Hydrogen Gas; Water Temperature; Warning About Hot Water; Scald Hazards - Rinnai HD28E Operation & Installation Manual

WARNINGS & IMPORTANT INFORMATION

Hydrogen Gas

If the hot water heater is not used for two weeks or more, a quantity of hydrogen gas, which is highly flammable,
may accumulate in the water heater. To dissipate this safely, it is recommended that a non electrically operated
hot tap be turned on for several minutes at a sink, or bath, but not a dishwasher or other appliance. During this
procedure there must be no smoking, open flame or any electrical appliance operating nearby. If hydrogen gas is
discharged through the tap, it will probably make a sound like air escaping.

Water Temperature

The outlet temperature setting of the gas continuous flow heater is factory pre-set to 75°C.

WARNING ABOUT HOT WATER

This appliance may deliver water at high temperature. Refer to the Plumbing Code of Australia
(PCA), local requirements and installation instructions to determine if additional delivery
temperature control is required.
WARNING

SCALD HAZARDS

DANGER BEWARE OF
SCALDING HAZARDS
Always......
Test the temperature of the water with your elbow before placing your child in the bath, also carefully feel
water before bathing or showering yourself.
Supervise children whenever they are in the bathroom.
Make sure that the hot water tap is turned off tightly.
Consider.....
Installing child proof tap covers or child resistant taps (both approaches will prevent a small hand being
able to turn on the tap).
Installing tempering valves or thermostatic mixing valves which reduce the hot water temperature delivered
to the taps. Your local plumbing authority may already require that these be fitted. Contact your installer
or local plumbing authority if in doubt.
Never....
Leave a toddler in the care of another child. They may not understand the need to have the water
temperature set at a safe level.
