2.8
Ventilation of rooms
The hob may be installed only in rooms with permanent ventilation, as
required by standards regulations in force. The room in which the hob is
installed must have sufficient air flow to satisfy the requirements of
normal gas combustion and of necessary air exchange in the room. The
air intakes, protected by screens, must be appropriately sized
(regulations in force) and placed so as not to be blocked in any way.
The room where the oven is installed should be suitably ventilated to
avoid overheating or excess humidity produced by cooking, and in the
case of lengthy use a window should be opened or the speed of any
ventilators should be increased.
2.9
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.
