General Safety
WARNING
Improper installation, adjustment, alteration, service or mainte­
nance can cause DEATH, SERIOUS BODILY INJURY OR PROP­
ERTY DAMAGE, Refer to this manual for assistance or consult
your local Sears Service Center for further information.
WARNING
At the time of manufacture this water 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 meet­
ing 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 Ibs./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 neater.
Compliance with such local requirements must be satisfied by the
installer or end user of the water heater with a locally prescribed
temperature-pressure relief valve installed in the designated open­
ing 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
info the fitting of the water heater designated for the relief valve.
Position the valve downward and provide tubing so that any dis­
charge will exit only within 6 inches above, or at any distance
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
15 feet, or use of more than two 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, haz­
ard 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 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 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
A fire can start if combustible materials such as clothing, cleaning
materials, or flammable liquids are placed against or next to the
water heater.
WARNING
WATER HEATERS EQUIPPED FOR ONE TYPE GAS ONLY: This

f
rating
USE
ONE SHOWN ON THE MODEL RATING PLATE. Failure to use the
correct gas can cause problems which can result in DEATH, SERI­
OUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any
questions or doubts consult your gas supplier or local utility.
WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES,
STORAGE, AND UTILITY AREAS, ETC): Flammable liquids (such as
S asoline, solvents, propane (LP) or butane, etc.), all of which emit
ammable vapors, may be improperly stored or used in such
areas. The gas watér heater pilot light or main burner can ignite
such vapors. The resulting flashback and fire can cause deatn or
serious Durns to anyone in the area, as well as property damage.
If installation in such areas is your only option, then the installa­
tion must be accomplished in a way that tne pilot flame and main
burner flame are elevated from the floor at least 18 inches. While
this may reduce the changes of flammable vapors from a floor spill
being ignited, gasoline and other flammable substances should
never be stored or used in the same room or area containing a gas
water heater or other open flame or spark producing appliance.
NOTE: Flammable vapors may be drawn by air currents from
other areas of the structure to tne appliance.
WARNING
HOTTER WATER CAN SCALD: Water heaters are intended to pro­
duce 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/men-
tally 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 requir­
ing a certain temperature water at the hot water tap, then you
must take special precautions. In addition to using the lowest pos­
sible 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 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.
WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]:
Propane (L.P.) gas is heavier than air. Should there be a leak in the
system, the gas will settle near the ground. Basements, crawl
spaces, skirted areas under mobile homes (even when ventilated),
closets and areas below ground level will serve as pockets for the
accumulation of this gas. Before attempting to li^ht or relight the
water heater's pilot or turning on a nearby electrical light switch,
be absolutely sure there is no accumulated gas in the area. Search
for odor of gas by sniffing at ground level in the vicinity of the
appliance. If odor is detected, follow steps indicated at "For Your
Safety" on the cover page of this manual then leave the premises.
WARNING ^ ,
Do not use this appliance if any part of it has been i^der water.
Immediately call a Sears Service Technician to inspect the appli­
ance and to replace the gas control or any part of the burner sys­
tem which has been under water.
