The chart shown above may be used as a guide
in determining the proper water temperature for your
home.
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F
(49°C) or lower gas
control (thermostat) setting to prevent contact with “HOT”
water.
Maximum water temperatures occur just after the
burner has shut off. To find water temperature being
delivered, turn on a hot water faucet and place
a thermometer in the water stream and read the
thermometer. (See page 20 and 21 for more details.)
The temperature of the water in the heater can be
regulated by setting the temperature dial on the front
of the gas control (thermostat). To comply with
safety regulations the gas control (thermostat) was
set at its lowest setting
before the water heater
was shipped from the
factory.
The illustration at the left
details the approximate
water temperature
for each mark on
the Gas Control
(Thermostat)
Temperature Dial.
!
DANGER: Hotter water increases the potential for
Hot Water SCALDS.

DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the water
temperature setting of a water heater’s gas control. Water temperatures above 125°F
(52°C) can cause severe burns or death from scalding. Be sure to read and follow the
warnings outlined on the label pictured below. This label is also located on the water
heater.
Notice: Mixing valves are available for reducing point
of use water temperature by mixing hot and cold water
in branch water lines. Contact a licensed plumber or the
local plumbing authority for further information.
