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 18
and to “Mains Water Supply” on page 17.
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.
The maximum supply temperature to the water heater when used as an in-series gas booster for a solar
water heater should not exceed 80°C.
