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 18 and 19 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 below 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
!
HOT
Water temperature over 125° F (52°C)
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.

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 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.
IMPORTANT SAFETY INFORMATION.
