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
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.
D A N G E R
!
Water temperature over 125°
can cause severe burns
instantly or death from scalds.
Children, disabled and elderly are
at highest risk of being scalded.
See instruction manual before
setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.
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.

The chart shown above may be used as a guide in
determining the proper water temperature for your
home.
HOT
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F 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
BURN
thermometer. (See page 24 and 25 for more details.)
The temperature of the water in the heater can be
regulated by rotating the dial on the front of the
gas control (thermostat). To comply with safety
F (52°C)
regulations the gas control (thermostat) was set
at "HOT" position before the water heater was
shipped from the factory. The "HOT" dial position
corresponds to a water temperature of approximately
120°F. DANGER: Hotter water increases the
potential for Hot Water SCALDS. The illustration
below details the approximate water temperature
for each mark on the Gas Control (Thermostat)
Temperature Dial.
