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 heater’s 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 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.

temperature for your home.
