INSTALLING THE GAS COOKER
Gas connection
Read these points before connecting to the gas supply:
• The appliance is preset for natural gas use, if LPG is
to be used see Conversion to LPG section.
• Gas installation must be made in accordance with AS/
NZS5601.1, the local gas fitting regulations, municipal
codes and other statutory regulations.
• The gas connection point is a ½” BSP external thread
located at the rear of the appliance as shown.
• The regulator is to be fixed to the manifold inlet at the
rear of the appliance ensuring the washer supplied with
the regulator is fitted in between the manifold and the
regulator. Th consumer piping is then connected to the
inlet of the regulator, either:
1. directly, or
2. using a hose assembly and in accordance
with Clause 6.10.1.9 of AS 5601.1 (High level
connection) When fitted to the appliance tthe
regulator is oriented to allow the hose to hang
downward. All connections are sealed using
a tape or jointing compound suitable for gas
connections.
