Owner's Information
Gas Control Valve:
As well as acting as a thermostat, the
gas control valve is fitted with over
temperature energy cut-outs.
The gas control valve must not be
tampered with or bypassed.
Replacement of the gas control valve
must only be carried out by a licensed
tradesperson or the manufacturer.
The water heater must not be operated
unless the gas control valve is fitted and
in working order.
Temperature Protection:
Water heaters can produce very hot
water. To reduce the risk of scald
injury, it is mandatory that an approved
temperature control device be fitted to
the hot water supply to outlets used
primarily for personal hygiene. This
device should be checked at regular
intervals to ensure its operation and
settings remain correct.

Not Using Hot Water?
If you are not expecting to need hot
water for more than a few days, the
control knob on the gas control valve
thermostat can be set to the
position to conserve energy. Alternatively,
the water heater can be shut down.
If the water heater is not used for two
weeks or more, a quantity of hydrogen
(which is highly flammable) may
accumulate inside the water heater tank.
To dissipate this gas safely it is
recommended that a hot tap be turned
on for several minutes at a sink, basin
or bath, but not a dishwasher, clothes
washer or other appliance.
During this procedure there must be
no smoking, open flame or any other
electrical appliance operating nearby. If
hydrogen is discharged through the tap
it will probably make a sound similar to
that of air escaping.
Water Heater Appears to be
Leaking:
If the water heater is heating a large
quantity of cold water, condensation
may form inside the water heater and
drip down onto the burner.
This is NOT an indication that the water
heater is leaking, but is the result of an
efficient gas combustion process.
