1. Lighting the Water Heater

Temperature Protection:

Water heaters can produce very hot

water. To reduce the risk of scald injury,

it is mandatory under the requirements

of AS/NZS 3500.4 that an approved

temperature control device be fitted to the

hot water supply to outlets used primarily

for personal hygiene. This valve should be

checked at regular intervals to ensure its

operation and settings remain correct.

Cold Water Connection:

The water heater is intended to be

permanently connected to the water

supply main.

An approved isolating valve, non-

return valve, line strainer (optional but

recommended) and union must be fitted

between the water supply main and the

RP¾"(DN20) socket marked "INLET" at

the bottom of the water heater on the left

hand side.

Note: a combined isolating valve/non-return valve/line strainer may be used.

The expansion control valve is only required where local regulations demand,

although it is recommended in areas where the water saturation index is greater

than 0.40.

All fittings must be approved by the

relevant Authority. Plastic pipes or fittings

shall not be used between the isolating

valve and the inlet.

See the diagram below for details.

Water Supply Pressure:

This water heater is designed for direct

connection to water supply pressures of

up to 1120 kPa.

Where the mains pressure can exceed

or fluctuate beyond the pressure shown

above, a pressure reducing valve must be

fitted in the cold water inlet supply.

Note for South Australia and Western

Australia:

It is a requirement in these locations that

an expansion control valve be fitted on the

cold water supply line between the non-

return valve and the water heater.
