General Safety
WARNING
Improper installation, adjustment, alteration, service or mainte-
nance can cause death, serious bodily injury, or property dam-
age. Refer to this manual for assistance or consult the local elec-
tric utility for further information.
WARNING
At the time of manufacture this water heater was provided with
a combination temperature-pressure relief valve certified by a
nationally recognized testing laboratory that maintains periodic
inspection of production of listed equipment or materials, as
meeting the requirements for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, and the latest
edition of ANSI Z21.22 and the code requirements of ASME. If
replaced, the valve must meet the requirements of local codes,
but not less than a combination temperature and pressure relief
valve certified as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22 by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equipment
or materials.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 lbs./sq. in.) and a discharge capacity not less than
the water heater input rate as shown on the model rating plate.
(Electric heaters - watts divided by 1000 x 3415 equal BTU/Hr.
rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve complying with ANSI Z21.22
and ASME, may require a valve model different from the one
furnished with the water heater.
Compliance with such local requirements must be satisfied by
the installer or end user of the water heater with a locally pre-
scribed temperature-pressure relief valve installed in the desig-
nated opening in the water heater in place of the factory fur-
nished valve.
For safe operation of the water heater, the relief valve must not
be removed from it’s designated opening or plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designated for the relief
valve. Position the valve downward and provide tubing so that
any discharge will exit only within 6 inches above, or at any dis-
tance below the structural floor. Be certain that no contact is
made with any live electrical part. The discharge opening must
not be blocked or reduced in size under any circumstances.
Excessive length, over 30 feet, or use of more than four elbows
can cause restriction and reduce the discharge capacity of the
valve.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
Drain unless a 6" air gap is provided. To prevent bodily injury,
hazard to life, or property damage, the relief valve must be
allowed to discharge water in quantities should circumstances
demand. If the discharge pipe is not connected to a drain or
other suitable means, the water flow may cause property dam-
age.
The Discharge Pipe:
—Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
—Must not be plugged or blocked.
—Must be of material listed for hot water distribution.
—Must be installed so as to allow complete drainage of both the
temperature-pressure relief valve, and the discharge pipe.
—Must terminate at an adequate drain.
—Must not have any valve between the relief valve and tank.
WARNING
HAZARD OF ELECTRICAL SHOCK! Before removing any
access panels or servicing the water heater, make sure the
electrical supply to the water heater is turned “off”. Failure to
do this could result in death, serious bodily injury, or proper-
ty damage.
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature which will
satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact.
Some people are more likely to be permanently injured by
hot water than others. These include the elderly, children, the
infirm, or physically/mentally handicapped. If anyone using
hot water in your home fits into one of these groups or if
there is a local code or state law requiring a certain temper-
ature water at the hot water tap, then you must take special
precautions. In addition to using the lowest possible temper-
ature setting that satisfies your hot water needs, a means,
such as a mixing valve, should be used at the hot water taps
used by these people or at the water heater. Mixing valves are
available at plumbing supply or hardware stores. Follow man-
ufacturers instructions for installation of the valves, Before
changing the factory setting of the thermostat, read the
“Temperature Regulation” section in this manual.
WARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This
water heater is equipped for one type voltage only. Check the
rating plate near the bottom access panel for the correct volt-
age. DO NOT use this water heater with any voltage other
than the one shown on the model rating plate. Failure to use
the correct voltage can cause problems which can result in
death, serious bodily injury, or property damage. If you have
any questions or doubts consult your electric company.
WARNING
INSULATING JACKETS: When installing an external water
heater insulation jacket on an electric water heater:
a. DO NOT cover the temperature-pressure relief valve.
b. DO NOT put insulation over the access covers or any access
areas.
c. DO NOT cover or remove operating instructions, and safe-
ty related warning labels and materials affixed to the water
heater.
WARNING
Do not use this appliance if any part of it has been under
water. An electrical short or malfunction could occur. The
water heater should be replaced.
CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater should be accomplished in such a manner that if the
tank or any connections should leak, the flow of water will not
cause damage to the structure. For this reason, it is not advis-
able to install the water heater in an attic or upper floor. When
such locations cannot be avoided, a suitable drain pan should
be installed under the water heater. Drain pans are available
at your local hardware stores. Such a drain pan must be piped
to an adequate drain. Under no circumstances is the manu-
facturer to be held liable for any water damage in connection
with this water heater.
