ABOUT YOUR WATER HEATER
TO TURN ON THE WATER HEATER
If the water heater has been drained, screw in the drain plugs at the cold water inlet and
hot water outlet of the water heater and open all of the hot water taps in the house (don't
forget the shower). Open the cold water isolation valve fully at the inlet to the water
heater. Air will be forced out of the hot taps. As water flows freely from each tap, close
it. Open the gas isolation valve fully at the inlet to the water heater, plug the water heater
power lead into the electrical outlet and switch on. Turn on the water heater at the controller
(if fitted). The water heater will then operate automatically when you open a hot tap.
GENERAL MAINTENANCE
The jacket of the water heater can be cleaned with a soft cloth and warm mild soapy water.
Under no circumstances should abrasive materials or powders be used. Ensure the water
heater flue terminal and air inlet are not obstructed in any way at any time.
The water heater should be serviced annually by Southcorp Water Heaters Australia or
their Accredited Service Agent. Only genuine replacement parts should be used with this
water heater.
SAFETY INSTRUCTIONS
Propane models are designed to operate on Propane
only. The use of Propane/Butane mixture such as
automotive LPG fuel is unsafe and can cause damage
to the water heater.
Do not store or use chemicals or flammable
materials near the water heater.
Do not spray aerosols near the water heater.
Do not place anything on top of or against the
water heater, or in contact with the flue terminal.
The flue gases and the flue terminal on the water
heater are hot when the water heater is operating.
Keep clear of this area to avoid burns.
ELECTRICAL POWER
The water heater uses 240 volt AC electrical power for operation of the control systems and
the combustion fan. The power lead from the water heater must be plugged into a
weatherproof electrical outlet. Take care not to touch the power plug with wet hands.
