cm2, or 200 cm2 for appliances not equipped with gas safety device.
These openings must be constructed so that they cannot be obstructed
indoors or outdoors, and should preferably be close to the floor on the side
opposite to the combustion gas discharge point. If it is not possible to
make the openings in the room where the cooker is installed, the
necessary air may be taken from an adjoining room, proveded it is not a
bedroom or a room with fire risk.

Combustion gases may be discharged by means of hoods connected to a
flue with reliable natural draught, or a fan extraction system. An effective

must comply with the regulation distances and positions. After installation,
the engineer must issue a certificate of compliance.
