11.2 Room ventilation and combustion extraction
The room containing the appliance should have a permanent air supply in
accordance with the standards in force. The room where the appliance is
installed must have enough air flow for the regular combustion of gas and for the
air exchange needed in the room itself. The air vents, protected by grills, must
be suitably dimensioned in compliance with current standards and positioned so
that no part of them is obstructed.
The appliance must be kept adequately ventilated in order to eliminate the heat
and humidity produced by cooking: in particular, after prolonged use, you are
recommended to open a window or to increase the speed of any fans.
Combustion products can be extracted by means of hoods connected to a
natural draught chimney whose efficiency is assured or via forced extraction. An
efficient extraction system requires precision planning by a specialist qualified in
this area and must comply with the positions and distances indicated by the
applicable standards. When the job is complete, the installer must issue a
certificate of conformity.
