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 48
and to “Mains Water Supply” on page 47.
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.
•
PH-246CWHA series water heaters when installed as an in-series gas booster to a solar water
heater do not need to be installed with a solar transfer valve if the maximum solar preheat
water heater does not exceed 80°C.
•
The maximum supply temperature to the water heater when used as an in-series gas booster
for a solar water heater is 80°C.
