ABOUT YOUR WATER HEATER
MODEL TYPE
Congratulations for choosing a Rheem
®
water heater. The model you have
chosen is suitable for indoor installation only. The model is either a 300 series
Rheemglas
®
or 620 series Heavy Duty water heater.
HOW HOT SHOULD THE WATER BE?
The water heater features a user adjustable
thermostat, which allows you to personally
choose the most suitable temperature for
your hot water needs. Refer to
“Temperature Adjustment” on page 4.
To meet the requirements of the National
Plumbing Standard the temperature of the
stored water must not be below 60
°C.
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
bathroom and ensuite when this water heater is installed. This will keep the
water temperature below 50
°C at the bathroom and ensuite. The risk of scald
injury will be reduced and still allow hotter water to the kitchen and laundry.
TEMPERATURE ADJUSTMENT
The temperature adjusting dial is on the gas
valve, located at the lower front of the water
heater. A setting of ‘6’ for a Rheemglas
model and ‘3’ for a Heavy Duty model will
normally maintain the water temperature at
about 60
°C. Each number represents a
temperature difference of approximately
6
°C.
To increase the water temperature to 65
°C for a Rheemglas model or to 80°C
for a Heavy Duty model, turn the gas control knob anticlockwise to a setting of
‘7’. Refer to
“Hotter Water Increases the Risk of Scald Injury” on page 4.
