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. 

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.
