the walls can become dirty. o Smoke discharge below balconies, terraces and eaves should be strictly avoided. You may think

that installing the discharge in these areas better protects the outlet from the wind but, in fact, the opposite is true. Wind nestles in these areas of the home and makes it difficult for smoke to exit. There is also a high risk of the building become very dirty.

N.B. The manufacturer bears no responsibility for malfunctions or damage to property and persons. An installation carried out in this manner may also invalidate the guarantee.

These types of installation normally require additional adjustments to modify either the fuel intake or the combustion air intake. To carry out these modifications follow the general concepts of observing the flame explained in the previous paragraph and the instructions given in the next chapter regarding the modification of pellet dosing and the speed of the smoke blower fan.

To further help you to identify the different types of installation, some examples are given below:

3.2. Recipe selection for AIR and MULTIAIR products

The recipe, and therefore the intake of fuel into the brazier, is modified as follows:

TYPE OF PANEL

INSTRUCTIONS

1. Press button E repeatedly until the led

corresponding to the variation that you wish to make lights up. Take into account that:

 LED -2 = -20% pellet  LED -1 = -10% pellet

 LED 0 = no variation from the standard.

 LED +1 = +10% pellet  LED +2 = +20% pellet

2. No confirmation is required as the led corresponding to the selection made will always remain lit during operation.

3.3. Modifying the speed of the smoke blower fan on AIR and MULTIAIR products

In addition to medicating the recipe, you can increase or reduce the power of the smoke blower in percentages (in the same way as for pellet loading) to modify or improve combustion. This modification is carried out as follows:

TYPE OF PANEL

INSTRUCTIONS

1. Press buttons E and D at the same time.

2. LED 0 will begin to flash. This means that the speed of the smoke blower fan (rather than the pellet dosage) can now be modified. If the pellets are modified the led remains lit with a fixed light (not flashing).

3. Press button E until the led corresponding to the

variation that you wish to make lights up. Take into account that:

 LED -2 = -20% rpm  LED -1 = -10% rpm

 LED 0 = no variation from the standard.

 LED +1 = +10% rpm  LED +2 = +20% rpm

4. No confirmation is required as the led corresponds to the selection made. Simply wait 5 seconds for the display to return to the initial status.

3.4. RED AIR and MULTIAIR stove settings

3.4.1. External room thermostat

An external room thermostat can be connected to all appliances. To do this, the two cables from the external thermostat must be connected directly to the motherboard. As the internal thermostat, (controlled by potentiometer B) cannot be deactivated, it must be set to the minimum, that is; turned fully to the left (as shown in the figure). In this way, the external thermostat will take control of the stove as the internal thermostat is adjusted to a very low temperature and therefore always satisfied (internal electronic contact always closed). All types of ON-OFF timed or room thermostat are compatible with RED appliances. Remember that using a simple ON-OFF thermostat will allow you to reduce the operating power of the stove to a minimum when the desired room temperature has been reached. If, on the other hand, you wish the appliance to switch off when the temperature is reached you MUST activate the ECO-STOP function, as described in the instructions given in the next paragraph.

CONTROL PANEL

INSTRUCTIONS

1. Connect the two cables to the board as shown in the figure

2. Rotate potentiometer B of the internal thermostat

fully to the left, in other words to the minimum possible temperature.

3. Adjust the desired temperature on the external thermostat.

If you wish the stove to switch off when it reaches the temperature activate the ECO-STOP function

3.4.2. ECO-STOP mode

This function can be considered an "advanced automatic" mode that prompts the appliance to switch off when the temperature is reached rather than simply reducing the minimum power (ECO). We recommend that you DO NOT use the ECO-STOP function in rooms with minimal insulation or if cooling in the installation room is

very sudden. If used in these conditions the appliance will be forced to switch on and off frequently, consequently degrading the igniter and/ or causing failed ignition as the ignition is carried out in a dirty combustion chamber and/ or brazier with obstructed holes.

TYPE OF PANEL

INSTRUCTIONS

ECO-STOP activation

1. Press ON/OFF button D five times in a row

within a 6 second time period

2. The board responds by sounding a long signal to

confirm (3 seconds).

To deactive ECO-STOP: as with activation, press the ON/OFF button briefly five times in a row within a 6 second time period. The board responds by sounding a long signal to confirm (4 seconds).

SERVICE MANUAL

Rev. 02

08/11 – M.C.

Service Manual – 8901118900 – EN

Other instructions for a full understanding of the ECO-STOP function and how the panel signals the various behaviours:

 When the temperature is satisfied (temperature sensor on the edge of the stove satisfied or external

thermostat, if present, satisfied (open contact)) the stove enters the Eco-Stop counting phase. This phase prompts the gradual passage from power 5 to power 1. The decrease in temperature lasts for one minute for each power to prevent the flame from descending too suddenly. When the first power level has been reached the appliance begins a countdown of 20 minutes. At the end of the countdown, if the temperature is still satisfied the appliance will begin to shut down. On the other hand, if during these 20 minutes the temperature once again becomes unsatisfactory for more than 10 seconds (to exclude a momentary indication), the count immediately zeros. If the temperature in the room has decreased the stove will return to maximum power. If the temperature has not decreased the stove will remain on minimum power and will restart the countdown to attempt a new shut down in ECO-STOP 20 minutes later.

 When shutting down via ECO-STOP, LED1 will flash every 2 seconds with an alternating orange and

green led

 When ECO-STOP puts the stove into stand-by mode LED1 will flash every 2 seconds with an alternating

orange and green led

 ECO-STOP switches the stove back on when both of the following conditions are present:

 At least 5 minutes have elapsed since the switch off process began;  The room temperature is at least 2 °C lower than the set temperature

(e.g.: if set to 20 °C, the stove restarts when the temperature drops below 18 °C)

 If operating with an external thermostat the contact of this thermostat will control the restart.  N.B.: to exclude a momentary indication, the aforementioned conditions must remain present for 10

consecutive seconds.

 When ECO-STOP switches the stove back on LED1 will flash green (as with normal ignition)  If the stove is switched off manually using the ON/OFF button with the ECO-STOP function active, ECO-

STOP will still be active the next time the stove is started up

 If there is a black-out while the stove is switched on or in stand-by mode with ECO-STOP active, when the

stove restarts ECO-STOP will switch it off and then on again (if the temperature is not satisfactory, with a delay of 120 seconds)

3.5. Signals during operation.

TYPE OF PANEL

LED 1

 Off: The stove is waiting to start up  Flashing green: Start up  Fixed green: Stove on at full power  Flashing orange: Shut down  Flashing red: Alarm in progress

 Fixed red: Stove switched off after alarm

If the stove switches off after a mains power failure led 1 continues to flash orange even after cooling.

4. RED HYDRO stoves and the COMPACT 24 boiler

Unlike pellet stoves designed to heat only air, Hydro pellet stoves and boilers have all the complexities of combining the appliance to an existing hydraulic system. Therefore, it is essential that these appliances are correctly installed by a specialised heating engineer who

can also calculate the heat requirement of the system.

These appliances are fitted with all the necessary operating and safety devices to apply it to a CLOSED VESSEL system and, therefore, can only operate when the pressure of the system is between 0.5 and 2.5 bar. The

recommended operating pressure is 1.0 bar when cold and/ or 1.5 bar when warm.

4.1. Adjusting the recipe in HYDRO stoves and in the COMPACT24

Unlike other air stoves, the HYDRO stove and boilers do not present any significant difficulties with regard to selecting the recipe as the power of the smoke blower fan and the high fuel load make adjusting the combustion much less delicate. To set the recipe just follow the simple instructions below. However, you should do this only if there are fuel accumulation faults or the flame is too low and weak, as explained in chapter 2. With regard to the COMPACT 24 boiler, the flame in the combustion chamber cannot be fully seen. There is only a small viewing window on the fire door to allow you to check whether there is a flame. Boilers, even more than stoves, require very little adjustment. Therefore, adjustments must only be made if the fuel is not compliant or the boiler output is low due to low/ excessive fuel intake.

Take great care not to overload the brazier. This would undoubtedly produce a better output but would also cause continuous overheating of the structure and therefore shorten the life of the product.

 With the stove is switched off, press buttons 

and  at the same time

 Select the recipe using buttons  or 

 Confirm the selection using button  , keeping it

held down until the word OFF appears on the display

The fuel load is adjusted by percentage. In other words, you can modify the pellet chute by percentage compared to the basic standard adjustment. The possible adjustments are:

-3 = -30% pellet

-2 = -20% pellet

-1 = -10% pellet

0 = standard adjustment by the manufacturer

+1 = + 5% +2 = +10% +3 = +15%

4.2. First ignition: what to check

 Always carry out a preventative check of the number of radiators and the system's potential absorption. Also

check the flow and return pipes, both in terms of the diameter and the insulation.

 The stove MUST be connected to the hydraulic system using flexible pipes and inserting cut-off cocks to

isolate the appliance should it require maintenance.

 Load the system with cold water using the associated filler cock located on the rear of the system or via

another filler cock on the system. Bring the pressure to 1.5 bar.

 The pressure of the system must be checked using an external pressure gauge that must be installed near to

the stove (recommended), using the gauge supplied (Compact 24) or a gauge already fitted on the system, for example the gauge already fitted on the gas boiler (if present)

 Check that there are no leaks from the hydraulic connections of the stove and the system. Tighten the

connections if necessary. The internal pipes are tightened dry and tested with compressed air at 4 bar. However, an additional check is essential when the system is filled with water and pressurised.

 Vent the air from the system of radiators via the associated valves.  Vent the stove via the relief valve underneath the ceramic/ steel top. If necessary, reintegrate the system to

bring the pressure to the recommended levels (1.5 bar).

 Check that the room sensor (located on the rear of the system) is not touching any hot parts and is in a

suspended position to detect the temperature of the room.

 Adjust the correct recipe according to procedure.  Check the calibration of the room temperature by pressing the SET button .

 Use buttons  and  to bring the temperature to the desired level. This must be a higher temperature than

that in the room to power the appliance.

 Check the calibration of the water temperature by pressing the SET button . Use buttons  and  to bring

the temperature to the desired level. This temperature must NEVER BE LOWER THAN 55 °C. Below this temperature significant production and condensation problems can occur. The recommended temperature is 65 °C.

 Start up the stove and wait for the water in the boiler to reach 50 °C. At this temperature the circulation pump

(water pump) begins to operate and the hot water begins to circulate in the system. When cold water returns to the boiler the water inside the boiler itself will rapidly drop in temperature and the circulation pump will stop. This is perfectly normal and can last 20 to 40 minutes, depending on the size of the system. When all the water inside the system reaches a temperature above 52 °C, the circulation pump will remain permanently active.

 You can adjust the temperature at which the pump intervenes by entering the technical parameters (see

chap. 6. ) and, more precisely, by modifying parameter PR 28. Use buttons  and  to modify the start up/ shut down temperature of the circulation pump. We recommend that you do not excessively lower the temperature (MIN 40 °C) or excessively exceed the threshold (MAX 55 °C).

4.2.1. Regular operation of HYDRO stoves and COMPACT24

Once the appliance reaches regular operation it autonomously selects the operating power according to the difference between the required and desired room and water temperatures. THE APPLIANCE OPERATES ONLY IN AUTOMATIC MODE (MANUAL mode does not exist) The flame begins to decrease its operating power 5 °C before reaching the temperature of the water in the boiler. This prevents the stove from exceeding the desired water temperature due to the thermal flywheel. The stove goes into ECO mode (minimum power) when one or both of the temperatures requested (water and air) have been satisfied.

UT18, follow the same procedure used to access UT19.This interval forces the stove to decrease the operating power if the water reaches the set temperature plus 10 °C. Example: SET WATER TEMPERATURE = 65 °C

TEMPERATURE DIFFERENTIAL = 10 °C At a temperature of 75 °C the stove is forced to go to minimum power to prevent the water from overheating and boiling.

4.4. Information about the operation of the appliance

You can retrieve information about the operation of the appliance while is it switched on or during some specific operating phases. This information is often fundamental to solving problems or correctly diagnosing operation and faults.

CONTROL PANEL

INSTRUCTIONS

Pressing and holding down button  will provide two

pieces of information:  The number of revolutions of the smoke blower

detected by the encoder (E.g.: 1840)

 The instant temperature of the smoke sensor (E.g.:

103°)

4.5. Shut down, recipe adjustment and bypassing the start-up phase

Should it be necessary to alter the recipe after observing the quality of the flame, remember that the appliance must be switched off. This is because the adjustment procedure can only be performed when the product is set to OFF, as illustrated previously, (chap. 4.1. ). Once the recipe has been modified, you must restart the stove and wait until the full start-up process has been completed and the product is operating (15 to 18 minutes) before checking whether the modifications to the recipe have had the desired effect. To avoid having to wait for the entire start-up process to finish you can skip the entire procedure, allowing you to check the new settings immediately. However, to carry out this operation you must ensure that:

 The flame is full before switching off the product. This ensures that you have the necessary time to carry

out adjustments before the flame extinguishes normally due to lack of fuel.

 The temperature sensor reads more than 60 °C  When restarted, the pellet in the chute feeds the flame or the embers that are still alive in the combustion

chamber. If these conditions are adhered to you can restart the product and skip the entire start-up phase, arriving immediately at the regular operation and flame checking phase.

5. RED pellet boilers: Practika 28-33 – Variomatic 33

Unlike Hydro stoves or the COMPACT24, these appliances are NOT fitted with all operating and safety devices (circulating pump, expansion vessel, safety valve, relief valve, etc.). These must be installed and sized by a specialised heating engineer who can also calculate the heat requirement of the system.

The creation and set up of the heating system is therefore subordinate to installation in compliance with the standards and laws of the installation country. These laws normally anticipate the issue of a statement of conformity and installation of the highest standard. Any installation not carried out in accordance with these

criteria may potentially cause malfunctions or damage to the product and the system as well as invalidating all guarantees. We recommend installing these products on a CLOSED VESSEL system given that the recommended operating pressure is 1.0 bar when cold and/ or 1.5 bar when warm. If installed with an OPEN VESSEL the minimum pressure required is 0.3 bar (3 metres of water column)

5.1. Adjusting the recipe in the boilers

The boilers do not present any difficulties in terms of adjusting combustion as the power and high fuel load make adjusting the combustion much less delicate. Boilers, even more than stoves, require very little adjustment. Therefore, adjustments must only be made if the fuel is not compliant or the boiler output is low due to low fuel intake.

Take great care not to overload the brazier. This would undoubtedly produce a better output but would also cause continuous overheating of the structure and therefore shorten the life of the product.

5.3. First ignition: what to check

 Wash the system prior to installation and put the system into operation  Always carry out a preventative check of the number of radiators and the system's potential absorption.  Check the flow and return pipes, both in terms of the diameter and the insulation.  Check that all the cut-off cocks of the system are open or that the thermostats that control the solenoids in the

area permit opening (heat requirement from the thermostat)

 The boiler must be connected to the hydraulic system, preferably using flexible pipes and inserting cut-off

cocks to isolate the appliance should it require maintenance.

 Load the system with cold water using a filler cock.  Bring the pressure to 1.5 bar.  The pressure of the system can be checked using the pressure gauge supplied or the gauge already fitted on

the system, for example the gauge already fitted on the gas boiler

 Check that there are no leaks from the hydraulic connections.  Check that the safety valve of the system is connected to a sewer drain.

 Vent the air from the circuit using the associated valves that should be located along the system.  If there is an external thermostat ensure that it is correctly connected to the boiler.  Check the calibration of the water temperature in the boiler as indicated below:

 Switch on the boiler and wait for the water in the boiler to arrive at the temperature set for activation of the

pump (standard 50 °C, can be modified in the associated menu). At this temperature the circulation pump (water pump) begins to operate and the hot water begins to circulate in the system. When cold water from the system returns to the boiler the temperature inside the boiler itself will rapidly drop and the circulation pump will stop. This is perfectly normal and can last several minutes, depending on the size of the system. When all the water inside the system reaches a temperature above the set value, the circulation pump will remain permanently active. In the time interval before the pump activation temperature is reached, the pump will switch on for 10 seconds every minute to mix the water inside the system. As mentioned above, you can modify the temperature at which the pump intervenes by entering the setting menu:

5.3.1. External room thermostat

An external room thermostat can be connected to all appliances. To do this, connect the thermostat to the serial port using the associated connector. When an external thermostat is connected to the boiler the display shows T ON. Otherwise the display shows

T OFF.

No temperature measurement is shown on the display as there if no local room sensor. The boiler only waits for the external thermostat to close or open the contact to switch on, switch off or alter its power. If there is no external room thermostat the power will be fully dosed on the temperature of the water in the boiler. In the same way, it is possible to connect an external water sensor (to insert in a puffer or accumulation tank, for example) or a domotic control unit.

5.3.2. ECO-STOP mode

This function can be considered an "advanced automatic" mode that prompts the appliance to switch off when the temperature is reached rather than simply reducing the minimum power (ECO). We recommend that you DO NOT use the ECO-STOP function in rooms with minimal insulation or if cooling

in the installation room is very sudden. If used in these conditions the appliance will be forced to switch on and off frequently.

7. Fault signalling

7.1. Alarm signal and exiting alarm conditions.

Starting from the alarm intervention the appliance enters an automatic cooling phase which is very similar to the "shut down mode". This ensures that the system is cooled correctly and cleaned automatically. If an operating fault is detected the stove signals this with an acoustic signal and informs the user of the type of fault, displaying this on the control panel. If you wish to stop the acoustic signal to continue the cooling phase, simply press the ON/OFF Some alarms can be cancelled by simply pressing the key. Examples of these alarms include "start-up failed" or "flame extinguished". Other alarms require the intervention of a specialised technician. If an alarm intervenes, to restore normal operation of the stove hold down the ON/OFF key for a few seconds. After a brief period during which the appliance checks whether the cause that triggered the alarm has subsided, the appliance exits alarm mode and can be restarted.

The types of alarm and types of alarm signal that relate to the control panels of the various RED appliances are shown below

8.1. LED -2 / NO ACC / A01= Start-up failed

The FAILED START-UP alarm of the appliance is signaled if the smoke temperature sensor does not reach 50 °C within the 15 minutes set for the start-up. This fault may arise for the following reasons:

 Infiltration of air from the seals on the door and cleaning compartments.  Fuel loading faults.  If start-up begins with the auger empty.  Malfunction of the pellet igniter.  Incorrect position or dirt in the brazier.

CAUTION!! The stove will only switch on if all of the seals ensure perfect sealing of the combustion chamber.

 Check that the openings for non-scheduled cleaning are securely closed and show no infiltration.  Check the condition of the seal on the smoke fan inspection opening.  Check that the door seal is airtight using a sheet of paper.

Position the sheet of paper between the fire door and the structure, close the door and try to withdraw the sheet of paper. If the sheet of paper is easily extracted the seal must be checked or replaced. If the seal is compliant with the specifications, perform this test along the entire perimeter of the door seal.

 Check the condition of the door seal on the ask drawer using the same method described above.  Check that the eccentric bushing of the door handle is securely locked.  Check that the brazier is positioned correctly and that the holes in the brazier are all clean.  Check that the tank is full of pellets.

SOLUTION 1

If electronic and mechanical components are all working absolutely correctly and the combustion chamber is fully watertight, look for the fault in the assembly formed by brazier, igniter duct and air inlet duct.

The most likely causes are a result of excessive distance between igniter duct and brazier hole. In this case, it may be used to:

 Widen the hole of the brazier to Ø 12 mm.  Check that the holes of the igniter duct are free and allow easy introduction of air to be heated and

start-up.

 Check that the air inlet pipe is not ducted using a pipe that is too long or winding.

SOLUTION 2

In this situation, only the fume sensor can be responsible for the problem. The fume sensor is not communicating the correct temperature increase to the motherboard, even if the flame is lit. Therefore, the NO FIRE” alarm is triggered at the end of the start-up process (15 minutes).

In this case, check whether:

 the fume sensor correctly positioned and consequently not in contact with hot fumes  the fume sensor is insulated by too much silicon contained in the well  the fume sensor on the motherboard is wired incorrectly; the sensor always indicates minimum value

(30 °C) when the polarities are reversed.

N.B. The fume sensor in this case is not damaged; the alarm on the panel would be different if it were. LED +2 / ALAR SOND FUMI / A04 = Smoke sensor alarm

8.2. LED -1 / ALAR NO FIRE / A02 = Abnormal fire extinguishing

This type of alarm is detected when the smoke sensor drops below 50 °C. This fault may arise for the following reasons:

 Poor intake of fuel into the brazier due to an incorrect recipe setting and therefore extinguishing of the

flame due to a lack of pellets to burn.

 Excessive fuel intake in the brazier due to an incorrect recipe setting and therefore suffocation of the flame.  Empty pellet tank.  Smoke sensor that does not correctly detect the temperature of the smoke.

The stove is operating correctly and combustion is regular only if all of the seals guarantee that the combustion chamber is perfectly sealed.

 Check that the openings for non-scheduled cleaning are securely closed and show no infiltration.  Check the condition of the seal on the smoke fan inspection opening.  Check that the door seal is airtight using a sheet of paper.

Position the sheet of paper between the fire door and the structure, close the door and try to withdraw the sheet of paper. If the sheet of paper is easily extracted the seal must be checked or replaced. If the seal is compliant with the specifications, perform this test along the entire perimeter of the door seal.

 Check the condition of the door seal on the ash drawer using the same method described above.  Check that the eccentric bushing of the door handle is securely locked.  Check that the brazier is positioned correctly and that the holes in the brazier are all clean.  Check that the tank is full of pellets.

SOLUTION 1

In this situation the problem is an incorrect recipe selection, causing:

 Excessive fuel load.  Poor combustion quality that leaves waste and obstructs the holes of the brazier.

In this situation it may be useful to:

 Change to a certified fuel type (DIN +, etc.).  If the blockage and consequent extinguishing of the flame occur for a long period of time (7-8 hours) if

may be sufficient to decrease the intake of pellets by reducing the recipe (e.g.: from LED 0 a LED -1) to slightly reduce the amount of pellets entering the combustion chamber. If available, you may also think of increasing the recipe by two points to resolve blockages that are a little more consistent.

 If the blockage and consequent flame extinguishing occur for a short period (2-3 hours) the recipe must

be modified substantially to reduce the pellet intake.

If the problems are not risolved the solutions are:

 Check the airtightness of the combustion chamber and the entire area of the smoke passage where

there is a vacuum.

 Modify the installation.

SOLUTION 2

In this situation the problem is an incorrect recipe selection, causing:

 Poor fuel load.  Incorrect interpretation of the installation type (HORIZONTAL or VERTICAL).  Poor combustion quality that leaves waste and obstructs the holes of the brazier.

In this situation it may be useful to:

 Change to a certified fuel type (DIN +, etc.).  If the flame always remains low, even at maximum power levels, this means that you must reduce the

recipe (e.g.: from M7 to M6) to increase the quality of pellets entering the combustion chamber.

8.3. LED 0 / ALAR SIC FAIL / A03= Pellet tank safety thermostat

This type of alarm occurs when the bulb thermostat or contact thermostat positioned on the tank exceed the safety temperature set at 110 °C. This alarm can also intervene if the temperature of the water in the boiler exceeds the temperature by 90 °C. In HYDRO stoves there is a second bulb thermostat for safety that prevents the water in the boiler from boiling. This safety device can intervene if:

FOR ALL APPLIANCES

1. The appliance has been operating for too long at maximum power with the hot air ventilation at low levels.

2. The quality of pellets is poor and causes the structure to overheat.

3. The recipe or combustion calibration is incorrect and the flame is always very high as it is overloaded with fuel.

4. Blocking or breakage of the hot air fan that also cools the structure.

5. Damage to the bulb/ contact thermostat.

8.6. LED +2 / ALAR HOT TEMP / ALAR SOND FUMI / A04

Overheating of the smoke above a certain safety temperature that can be between 250 °C and 280 °C, depending on the type of product. This fault can be caused by:

 Uncertified pellets that contain chemical substances (glue, thickening agents, etc.) that increase

temperatures.

 High quantity of dirt and ash inside the smoke passage chambers. The ash insulates the heat exchange

walls and does not allow heat to dissipate. CLEAN THE APPLIANCE FULLY.

 Incorrect recipe and constant fuel overloading that causes temperatures to rise.  SMOKE SENSOR broken. This fault can be caused simply by natural electrical phenomena. Therefore, it

is useful to replace the component, given the importance of this device.

 Wiring fault. If the alarm is not caused by breakage of the component, it may be due to incorrect wiring.

Therefore, check that the smoke sensor is securely connected to the motherboard.

CAUTION!!

The two smoke sensor cables (BLUE and RED) have (+ and –) polarity. Therefore, take care to ensure

that the cables are inserted correctly (see the wiring diagram of the stove that you are operating on). With regard to ACTIVE SYSTEM appliances, the smoke sensor is fitted with a special connector to insert in the motherboard. This eliminates the possibility of errors. With regard to PELLET BOX stoves, the smoke sensor is wired directly to the motherboard. There may, potentially, be a wiring defect.

To test the correct operation of the smoke sensor, observe the temperature on the appliance display.

8.7. A10

This alarm signals that THE PELLET IGNITER IS NOT WORKING. The motherboard detects that the component is not absorbing the voltage and signals this fault. Replace the igniter after a brief test with an electrical tester.

8.8. A11

This alarm signals that THE GEARED MOTOR IS NOT WORKING. The motherboard detects that the component is not absorbing the voltage and signals this fault. Replace the geared motor after a brief test with an electrical tester.

8.9. A13

Alarm A13 identifies a generic communication problem between the motherboard and the other appliance components.

The motherboard is able to perform diagnostics on components and on itself when communication between the various elements stops (geared motor, sensors, fans, etc). If the fault involves parts such as the geared motor or pellet igniter the motherboard communicates a specific alarm (A10, A11, etc). In other situations the fault is a little more complicated and generic and alarm A13 is used. The clearest example of the complex nature of the fault can be identified with the electromagnetic interference in the wiring.

A13 DOES NOT MEAN THAT THE MOTHERBOARD IS FAULTY AND DEFINITELY NEEDS REPLACING but you must check for possible communication problems. Sometimes replacing the

motherboard has a positive effect. This is only because the connection problem is solved by disconnecting

and reconnecting the flat cables. This alarm can arise for the following reasons:

 The mother board is faulty.  The motherboard is not able to communicate sufficiently with other components due to electromagnetic

interference that is created between the cables that high voltage passes through (220 Volt cables that supply the fans, the pellet igniter, the geared motor) and the cables that low voltage passes through (12 or 5 Volt: flat cables, smoke sensor cable, encoder, control/ receiver panel). In this situation the electrical system of the appliance must be rewired, taking great care not to band together the two types of cable (particularly the encoder and receiver cables).

 Overheating of a component that operates in a faulty manner and therefore does not respond sufficiently to

the motherboard. The components that can, potentially, cause this type of fault are the smoke blower fan and the pressure switch. These situations can occur easily as the appliance, when cold, restarts without signalling further alarms,

SERVICE MANUAL

page 42

Rev. 02

08/11 – M.C.

Service Manual – 8901118900 – EN

given that the operating temperatures have returned to normal. The nature of the overheating can be due to:

o The smoke blower fan overheating because it is under excessive strain from faulty combustion.

The cause of alarm A13 is therefore the smoke blower fan, even if this component is not directly responsible for the fault. Check the combustion or, for safety, significantly decrease the amount of pellets entering the combustion chamber (-20% or -30%).

o The pressure switch can also cause alarms when it clicks repeatedly and is rapidly blasted by

external wind. Repeated and sudden electrical signals transmitted to the motherboard communicate an external fault. Therefore, alarm A13 is signalled. In this case the cause is external but it is ESSENTIAL TO MODIFY THE INSTALLATION to protect the pressure switch and resolve the fault.

9.6. Why perform scheduled maintenance?

Appropriate scheduled cleaning of the appliance allows better performance and, above all, better operation. The ash that thickens inside the exchange chambers act as a thermal insulator and diminish the product's ability to heat. This is because part of the heat cannot be absorbed by the structure and exits from the flue pipe or remains trapped in the structure itself, which is at excessive operating temperatures. Failure the clean the appliance also frequently causes combustion problems, blockage of fuel in the brazier and great difficulties in calibrating the recipe. The glass and/ or combustion chamber will frequently be dirty or blackened and ash deposits will increase exponentially.
