compliance to AS 3498.

WATER HEATER OPERATION

The water heater operates automatically, heating water as it

passes through the water heater. When a hot tap is opened,

the gas burners ignite to provide immediate heating of the

water. The heat produced by the burner is transferred to the

water through the heat exchanger. The water is heated to a

constant temperature by the automatic adjustment of the gas

supply to the burner to suit the water flow rate. The gas burners

extinguish when the hot tap is closed.

Automatic safety controls are fitted to the water heater to

provide safe and efficient operation.
