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
This is because the fire goes out due to lack of fuel
(hopper empty) or by an excess of pellets in the grate
which suffocates the flame.
A03
Pellet hopper temperature exceeds required
safety limit.
Overheating of the stove body
The air fan may be damaged or stopped, and is not able
to cool the structure. wait until the structure is cool
before restarting the stove.
A04
The temperature of the smoke discharge has
exceeded pre-set safety limits
The stove will shut off automatically. Let the stove cool
off for a few minutes, then re-light it.
Check smoke release and position of the temperature
probe.
Check the type of pellet being used.
A05
The pressure switch has tripped due to
obstruction of the flue pipe caused by foreign
objects, soot/ashes or atmospheric agents
(wind, snow, etc.)
Check and clean the WHOLE flue system
Protect the outlet from the wind.
A06
The 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.
Check and clean flue system as necessary
A07
During operation of the stove, superfluous air
is getting into the combustion chamber
Caused by prolonged opening of the fire door or by
substantial air infiltration (ash drawer missing or smoke
fan inspection plug missing)
A08
The smoke extractor is not running.
Check that the smoke fan compartment is clean and if it
is dirt that is blocking it.
Smoke fan failure. Replacement
A09
The smoke probe is defective and does not
properly measure the temperature of the
discharge smoke
Contact an authorized service centre to replace the
component.
A10
The plug is defective
Contact an authorized service centre to replace the
component.
A11
The reduction motor for feeding pellets to the
grate has failed

A12
The remote control has been beyond the
reception range of the stove for more than
three hours, or its batteries are dead.
NOTE: only in this case the stove does not go
into alarm shutdown, but continues operating
in the mode that the remote control set via
the last sent command.
Move the remote control back to within range of the
stove, or change the batteries if they are dead.
As soon as the stove receives a new signal from the
stove, the alarm indications will disappear. A easy way
to force a transmission to the stove is to press button 4.
This changes operating mode from manual to automatic
and vice versa.
A13
Generic failure of electronic control unit
Contact an authorized service centre to replace the
component.
A14
Generic failure of sensor

signal will disappear automatically after a few seconds.
If instead the unit has gone into alarm status due to
lack of pellets, fill the hopper, cancel the alarm and
restart.
