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
page 17 and to
on page 16.
A disconnection union must always be provided at the
cold water (solar preheat) 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 (solar preheat) 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.
This model in-series gas booster
does not
need to be installed with a solar transfer valve if the solar
water heater has an over temperature protection system.
