SAFETY DEVICES
FLUE EXHAUST BREAKAGE
If the exhaust stops, the electronic board blocks the functioning and sends the boiler in alarm.
PELLET FEED MOTOR BREAKAGE
If the motor reducer stops, the boiler continues to function until the minimum cooling level is reached.
NO IGNITION
If a fl ame is not developed during the ignition phase, the appliance automatically attempts ignition
again.
If no fl ame develops also in this case, the appliance will signal ignition failure alarm on the display.
TEMPORARY POWER CUT
If the lack of current is lower than 10 seconds, the boiler ignores everything and starts its normal functioning
in the state it was in. If the time interval is higher than 10 seconds, the machine will display the "BLACK-
OUT COOLING" alarm (see display table).
ELECTRIC SAFETY
The boiler is protected against strong current changes by a master fuse that is found in the rear part of the
boiler. (12.5 A 250V Delayed).
PELLET TEMPERATURE SAFETY DEVICE
If there is overheating inside the tank, this device blocks the pellet feed motor; restoration is manual and
must be performed by an authorised technician who will check the cause of the overheating.
PELLET PIPE THERMAL SAFETY
If the thermal sensor of the pellet pipe detects an increase in the temperature in the same pipe, it activates
a pipe cleaning cycle.
MECHANICAL SAFETY WITH FIRE-CUT ROTARY VALVE
At the base of the loading tank there is a fi re-cut rotary valve that prevents any fl ame propagation to the
pellet tank.
DOOR OPENING SAFETY DEVICE
The boiler doors must never be opened during functioning or when the boiler is still hot!! The opening of
the doors during functioning causes the boiler to block with the relative signal on the display.
