4.19. Exiting alarm condition
In case of an alarm intervening, to restore the normal operation of the
stove press the on/off key for a long time. After a short verification
phase if the cause that caused the alarm does not persist, the stove
leaves the alarm status and it may restart.
4.19.1. Shutdown of the stove
NEVER open the appliance door whilst the stove is
either in the initial startup or on its shut down cycle,
pellets will still be smoldering or therefore volatiles
may be present.
ATTENTION!
If during operation or initial ignition you encounter
smoke spillage in to the room from the appliance or
the flue then please switch off the appliance, ventilate
the room and contact the installation / service
engineer immediately.
The following things can cause stove shutdown:
 Overheating of the stove body (“A03”)
 Overheating of the smoke (“A04”)
 During the function of the stove, an uncontrolled air intake
occurred in the combustion chamber or an obstruction in the flue
pipe. (“A05”)
 Boiler overheating (“A18”)
WHAT TO DO:
When the stove is cold: if the message “A03” appears: The structure is
too hot because the product has been operating for too long at
maximum power, or it is poorly ventilated, or the air fans are faulty
When the stove is sufficiently cold, press button B of the control panel
to cancel the alarm A03. Once the alarm is cancelled it is possible to
relight the stove normally.
If the alarm “A04” appears the stove shutdown in automatic, leave it
to cool down for a few minutes and then re-light. Cancel the alarm and
re-light.
If the alarm “A05” appears: it is caused by prolonged opening of the
fire door or by substantial air infiltration (e.g. smoke fan inspection plug
missing). If not caused by these factors control and if necessary clean
the smoke duct and the flue pipe.
If the alarm “A18” appears: the stove shuts down due to the boiler
overheating. This can be caused by a lack of water circulating in the
system (pump blocked or faulty). Check that the circulation pump is
operating correctly and then cancel the alarm and restart the stove.
Only after the cause of the blockage has been permanently
eliminated can a fresh attempt to relight the stove be made.
