the water heater for clearance above to 
replace the anode.
A properly drained overflow tray must 
be used where property damage 
could occur from water spillage. (See 
AS/NZS3500.4.2 for further details). 
Warranty does not cover consequential 
damage due to heater leakage.

Water Supply Pressure

This water heater is designed for direct 
connection to water supply pressures of 
no greater than:

All Models – 1120kPa

Where the mains pressure can exceed 
or fluctuate beyond the pressure 
shown above a pressure limiting device 
(complying with AS1357) must be 
fitted in the cold water inlet supply. 
This device must be installed after 
the isolating valve and set below the 
pressure shown above. Note during 
periods of lower demand water pressure 
may increase.

Pressure & Temperature Relief 
Valve

The Pressure & Temperature Relief Valve 
is supplied loose with the water heater. 
The valve rating is:

All Models – 1400kPa

The PTR valve must be installed directly 
into the top socket marked “RELIEF 
VALVE”. The drain line from this valve 
must run in a continuously downward 

direction in a frost-free ambient position 
with the discharge end left open to 
atmosphere permanently. 
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 AS/NZS 3500.4 for guidance on 
these types of installations).
Open the PTR Valve for approximately 
10 seconds by lifting the lever on the 
valve to ensure water is relieved to waste 
through the relief drain pipe. Lower lever 
gently and check that it closes correctly.

Warning:

 We recommend that you 

open the PTR valve at least once every 
6 months. Failure to do this may result in 
problems with the water heater.
The PTR Valve must not be tampered 
with or removed. The water heater must 
not be operated unless this valve is 
fitted and in working order.
The PTR Valve should be checked for 
adequate performance or replaced at 
intervals not exceeding 5 years, or less 
in areas where local regulations apply. 

Important: 

The PTR Valve and its 

drain outlet pipe must not be sealed or 
blocked. It is normal for the PTR valve 
to leak a small amount of water during 
heating cycles.
