2.3 Room ventilation
Caution – This hob may only be installed and operated in rooms
permanently ventilated in accordance with current regulations. For
proper operation of a gas appliance it is essential for the air necessary
for combustion of the gas to be able to flow naturally into the room. Air
must flow directly into the room through openings in its outside walls.
This (these) opening (s) must have a free passage cross-section of at
2
least 100 cm , or 200 cm2for 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.
2.4 Discharge of combustion products
Discharge of combustion products must be guaranteed by means of
hoods connected to a natural draught flue with certain efficiency, or by
means of forced aspiration.
An efficient aspiration system requires careful planning by a specialist
capable of installing it, respecting the positions and distances prescribed
by standards. After installation, the installer must issue a certificate of
conformity.
