Safety Precautions
AWARNING J
Improper installation, adjustment, alteration, service or
maintenancecan cause DEATH, SERIOUS BODILY INJURY,J
OR PROPERTY DAMAGE. Refer to this manual for assis-
tance or consult your localSearsService Center for further
information.
AWARNING
At the time of manufacture thiswater heater was provided with
a combination temperature-pressures 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 Valvesand Automatic Gas
Shutoff Devicesfor Hot Water Supply Systems, andthe current
edition of ANSI Z21.22, CSA 4.4 and the code requirements of
ASME. If replaced, the valve must meet the requirements of
local codes, but not lessthan a combination temperature and
pressure relief valve certified as meeting the requirements for
Relief Valvesand Automatic Gas Shutoff Devicesfor Hot Water
Supply Systems, ANSI Z21.22, CSA 4.4 by a nationally recog-
nized 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 Ibs./sq. in.) and a discharge capacity not lessthan
the water heater input rate as shownon 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,
CSA 4.4 and ASME, may require a valve model different from
the one furnishedwith 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'sdesignatedopening or plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designated for the relief
valve. Positionthe valve downward and provide tubing so that
any dischargewill exit only within 6 inchesabove, or at any dis_
tance below the structural floor. Be certain that no contact is
made with any live electrical part. The dischargeopening must
not be blocked or reduced in size under any circumstances.
Excessivelength, 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 unlessa 6" air gap is provided. To prevent bod-
ily injury, hazard to life, or property damage, the relief valve
must be allowed to discharge water in quantities should cir-
cumstances 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 haveany reducing couplingsor other restrictions.
• Must not be pluggedor blocked.
• Must be of material listed for hot water distribution.
• Must be installed soas to allow complete drainage of both the
temperature-pressure relief valve,and the dischargepipe.
• Must terminate at an adequate drain.
• Must not haveany valve between the relief valve and tank.
AWARNING
HAZARD OF ELECTRICAL SHOCK! Before removing
any access panels or servicing the water heater, make I
sure the electrical supply to the water heater is turned
"OFF". Failure to do this could result in DEATH, SERI-
OUS BOD LY NJURY, OR PROPERTY DAMAGE.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a temper-
ature which will satisfy space heating, clothes washing, dish
washing, and other sanitizing needs can scald and perma-
nently injure you upon contact. Some people are more like-
ly to be permanently injured by hot water than others.
These include the elderly, children, the infirm, or physical-
ly/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 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, a means such as a mix-
ing valve, shall 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 manufacturers
instructions for installation of the valves. Before changing
the factory setting on the thermostat, read the
"Temperature Regulation" section in this manual.
AWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater is equipped for one type volt-
age 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 problems which can result in DEATH, SERIOUS
BODILY INJURY, OR PROPERTY DAMAGE. If you have
any questions or doubts consult your electric company.
AWARNING
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 remove operating instructions, and safety
related warning labels and materials affixed to the
water heater.
d. DO obtain new warning and instruction labels from
Sears for placement on the jacket directly over the
existing labels.
AWARNING
Do not use this appliance if any part of it hasbeen under I
water. An electrical short or malfunction could occur.
The water heater sboud be rap aced.
A CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must 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. 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 store. Such a drain pan must be
piped to an adequate drain.
