WATER INLET AND OUTLET
Stellar stainless steel electric models have dual handed cold water connections.
The cold water connection can be made to either side of the water heater. A
050 model also has dual handed hot water supply and temperature pressure
relief valve connections and these connections can be made to either side of the
water heater. Refer to “Left and Right Hand Side Water Connections” on
page 30.
The 080 to 315 models have a single hot outlet connection on top of the water
heater. Refer to “Heat Trap” on page 30.
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 all other threaded joints.
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 22.
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.
