ALARM ALERTS
If an operating anomaly occurs, the product enters the shutdown phase due to an alarm and informs the user regarding the type of fault
by means of a 3 digit code that remains displayed on the emergency panel.
The alarm is indicated permanently by the relative three digit code, a flashing red LED that lights up on the emergency panel and an
intermittent buzzer for the first 10 minutes. Read the instructions in the following 2 paragraphs to cancel the alarm status and restore the
normal operating mode of the stove.
The following table describes the possible alarms indicated by the product, associated to the respective code that appears on the
emergency panel and helpful tips to resolve the problem.
MESSAGE ON THE
DISPLAY
TYPE OF PROBLEM SOLUTION
A01
The fire does not ignite. Check the level of pellets in the tank.
Check that the brazier rests correctly in its seat and has
no visible deposits or unburnt pellets.
Check whether the ignition plug becomes hot.
Empty and clean the brazier before relighting..
A02 The fire goes off abnormally. Due to the hopper being empty (no fuel).
A03
The pellet hopper temperature exceeds the
intended safety threshold.
The structure overheats due to reduced heat
dissipation.
The structure is too hot because the product has been
used for too long at the maximum power or due to poor
ventilation or because the air fans are faulty. When
the product is sufficiently cold, press button B on the
control panel to cancel the alarm. Once the alarm has
been cancelled, the appliance can be switched on.
A04
The temperature of the exhaust smoke has
exceeded the preset safety limits.
The appliance switches off automatically. Let the
product cool down for a few minutes and then switch
it on again. Check the smoke expulsion and the type of
pellets used.
A05 Clogged flue-wind-door open. Check the smoke duct and make sure the door is closed.
A06
The smoke extractor fails to guarantee sufficient
primary air, required for a correct combustion.
Insufficient draught or clogged brazier.
Verify whether the brazier is clogged and clean it, if
necessary.
Check and if necessary clean the smoke duct and air
inlet.
A08
Faulty smoke fan. Verify whether the smoke fan compartment is clean,
and particularly if it is blocked by dirt. If this does not
suffice, the smoke fan is faulty. Contact an authorised
service centre to have it replaced.
A09
The smoke probe is faulty and does not detect
the exhaust smoke temperature correctly.
Contact an authorised service centre to have the
component replaced.
