Zip Econoboil Installation & Operating Instructions - 82790 - January 2004
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.
It is recommended that the heater be installed with a stop cock which allows it to
be isolated from the mains supply for servicing.
Water pressure requirements:
Minimum - 0.2 bar, maximum - 10 bar..
Warning:
If pressure is likely to exceed 10 bar, a pressure limiting valve must be
installed in the cold water supply line. Zip recommends a valve rated at 3.5 bar
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 more than 3 right angle bends, and discharges to a waste
water drain.
For concealed vent plumbing, connect plumbing to the vent outlet from the
heater rear using a capillary elbow protruding 45 mm from the wall.
Alternatively attach a tun dish to the wall as shown and plumb away to waste.
