Electrical device faults
Electrical safety
Should a sudden electrical surge occur (lightning)
the heat stove is protected by a 2.5 A 250V fuse
located at the rear of the heat stove, next to the
power supply cable.
Extract the drawer that contains it and replace it.
ATTENTION!
do not try igniting the heat stove before
the required time, as it might lock down.
In the event of lock turn off the switch at
the rear of the heat stove for 1 minute,
turn it on again and wait 10 minutes
before igniting again.
ATTENTION!
the power outlet where the heat stove is
plugged in must be fitted with "earthing
connection according to regulations
in force". The Manufacturer disclaims
any liability for damage to property and
harm to people caused by installation
negligence.
Failed ignition
If no flame develops during the ignition stage or
the flue gas temperature does not reach an ade-
quate level in the time interval set for ignition, the
stove in set to extinction and the display reads
“Alar No Acc”.
Press the "On/Off" key to reset the alarm. Wait for
the cooling cycle to be complete, clean the burn
pot and proceed with a new ignition.
Extinction during working phase
This occurs when the stove unexpectedly goes
out during normal operation (for instance be-
cause pellets in the tank have run out or due to a
pellet filling gearmotor fault).
The stove continues operating until it processes
any pellets in the burn pot, after which the display
reads “Alar No Fire” and the stove enters extinc-
tion mode.
Press the "On/Off" -----button to reset the alarm.
Wait for the cooling cycle to be complete, clean
the burn pot and proceed with a new ignition.
These alarms remind you that before performing
ignition, one must ensure the burn pot is com-
pletely free, clean and correctly placed.
Power outage
Should there be a power outage for a period
longer than one minute, the heat stove might emit
a minimal amount of smoke in the house: this
does not pose any risk for safety.
When the power supply is restored, the heat stove
will display the words “Cool Fire”.
After completing the cooling cycle, the stove will
automatically restart and go into the work mode
prior to the power outage.
