4. SAFETY DEVICES
4.1 Breakdown of flue gas extractor
If the extractor stops, the electronic unit immediately prevents pellet feeding.
4.2 Breakdown of pellet load motor
If the motor stops, the stove continues to operate until the minimum cooling level is reached.
4.3 4 Failed ignition
If no flame develops during the ignition phase, the appliance automatically attempts a new ignition, this
time, though, without loading pellets.
If, after this attempt, the stove still has no flame, the stove display shows “FAILED IGNITION”. If you
attempt to light the stove again, the display shows “COOLING WAIT” which means “WAIT”. This function
reminds you that before lighting the stove, you must be sure that the brazier is free of dirt and
debris.
4.4 Temporary power cut
The appliance will re-light automatically after a brief power failure. When the power goes off, the stove may
emit a minute quantity of smoke inside the house for a period of 3 to 5 minutes.
THIS DOES NOT POSE ANY SAFETY RISK.
4.5 Electrical safety device
The stove is protected against violent changes in power by a master fuse on the rear of the stove (2A 250V
delayed).
4.6 Flue gas exhaust safety device
If the exhaust system fails, an electronic pressure switch stops the stove and an alarm is signalled.
4.7 Pellet temperature safety device
In case of overheating inside the pellet tank, this safety device blocks stove operation; resetting is manual
and must be performed by an authorised technician.
4.8 System pressure safety device
A mechanical pressure switch blocks any over-pressure in the system.
Resetting is manual and must be carried out by an authorised technician.
4.9 Boiling water safety device
In the event of a lack or minimum quantity of water, this device blocks the pellet feed. Reset is manual and
must be carried out by an authorised technician.
4.10 External devices
During stove installation, it is MANDATORY to adapt the system with a pressure gauge for viewing the water
pressure and an automatic discharge valve calibrated at 3 bar pressure.
4.11 Installation and safety devices
The installation and respective system connections, the start-up and final testing for correct operation must
be carried out with all due diligence by authorised professional technicians (Italian Law no. 46 of 5 March
1990), in full respect for the regulations in force, both national and regional, as well as for the instructions
given in this manual.
Extraflame S.p.A. declines any responsibility for damage to objects and/or persons caused by
the system.
