including the water heater. Care must be taken to avoid air locks. The cold

Plumbing & Plumbing Diagrams
Plumbing Connections
All pipe work must be cleared of foreign matter before connection and
purged before attempting to operate the water heater. Use thread sealing
tape or an approved thread sealant on all fittings (never use hemp).
All Aquamax storage cylinder water
fittings have a plastic liner fitted. These
liners must be in place for the water
heater to function properly. All liners are
correctly positioned during manufacture
and should not require handling during
installation, however if a liner is not
correctly inserted or aligned, it should be
gently pushed back into place before
connecting any plumbing fittings.
Warning: Plastic liners must be in place for the water heater to function
properly. Do not remove or damage liners.
Warning: Do not use heat near plastic liners. Heat can be transferred
by conduction which may damage liners.
Gas Inlet Connection
The gas inlet connection is made through the left hand side of the water
heater near the front access panel. Gas pipe work must be cleared of
foreign matter before connection and purged before attempting to light the
water heater. A gas isolation valve and disconnection union must be
installed to allow servicing and removal of the water heater.
Refer to AS 5601 or AS/NZS 5601.1 for the correct method of sizing the
gas supply pipe work to the water heater. Pipe size selection must take into
account the gas input of this water heater (refer to ‘Dimensions & Technical
Data’ on page 35) as well as the gas input of all other gas appliances in the
premises.
