the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
If the stove shuts down, you need to let the Switch-off procedure fi nish before you can restart the stove.
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:
AL 01 fume probe faulty or disconnected
Problem:
Shutdown due to faulty or disconnected fume probe
• Check the fume probe connection to the board: check the operation with a cold test (DEALER).
Actions:
AL 02 Room sensor fault (this is activated if the probe is faulty or disconnected)
2) Signalling:
Problem:
Shutdown due to detected temperature anomaly
• Check the connection of the probe to the circuit board (DEALER)
Actions:
• Check the operation of the sensor (DEALER)
AL07 Thermal safety (this occurs when the safety thermostat, located on the pellet slide, trips due to over-
3) Signalling:
temperature in the pellet tank)
Excessive loading of pellets
Problem:
Check operation of motor (DEALER)
Actions:
4) Signalling:
AL 08 depressurisation lacking (this occurs when there is not suffi cient draft in the cold air intake pipe)
Problem:
The screw feeder is stopped
• Check that the cold air pipe is not obstructed
Actions:
• Check the pressure switch
• Check that the silicone tube is not clogged
AL 09 Failure of fume expulsion motor (this trips if the smoke extraction speed sensor detects a fault)
5) Signalling:
Problem:
Shutdown for smoke extraction speed fault detection
• Check smoke extractor function (devolution sensor connection) and board (DEALER).
Actions:
• Check smoke channel for dirt • Verify the electrical system and earthing system.
• Check eletronic circuit board (DEALER).
AL 10 Failed ignition (intervenes if a fl ame fails to appear within a maximum of 20 minutes, or if ignition
6) Signalling:
temperature is not reached).
Problem:
Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
Flame does NOT appear
Check: - combustion chamber position and cleanliness;
Actions:
- arrival of combustion air in the combustion chamber;- if the heating element is working (DEALER);
- room temperature (if lower than 3°C use a fi relighter) and damp. - Try to light with a fi relighter.
Flames appear, but AF appears on the display after Ar.
Check: (only by the Dealer)
Actions:
- • fume probe operation (DEALER);
- start-up temperature setting in the parameters (DEALER).
