WATER INLET AND OUTLET
Rheemglas 045 to 400 models have dual handed cold and hot water
connections. The water connections can be made to either side.
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.
An isolation valve and non-return
valve must be installed on the cold
water line to the water heater. An
acceptable arrangement is shown in
the diagram. Refer also to “Hot
Water Delivery” on page 23 and to
“Mains Water Supply” on page 23.
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.
This water heater has either a plastic dip tube or
fitting liner in the inlet and outlet fittings (see
diagram). These must be in place for the water
heater to function properly. Do not remove or
damage them by using heat nearby. They will be
pushed into the correct position as the fitting is
screwed in.
