3 INSERT SAFETY
3.1 Safety distance from flammable materials
To prevent the risk of fire, unit positioning must respect a minimum distance from flammable materials, according to
that given in the technical table in the manual and on the data plate.
Pay attention to the type of cladding, which must not be in flammable material. In case of particularly fragile objects
such as furniture, curtains or sofas, increase the safety distance from the insert considerably.
3.2 Fume exhaust safety
In normal operation the combustion chamber is in a negative pressure, guaranteeing seal against possible smoke
leaks into the room. If a certain vacuum level is not reached or the fume exhaust outlet is blocked, the vacuum
switch detects the lack of a negative pressure inside the combustion chamber or the air flow meter detects a lack of
combustion air flow and, through the electronic controller, switches off the auger rotation motor, signaling the
anomaly with a message on the remote control 'AL 8 NO NEG PRESS' or 'AL 9 INSUF DRAFT'.
3.3 Combustion chamber overpressure safety
Any and/or sudden overpressures in the combustion fumes inside the chamber and fume exhaust ducts are
discharged by opening of the safety valves located on the heat exchanger. During normal operation these valves
are kept closed by their weight and the negative pressure in the combustion chamber, ensuring a seal against any
smoke escaping.
Periodically check closing, the integrity of the device and its operation.
3.4 Overheating - pellet hopper temperature safety thermostat
3.5 Safety against flare-back in the pellet chute
The solutions preventing flare-back are:
►
negative pressure in the combustion chamber see par. 3.2.
►
the siphon shape of the pellet chute.
►
the hopper temperature safety see par. 3.4.
3.6 Overcurrent protection device
The unit is protected against overcurrent by a 2A fuse fitted on the power supply of the controller's electronic board
mounted on the right side of the pellet hopper.
3.7 Power failure safety
In case of brief power failures, the unit relights automatically.
A temporary power failure does not limit insert safety and the hopper temperature does not reach high values (<
85°C), given the small amount of pellets burning in the brazier. This anomaly can result in some smoke briefly
escaping into the room, which does not involve any risk for safety.
Do not tamper with the safety devices.
3.8 Fume extractor fan failure
If the fume extractor fan stops for any reason, the electronic controller instantly stops the pellet feed, displaying the
message 'AL 4 FAN FAIL' on the remote control.
On the front and bottom of the hopper, and precisely on the pellet chute and on the
top part of the heating chamber, there are two temperature probes connected to
the respective safety thermostats that automatically shut off the pellet supply in
case of excessive heating. In this case the extractor and/or fans continue working,
allowing the stove to cool down rapidly. The fault is displayed on the control panel
with a message 'AL 7 THERMAL SAF'. In case of activation, proceed as follows:
►
Allow the stove to cool down for at least 45 minutes.
►
Reset the thermostat by pressing the button near the switch on the back of the
stove (figure opposite).
►
Restart the stove normally.
Pellet hopper thermostat activation temperature: > 85°C
Heating chamber thermostat activation temperature: > 95°C
