Operating the water heater.
A. Do turn off power to water heater if
it has been subjected to overheating,
fire, flood or physical damage.
B. Do Not turn on water heater unless
it is filled with water.
C. Do Not turn on water heater if cold
water supply shut-off valve is closed.
D. Do Not store or use gasoline or other
flammable vapors and liquids, such as
adhesives or paint thinner, in the vicinity
of this or any other appliance. If such
flammables must be used, open doors
and windows for ventilation.
NOTE: Flammable vapors may be drawn
by air currents from surrounding areas to
the water heater.
E. 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.
WARNING:
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.

Installation Instructions
The water heater is equipped with two
temperature-limiting controls (TCOs) that
are located above the heating element in
contact with the tank surface. If for any
reason the water temperature becomes
excessively high, the temperature-limiting
control (TCO) breaks the power circuit to
the heating element. Once the control
opens, it must be reset manually. Resetting
of the temperature limiting controls should
be done by a qualified service technician.
CAUTION:
The cause
of the high temperature condition must
be investigated by a qualified service
technician and corrective action must
be taken before placing the water heater
in service again.
To reset the temperature-limiting
control:
1. Turn off the power to the water
heater.
2. Remove the jacket access panel(s)
and insulation.
The thermostat protective cover
should not be removed.
3. Press the red RESET button.
4. Replace the insulation and jacket
access panel(s) before turning on
the power to the water heater.
Safety Controls
WARNING:
If the water heater has been
subjected to flood, fire, or physical
damage, turn off power and water
to the water heater.
Do not operate the water heater
again until it has been thoroughly
checked by qualified service
