7.2. ALARM SIGNALLING
If there is an operating anomaly, the stove goes into alarm shutdown
mode and informs the user of the type of problem that has occurred via
a 3-figure code displayed on the rear emergency panel.
The alarm is permanently signalled by the corresponding 3-figure code,
by a flashing red light on the emergency panel, and, for the first ten
minutes of the alarm, by a periodic acoustic signal. To take the stove
out of alarm conditions and restore its normal operation, read the
instructions in the next two paragraphs.
The table below describes the possible alarms signalled by the stove,
associated to the respective code that appears on the emergency
panel, and useful suggestions to solve the problem.

TYPE OF PROBLEM SOLUTION
A01
Fire fails to ignite
Check the level of pellets in the hopper.
Check that the grate is properly inserted in its housing
and does not have any obvious unburnt incrustations;
Check whether the ignition plug heats.
A02
Fire extinguishes abnormally
It derives from a shutdown due to lack of fuel (hopper
empty).
A03
Pellet tank temperature exceeds foreseen
safety limit.
Overheating of the stove body
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 or OFF on the remote control to cancel the alarm
A03. Once the alarm is cancelled it is possible to relight
the stove normally.
A04
he smoke extractor is not able to provide the
primary air required for combustion.
Draught difficulties or clogging of grate.
Check whether the grate is clogged by incrustation and
clean as required.
Control and if necessary clean the smoke duct and the
air intake.
A08
Flue-gas exhaust fan broken
Check that the smoke fan compartment is clean and if it
is dirt that is blocking it.
If insufficient, the smoke fan is defective. Call an
authorized service centre to make the replacement.
