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.
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
thermometer. (See page 28 and 29 for more details.)
The temperature of the water in the heater can be
regulated by pressing
the "COOLER" or "HOTTER"
arrow buttons 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 shows the approximate water
temperature for each LED Indicator on the Gas
Control (Thermostat) Temperature Display.

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 (thermostat). 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.
