2.8 Emergency
Suitable fire-prevention devices should be arranged for any eventuality.
In case of a fire, proceed as follows:
- Immediately disconnect the plug.
- Extinguish the fire using suitable fire-extinguishers.
- Call the fire department immediately.
- Do not use jets of waters to extinguish the fire.
3 STOVE SAFETY
3.1 Safety distance from flammable materials
To prevent the risk of fire, stove positioning must respect a minimum distance from flammable materials, according
to that given in the technical table of the manual and on the dataplate.
Pay attention to the type of floor: for delicate and flammable materials it is advisable to use plates in steel or
toughened glass as a support base (see section 2 - Transport and Installation). In case of particularly fragile objects
such as furniture, curtains or sofas, increase the stove distance considerably.
3.2 Fume exhaust safety
In normal operation the combustion chamber is in a negative pressure, guaranteeing seal against possible smoke
leaks in 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 air flow
and, through the electronic controller, switches off the auger rotation motor, signalling the anomaly with a message
on the control panel 'AL 8 NO NEG PRESS' or 'AL 9 INSUF DRAUGHT'.
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, guaranteeing a seal against
any smoke escaping.
Periodically check closing, the integrity of the device and its operation.
