IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
!
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 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
32 & 33 for more details and contact a licensed plumber
or the local plumbing authority for further information.

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.

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 32 and 33 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
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.
