Installation
18
To check the operating pressure of the
appliance it is recommended at least 2
large size burners are used. Ensure
appliance is secured to wall when
installation is completed.
N.G. The regulator supplied must be fitted
to the ½ BSP thread at the rear of the
appliance. An approved manual shut-off
valve must be installed. The N.G. regulator
must be checked and adjusted to 1.0kPa
after installation.
U.L.P.G. Can be connected to the inlet
fitting directly. The pressure must be
checked to ensure it is operating at
2.75kPa. A separate test point fitting must
be installed between the piping & the
appliance for the pressure to be checked to
ensure it is operating at 2.75kPa.
Connection to liquid gas
Use a pressure regulator and make the
connection on the gas cylinder following
the guidelines set out in the regulations in
force.
Make sure that the supply pressure
complies with the values indicated in the
paragraph ““Burner and nozzle
characteristics table””.
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.
