ALARM SIGNALLING
When a condition occurs other than the one expected for regular operation of the boiler, an alarm is triggered.
The reason for the alarm is given on the control panel. The sound signal is not enabled for alarms A01-A02 in order not to disturb the user
when there is an absence of pellets in the night tank.

Solution
A01

Make sure the spark plug warms up.
Thoroughly empty and clean the brazier before
restarting.

the alarm persists, contact the service centre.
Check whether the room fan is working correctly (if
there is one).

Service
Routine maintenance warning (does not seize) When this blinking message appears upon start-up, it
means it is time to carry out scheduled maintenance.
Call the assistance centre.
ALARM RESET
NEVER open the stove door whilst it is either in the initial start-up 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 combustion 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 technician
immediately.
