DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with small
children, disabled, or
elderly persons may require
a 120°F or lower thermostat
setting to prevent contact
with HOT water.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by setting the
temperature dial of the adjustable surface
mounted thermostat(s) located behind the
jacket access panel(s).
Dual element heaters have two
thermostats.
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heaters
thermostat(s). The lower the temperature
setting, the greater the savings in energy
and operating costs.
To comply with safety regulations the
thermostat(s) are factory set at 120°F or
less where local codes require. This is the
recommended starting point.
Water temperatures above 125°F can
cause severe burns or death from scalding.
Be sure to read and follow the warnings
outlined in this manual and on the label on
the water heater. This label is located on
the water heater near the thermostat access
panel.
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 page 4 for more
details and contact a licensed plumber or
the local plumbing authority for further
information.
The chart below may be used as a guide in
determining the proper water temperature
for your home.

DANGER: Hotter water increases the potential for
Hot Water SCALDS.
