Installation
24
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.
Extraction of the combustion products
The combustion products may be extracted
by means of hoods connected to a natural
draught chimney whose efficiency is certain
or via forced extraction. An efficient
extraction system requires precision
planning by a specialist qualified in this
area and must comply with the positions
and distances indicated by the applicable
standards.
When the job is complete, the installer must
issue a certificate of conformity.
