WARNING
Improper installation, adjustment, alteration, service or mainte-
nance can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE. Refer to this manual for assistance or
consult the local electric utility for further assistance.
WARNING
At the time of manufacture this water heater was provid-
ed 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 rec-
ognized testing laboratory that maintains periodic inspec-
tion 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. p.s.i.) 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 3412 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 differ-
ent from the one furnished with the water heater.
Compliance with such local requirements must be satis-
fied by the installer or end user of the water heater with a
locally prescribed temperature-pressure relief valve
installed in the designated opening in the water heater in
place of the factory furnished 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 distance below the structural floor. Be cer-
tain 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 pre-
vent bodily injury, hazard to life, or property damage, the
relief valve must be allowed to discharge water in quanti-
ties should circumstances demand. If the discharge pipe is
not connected to a drain or other suitable means, the
water flow may cause property damage.
The Discharge Pipe:
—Must not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restriction.
—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 BODI-
LY INJURY, OR PROPERTY 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 perma-
nently injured by hot water than others. These include the
elderly, children, the infirm, or physically/mentally handi-
capped. 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 temperature water at the hot water tap,
then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfies your
hot water needs, some type of tempering device, 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 avail-
able at plumbing supply or hardware stores. Follow manu-
facturers 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 voltage. 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 prob-
lems which can result in DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. If you have any ques-
tions 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
safety 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 advisable to install the water heater in an
attic or upper floor. When such locations cannot be avoid-
ed, a suitable drain pan should be installed under the
water heater. Drain pans are available at your local hard-
ware store. Such a drain pan must be piped to an ade-
quate drain. Under no circumstances is the manufacturer
to be held liable for any water damage in connection with
this water heater.
