Relief Valve:
The Pressure & Temperature Relief (PTR) Valve,
along with a brass reducer, is supplied loose
with the water heater.
The PTR Valve rating is 1,000 kPa.
The PTR Valve rating is also shown on the
compliance plate. The PTR Valve must be
installed with the brass reducer directly into
a RP¾"(DN20) socket marked "RELIEF
VALVE". Ensure that a sealing material is
applied to the PTR Valve and the brass
reducer to prevent water leaks.
The unused socket (dual handed models)
marked "RELIEF VALVE" is to be plugged
with one of the brass plugs supplied loose
with the water heater. Ensure that a sealing
material is applied to the brass plug to
prevent water leaks.
The drain line from the PTR Valve must be
made of copper and run in accordance with
the requirements of AS/NZS 3500.4. It must
be installed in a continuously downward
direction in a frost free environment.
The PTR Valve and its drain line must not
be sealed or blocked. Generally a separate
drain line must be run for the valve although
it may be joined with the drain line from
the expansion control valve under certain
circumstances.
Care must be taken when attaching pipe
saddles to the water heater. Self-drilling screws
no longer than 12 mm are recommended.
It is normal for the valve to leak a small amount
of water during heating cycles.
The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as solar
panels or slow combustion stoves.

Plumbing Connections
Refer to AS/NZS 3500.4 for guidance on these
types of installations.
Hot Water Connection:
The hot water pipe is to be connected to a
RP¾"(DN20) socket with red surrounds at the
top of the water heater.
The unused socket (dual handed models only)
with red surrounds is to be plugged with one of
the brass plugs supplied loose with the water
heater. Ensure that a sealing material is applied
to the brass plug to prevent water leaks.
It is recommended that all hot water pipes are
insulated. Hot water pipes installed outdoors
should be insulated with UV stabilised insulation.
Plastic pipes or fittings shall not be used within
1 metre of the outlet although they may be used
downstream of a temperature control valve.
Refer to AS/NZS 3500.4 for further details.
Temperature Protection:
Water heaters can produce very hot water. To
reduce the risk of scald injury, it is mandatory
under the requirements of AS/NZS 3500.4 that
an approved temperature control device is fitted
to the hot water supply to outlets used primarily
for personal hygiene. This device should be
checked at regular intervals to ensure its
operation and settings remain correct.
Water Supply:
This water heater has been manufactured to
suit the water conditions of most Australian
& New Zealand metropolitan supplies.
Please note certain water supplies can have
a detrimental effect on the water heater and
its life expectancy. If you are unsure about
the water supply you can obtain information
from the local water supply authority.
