.
Do not turn the stove on again before checking the cause of the malfunction and CLEANING/ EMPTYING the crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES:
1) Signalling: H1) Veri! c./air " ow: (intervenes if the • ow sensor detects insuf• cient combustion ).
Problem: Turns off for lack of depression
Air • ow may be insuf• cient because the door is open, the door does not close properly (e.g. bad seal), there is an
air intake or smoke extraction problem, or the combustion chamber is clogged.
Actions: Check:
• door closure;
• combustion air intake duct (clean, paying attention to the • ow sensor components);
• clean the • ow sensor with dry air (like that used for PC keyboards);
• stove location: it must not be installed against a wall;
• combustion chamber position and cleanliness (clean regularly according to the type of pellet);
• smoke duct (clean);
• installation (if it does not comply with regulations or the smoke outlet has more than 2-3 bends);
If you suspect the sensor is malfunctioning, carry out cold tests. If the conditions are changed (for example by
opening the door) and the value does not change, there is a sensor problem.
N.B.: The no depression alarm may also occur during ignition, since the • ow sensor starts monitoring 90 seconds after
the ignition cycle begins.
2) Signalling: H2) Failure of fume expulsion motor (this trips if the smoke extraction speed sensor detects a fault)
Problem: Shutdown for smoke extraction speed fault detection
Actions: • Check smoke extractor function (devolution sensor connection) and board (DEALER).
• Check smoke channel for dirt
• Verify the electrical system and earthing system.
• Check eletronic circuit board (DEALER).
3) Signalling: SF (H3) Stop/Flame: (this trips if the thermocouple detects a smoke temperature lower than the value set,
which it interprets as the absence of • ames)
Problem: Turns off due to drop in smoke temperature
Flame may fail for any of the following reasons:
Actions: - lack of pellets
- too many pellets have suffocated the • ame, check pellet quality (DEALER)
• Check whether the maximum thermostat has caused the problem (rare circumstance since this would
correspond to over heated fumes (technical assistance centre)
• Check whether the pressure switch has cut off electricity to the gear motor because of a blocked • ue or other
problem.
4) Signalling: AF (H4) Failed ignition (intervenes if a • ame fails to appear within a maximum of 15 minutes, or if
ignition temperature is not reached).
Problem: Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
Flame does NOT appear
Actions: Check: - combustion chamber position and cleanliness;
- arrival of combustion air in the combustion chamber;
- if the heating element is working (DEALER);
- room temperature (if lower than 3°C use a • relighter) and damp.
- Try to light with a • relighter.
Flames appear, but AF appears on the display after Ar.
Actions: Check: (only by the Dealer)
- if the thermocouple is working (DEALER);
- start-up temperature setting in the parameters (DEALER).
5) Signalling: AL 05 black out stop (not a defect of the stove).
Problem: Turns off due to lack of electricity
Actions: • Check electricity connection and drops in voltage.
