GAS INLET

The pipe work must be cleared of foreign matter before connection and purged before attempting to
light the water heater. An isolation valve and disconnection union must be used to allow servicing and
removal of the water heater. Refer to AS 5601 for the correct pipe sizing.
Always isolate the water heater before pressure testing the gas supply system. Disconnect
the water heater after the isolating cock to prevent the risk of serious damage to the gas
train. Warranty does not cover damage of any nature resulting from failure to observe this
precaution. Refer to rating label for gas types and pressures.
The heater and its gas connection must be thoroughly leak tested before placing in operation. Use
soapy water and a manometer for leak test.
Do not use an open flame to check for gas leaks.
