A non-return valve or stop tap must not be installed.
Disconnection unions must be fitted at both the heater’s cold inlet and hot outlet so that the
heater can be easily removed if required.
Insulation used on the cold and hot water lines must extend up to the cold water inlet and hot
water outlet of the water heater.
Use the spanner flats on the water heater fittings to avoid twisting the water inlet and outlet
pipes inside the heater case.
GAS CONNECTION
Ensure gas piping to the heater has been sized in accordance with Gas Installation Standard
AS/NZS 5601.

appliances on the property to operate at their maximum rated input.
A special fitting incorporating a gas pressure test point is included in the heater packaging.
Fit this to the gas inlet on the heater.
The gas supply may then be connected to the heater with a disconnection union at the heater
and an isolation valve. See Diagrams showing Typical Installations.
Note.
Ensure the heater the isolation valve is turned off before pressure testing the gas
supply pipework.
ELECTRICAL SUPPLY
All electrical work and permanent wiring must be carried out by a qualified person and in
accordance with the Wiring Rules AS/NZS 3000 and local authority requirements.

heater.
The GPO must be clear of the flue exhaust, gas supply pipe, water connections and draining
water.
The water heater will only operate on a true sine wave supply at 50 Hz. Devices generating a
square wave cannot be used to supply power to the water heater.
The Maximum power consumption of the heater with the burners on and the anti-frost system
active is 150Watts
