weeks the following procedure should be carried out before using any electrical
appliances (automatic washing machines and dishwashers) which are
connected to the hot water supply.
The hydrogen, which is highly flammable, should be vented safely by opening a
hot tap and allowing the water to flow. There should be no smoking or naked
flame near the tap whilst it is turned on. Any hydrogen gas will be dissipated.
This is indicated by an unusual spurting of the water from the tap. Once the
water runs freely again, any hydrogen in the system will have been released.
WATER SUPPLIES
Your water heater is manufactured to suit the water conditions of most
stralian metropolitan supplies. However, there are some known water
plies which can have
pectancy. If you are unsure of your water quality, you
obtain information from your local water supply authority. The water heater
uld only be connected to a potable water supply.

as where this is likely to occur, the installer should instruct the householder
how to dissipate the gas safely.
