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 21 and 22 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.

HOT
Water temperature over 125 ° F 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.

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.
