Inspections and maintenance
The fire goes out or the
boiler stops
automatically
1. The pellet tank is empty
2. Pellets are not input
3. Triggered pellet temperature safety probe
4. The door is not closed completely or the
gaskets are worn
5. Water tank temperature too high
6. Unsuitable pellets
7. Poor supply of pellets
8. Dirty combustion chamber
9. Clogged discharge
10. Faulty flue gas extraction motor
11. Faulty or defective pressure switch
1. Fill the pellet tank. If it is a first ignition, it may be the case that
combustion does not arrive in time and in the programmed
amount, since it must travel from the tank to the brazier
2. After repeated ignitions, there is no flame despite a regular
flow of pellets. The problem may be linked to the boiler’s com-
ponents or attributable to bad installation
3. Let the boiler cool down completely, reset the thermostat until
the block is removed and ignite the boiler again; if the problem
persists, contact technical service
4. Close the door or replace the gaskets with new original ones
5. Check correct operation of the water circulation pump and
replace the component, if necessary
6. Change the type of pellet with one recommended by the man-
ufacturer
7. Check the flow of pellets by technical service
8. Clean the combustion chamber by following the instructions
on the booklet
9. Clean the flue pipe
10. Check and replace the motor, if necessary.
11. Replace the pressure switch
The boiler operates for a
few minutes and then
switches off
1. Incomplete ignition phase
2. Temporary blackout
3. Clogged flue pipe
4. Faulty or defective temperature probes
5. Faulty glow plugs
1. Repeat the ignition phase
2. Refer to the instructions above
3. Clean the flue pipe
4. Check and replace the probes
5. Check and replace the glow plug, if necessary
The pellets accumulate in
the brazier, the glass of the
door is dirty and the flame
is weak
1. Insufficient combustion air
2. Damp or unsuitable pellets
3. Flue gas suction motor fault
4. Incorrect adjustment. Incorrect air and
pellet ratio
1. Make sure the air inlet in the room is present and
free. Make sure the combustion air filter on the Ø 5 cm
air inlet pipe is not obstructed. Clean the brazier and make
sure all holes are open. Clean the combustion chamber and
flue gas pipe
2. Change the type of pellet
3. Check and replace the motor, if necessary
4. Change the operating time of the auger from the controls
(technical parameters setting)
The flue gas suction motor
does not work
1. The boiler has no power supply
2. Faulty motor
3. The motherboard is faulty
4. The control panel is faulty
1. Check the mains voltage and protective fuse.
2. Check the motor and condenser and replace it, if necessary
3. Replace the P.C.B.
4. Replace the control panel
The air convection fan never
stops
1. The heat temperature control probe
is defective or faulty
2. Fan fault
1. Check probe operation and replace it, if necessary
2. Check motor operation and replace it, if necessary
Set to automatic, the
boiler always operates at
maximum power
1. Room thermostat set to maximum
2. Temperature detection probe fault
3. Control panel defective or faulty
1. Set the thermostat temperature again
2. Check and replace the probe, if necessary
3. Check and replace the panel, if necessary
The boilers starts “by itself”
1. Incorrect chrono-thermostat
programming
1. Check the chrono-thermostat settings
