Safety Precautions
A WARNING
Improper installatton, adjustment, alteration, service or
maintenance
can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. Refer to this manual
for assistance or consult your local Sears Service Center
for further information.
A WARNING
At the time of manufacture diis v/ater 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 Valves :md Automatic Gas
Shutoff Devices for Hot Water Supply Systems, and the current
edition of ANSI Z2I.22 • CSA 4.4 æid the code requirements of
ASME. If replaced, the valve must meet the requirements of
local codes, but not less than a combination temperature <md
pressure relief valve certified as meeting the requirements for
Relief Valves and Automatic Gas Shutoff Dewces for Hot Water
Supply Systems, ANSI Z21.22 • CSA 4.4 by a nationally recog­
nized te^ng laboratory that maintains periodic inspection of
production of listed equipment or materials.
The valve must be mariced with a maximum set pressure not
to exceed the marked hydrostatic woriting pressure of the
water heater (ISO lbs./sq. in.) and a discharge edacity not
less than the water heater input rate as shown on the model
rating plate. (Electric heaters - watts divided by lOOO x 3412
equd BTU/Hr. rate.)
Your locid jurisdictional autiiority, while mandating tiie use of a
temperatijre-pressure relief valve complying wth ANSI Z21.22 •
CSA 4.4 and ASME, may require a vidve model different from
the one furnished witii tiie 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 instidied 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 temperabjre-pressure relief valve must be instidled directly
into the fitting of the water heater designated for tiie relief valve.
Position the valve downward iuid provide tubing so that any dis­
charge will exit only within 6 inches <d>ove, or at any distance
below the structural floor. Be certain that no contact is made
^h 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 die 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, lb prevent bodily injury, haz­
ard to life, or ^operty damage, the relief vdve murt be idlowed
to discharge water in quantities should circumstances demand. If
the discharge pipe is not connected to a drain or other suititie
means, the water flow may cause prqserty dam<^.
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 disdibution.
• Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the dis­
charge pipe.
• Must terminate at an adequate dr^n.
• Must not have æiy v^ve betmen the relief valve æid 1 ш 1 к.
A 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, SERI­
OUS BODILY INJURY, OR PROPERTY DAMAGE.
A WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem­
perature which will satisfy space heating, 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 tem­
perature water at the hot water tap, then you must take
special precautions. In addition to using the lowest possi­
ble temperature setting that satisfies your hot water
needs, a means such as a mixing 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 set­
ting on the thermostat, read the “Temperature
Regulation” section in this manual.
A 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
problems which can result in DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. If you have any ques­
tions or doubts consult your electric company.
A 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 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.
A 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.
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 avail­
able at your local Sears Store. Such a drain pan must be
piped to an adequate drain.
