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 or lower Combination
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 18 and 19 for more details).
The temperature of the water in the heater can be
regulated by setting the temperature knob on the
front of the Combination Gas Control (Thermostat).
To comply with safety regulations the Combination
Gas Control (Thermostat) was set at its lowest
setting before the water heater was shipped from the
factory.
The illustration below details the approximate water
temperature for each mark on the Combination Gas
Control (Thermostat).
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
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 recommended for reducing
point of use water temperature by mixing hot and cold water
in branch water lines. It is recommended that a mixing valve
complying with the Standard for Temperature Actuated
Mixing Valves for Hot Water Distribution Systems, ASSE
1017 be installed. See pages 18 & 19 for more details and
contact a licensed plumber or the local plumbing authority
for further information.
