Step 3 – Connecting
a) Plumbing
For exposed plumbing connection, connect the cold water inlet pipe from the base of the heater directly
to the 15 mm or half-inch compression fittings with the nuts and olives provided.
For concealed plumbing connections, connect the cold water pipe through the rear of the chassis using
a 15 mm or half-inch capillary elbow.
Cold water pipes must be flushed before connection to the inlet. Any clogging due to sediment or fines
will adversely affect the operation of the heater.
The heater must be installed with an isolating valve which allows it to be isolated from the mains
supply for servicing.
Water pressure requirements:
Minimum - 70 kpa, maximum - 700 kpa.
Warning: If pressure is likely to exceed 700 kpa, a pressure limiting valve must be installed in the cold
water supply line. Zip recommends a valve rated at 350 kpa for this application.
b) Venting
A vent at the base of the heater must be plumbed to a safe visible location as, under certain
conditions, it may discharge cold or boiling water and/or steam.
For exposed vent plumbing, connect vent outlet from the base of heater to a
15 mm or half inch OD pipe which has a continuous fall, is no more than 3 metres long, has no
