Operating the water heater. Installation Checklist
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.
Safety Controls
The water heater is equipped with a
combination thermostat and
temperature limiting control (ECO)
that is 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
(ECO) breaks the power circuit to the
heating element. Once the (ECO)
breaks, it must be replaced.
CAUTION: The cause of the high
temperature condition must be
investigated by qualified service
technician and corrective action must
be taken before placing the water
heater in service again.
To replace the temperature limiting
control:
Turn off the power to the water
heater.
Remove the jacket access
panel(s).
Remove the old thermostat and
replace it with a new one.
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
personnel.
