Room ventilation
The room containing the appliance should
have a permanent air supply in accordance
with the standards in force. The room where
the appliance is installed must have enough
air flow needed for the regular combustion
of gas and the necessary air change in the
room itself. The hob shall be installed in
rooms with natural ventilation, as required
by Standards regulations AS/NZS5601.
Combustion gas discharge
Combustion gases may be discharged by
means of hoods connected to a flue with
reliable natural draught, or a fan extraction
system. An effective extraction system
requires careful design by an authorised
specialist, and must comply with the
regulation distances and positions. After
installation, the engineer must issue a
certificate of compliance.
