All plumbing work must be carried out by a qualified person and in accordance

with the Plumbing Standard AS/NZS 3500.4 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.

An isolation valve and non-return

valve must be installed on the cold

water line to the water heater. An

acceptable arrangement is shown in

the diagram. Refer also to “Hot

Water Delivery” on page 20 and to

“Mains Water Supply” on page 19.

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.

This water heater has either a

plastic dip tube or fitting liner in the

inlet and outlet fittings (see

diagram). These must be in place

for the water heater to function

properly. Do not remove or damage

them by using heat nearby. They

will be pushed into the correct

position as the fitting is screwed in.
