Operating the water heater.
CAUTION: Hydrogen gas can be produced in a hot watersystem served by this water heater that has not been used for a
long period of time (generally two weeks ormore). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such
gas and to reduce risk of injury, it is recommended that the hot waterfaucet be opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot watersystem. If hydrogen is present, there will be an unusual sound
such as airescaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the
time it is open.
DANGER: There is a hot
waterscald potential if the
thermostat is set too high.
Households with small children,
disabled, orelderly persons
may require a 120°F. orlower
thermostat setting to prevent
contact with HOTwater.

Water Temperature Setting

The temperature of the water in the water
heater can be regulated by setting the
temperature dial on the front of the
thermostat.
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 was 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.
Mixing valves for reducing point of use
water temperature by mixing hot and cold
water in branch water lines are available.
Contact a licensed plumber or the local
plumbing authority for further information.
