8.3 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 least 100
cm2, or 200 cm
2
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.
8.4 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.
