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 cm
2
, 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.
3.3
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.
