Relief Valve:
The Pressure & Temperature Relief (PTR)
Valve is supplied loose with the water
heater.
The PTR Valve rating is 1400 kPa.
The PTR Valve rating is also shown on the
compliance plate. The PTR Valve must
be installed directly into the RP½"(DN15)
socket marked "RELIEF VALVE" at the top
of the water heater on the right hand side.
Ensure that a sealing material is applied to
the PTR Valve to prevent water leaks.
The drain line from this valve must be
made of copper and run in accordance
with the requirements of AS/NZS 3500.4.
The PTR Valve and its drain outlet
pipe must not be sealed or blocked.
A separate drain line must be run for
the valve. It is not permitted to couple
drain lines from relief valves into a single
common drain line.
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.
INSULATION TO BE FITTED AFTER PTR VALVE IS INSTALLED

Plumbing Connections
Refer to AS/NZS 3500.4 for guidance on
these types of installations.
Fit the insulation supplied with the water
heater to the PTR Valve, after the PTR
is installed. Ensure the PTR lever is not
obstructed by the fitment of the insulation.
See below.
Caution:
Care must be taken when attaching
pipe saddles to the water heater. We
recommend the use of self drilling screws
no longer than 12 mm.
Hot Water Connection:
The hot water pipe is to be connected
into the RP¾"(DN20) socket marked
"OUTLET" at the top of the water heater
on the left hand side.
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.
