Installation Procedures

Step 3 – Connecting
THE FOLLOWING PROCEDURE IS TO BE DONE BY AN AUTHORISED
INSTALLER ONLY.
a) Plumbing
For exposed plumbing connection, connect the cold water inlet pipe
from the base of the heater directly to the 1/2” or 12.7 mm compression
fittings.
For concealed plumbing connections, connect the cold water pipe
through the rear of the chassis using a 1/2” or 12.7 mm capillary elbow
(# 63 Swivel Elbows).
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 - 70 kPa, maximum - 500 kPa.
Warning:
If pressure is likely to exceed 500 kPa, a pressure
limiting valve must be installed in the cold water supply line. Birko
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 1/2” or 12.7 mm 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.
Tun Dish part numbers:
Wall Mounted Tun Dish- 99017 and Straight Tun Dish- 99018.
Exposed power and water are
connected through base.
Concealed power and water
are connected through rear.
