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 an approved thread sealant
such as Teflon tape on threaded joints where required. Only use sufficient thread sealant to seal a joint. Refer
to the sealant manufacturer's guidelines for how much and where to use.
Warning: Sealant must not be allowed in the waterways of pipe work or fittings. Excess sealant may be
carried into the water heater where it will damage components and block the internal filter. This damage to
components or blockage of filter is not covered by the Rheem warranty and a service rectification fee will be
charged.
A full flow gate valve or ball valve must be installed on the cold water line. A non-return valve or stop tap
must not be installed.
Insulation used on the hot water lines must extend up to the hot water outlet of the water heater.
This water heater is intended to be permanently connected to the water mains and not connected by a hose-
set. A braided flexible hose or semi-flexible connector may be used for connection to the water heater, where
permitted by AS/NZS 3500.4.
WARNING – This appliance must only be installed in accordance with the acceptable plumbing configuration
specified in these instructions. Failure to do so may result in conditions where delivery temperature control is
inadequate. Refer to
Figure 3
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.
•
When tightening, use the back nuts and rubber washers supplied on the water heater fittings and take
care to avoid twisting the water inlet and outlet pipes inside the jacket. Connections should be finger tight
plus ¼ turn with a spanner.
