1.3 Evacuation of exhaust fumes
The appliances must be placed in premises from which exhaust fumes can be evacuated in compliance with in

stallation standards. Our appliances are classified type A and cannot be connected to an exhaust fume pipe. The
exhaust fumes must be evacuated via extraction hoods or similar devices that are connected to an efficient flue or
else they must be evacuated directly to the outside at a rate that does not fall below the specified minimum rate.
In all cases, if the exhaust fumes are removed through forced evacuation, aspiration must be interrupted if the
aspiration value falls below the specified limit. The gas supply must be stored to the burners manually.
Installation operations, adaptations to other types of gas, commissioning and the elimination of system faults must
be carried out only by qualified personnel in accordance with current rules and standards. The gas systems, wiring
