ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem® Heavy Duty Gas water heater. The
model you have chosen is either a 265 litre or 275 litre indoor or outdoor quick
recovery water heater.
HOW HOT SHOULD THE WATER BE?
The water heater has a maximum
temperature setting of 82°C and a minimum
temperature setting of 60°C. Refer to
“Temperature Adjustment” on page 4.
For applications requiring sanitising
temperatures, the thermostat should be set
at 82°C. Note: For temperatures above
80°C, a circulator must be installed.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60°C.
If this water heater is installed as an in-series booster water heater as part of a
commercial solar water heating system, to maximise solar contribution it is
recommended the thermostat is set at 60°C, unless sanitising temperatures are
required.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY.
This water heater can deliver water at temperatures which can cause scalding.
Check the water temperature before use, such as when entering a shower or
filling a bath or basin, to ensure it is suitable for the application and will not
cause scald injury.
We recommend and it may also be required by regulations that an approved
temperature limiting device be fitted into the hot water pipe work to the bathing
and public areas when this water heater is installed. This will keep the water
temperature below the maximum permitted by AS/NZS 3500.4 to these areas.
The risk of scald injury will be reduced and still allow hotter water to the kitchen,
laundry and other areas requiring sanitising temperatures.
TEMPERATURE ADJUSTMENT
The water heater features an electronic adjustable thermostat. We recommend
only a licensed tradesperson make any temperature adjustments. We advise
the thermostat be adjusted to the lowest temperature setting that meets your
needs, especially if there are young children or elderly people in the premises.
Refer to “Hotter Water Increases the Risk of Scald Injury” on page 4.
