CONNECTIONS – ELECTRICAL
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 all local codes and regulatory authority requirements.
Warning: Temperature controllers must not be fitted to this water heater (874 series) if it is installed as an
in-series gas booster with a solar water heater system because water at a temperature much higher than the
controller setting can be delivered. If a solar water heater is installed to an existing water heater installation,
then all controllers must be disconnected and removed.
The water heater is supplied with a 1.8 metre lead and plug and requires a weatherproof 220 - 240 V a.c.
50 Hz general purpose outlet (GPO) to be located within 1.2 metres of the installation. The GPO must be clear
of the flue exhaust, draining water, gas supply pipe and water connections.
The power consumption of the water heater is:
