All plumbing work must be carried out by a qualified person and in accordance with the National Plumbing

Standard AS/NZS 3500.4 and local authority requirements.

All gas work must be carried out by a qualified person and in accordance with the Australian Gas

Installations Standard AS 5601 and local authority requirements.

WATER INLET AND OUTLET

All pipe work must be cleared of foreign matter before connection

and purged before attempting to operate the water heater. All

olive compression fittings must use brass or copper olives. Use

thread sealing tape or approved thread sealant on all fittings.

A full flow gate valve or ball valve must be installed on the cold

water line or solar preheat water line to the water heater. A non

return valve or stop tap must not be installed. An acceptable

arrangement is shown in the diagram. Refer also to “Hot Water

Delivery” on page 45 and to “Mains Water Supply” on page 44.

A disconnection union must always be provided at the cold water

inlet and hot water outlet on the water heater to allow for

disconnection of the water heater.

Insulation used on the cold and hot water lines must extend up to

the cold water inlet and hot water outlet of the water heater.

Notes:

It is essential all pipe connections be correctly aligned,

otherwise component connections within the water heater

may be strained and / or components themselves

misaligned. It is recommended also, wherever possible, pipe

connections be made at the water heater first and final pipe

runs be made in soft copper pipe to allow some adjustment

for misalignment.

Use the spanner flats on the water heater fittings and take

care to avoid twisting the water inlet and outlet pipes inside

the jacket.

later suffix letter after the model number on the rating label of

the water heater do not need to be installed with a solar

bypass valve:

 018 and 020 models - B

The maximum supply temperature to the water heater when used as an in-series gas booster for a solar
