Safety Precautions
Do turn off manual gas shut-off
valve if water heater has been
subjected to overheating, fire,
flood, physical damage or if the
gas supply fails to shut off.
Do Not turn on water heater unless it
is filled with water.
Do Not turn on water heater if cold
water supply shut-off valve
is closed.
Do Not allow combustible materials
such as newspaper, rags or mops to
accumulate near water heater.
Do Not store or use gasoline or other
flammable vapors and liquids, such
as adhesives or paint thinner, in
vicinity of this or any other
appliance. If such flammables must
be used, open doors and windows for
ventilation, and all gas burning
appliances in the vicinity should be
shut off including their pilot lights, to
avoid vapors lighting.
NOTICE: Flammable vapors may be drawn
by air currents from surrounding areas to
the water heater.
If there is any difficulty in
understanding or following the
Operating Instructions or the
Care and Cleaning section, it is
recommended that a qualified person
or serviceman perform the work.
Operating the water heater.
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a
long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such
gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound
such as air escaping 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
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 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.
