WARNING
At the time of manufacture thiswater 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 materlars, as
meeting the requirements for Relief Valves and Automatic Gas
ShutoffDevices 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 tess 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 Z2t.22 by a nationally recognized testing labo-
ratory that maintains periodic inspection of production o-flisted
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 beaters - watts divided by 1000 x 3415 equal
BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of a
temperature-pressure relief valve compiyin_ with ANSI Z21.22
and ASME, may require a valve model di_erent from the one
furnishedwith the water heater.
Compliance wilh 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-
nishedvalve.
For safe operation of the water heater, the relief valve must not
be removed from it's designatedopening or plugged.
The temperature-pressure relief valve must be i-nstalleddirectly
into tee 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 certain that no contact
is made with any llve electrical part. The discharge opening
must not be blocked or reducedin size under any circum-
stances.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 injur-y, hazard to llfe, or prO)pettydamage, therelief valve
must be allowed to discharge water in quantltles should cir-
cumstances demand. If the _]ischarge 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 r'estrictions°
--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 dlscbarge pipe.
--Must terminate at an adequate drain.
--Must not have any valve between the relief valve and tank.

bustible floors in an alcoveor closeL Refer to the label on the
water heater adjacent to the gascontrol vaive for ali clearances.
WARNING
HYDROGEN GAS:Hydrogengascan be produced in a hot water
systemthat has not beenused for a longperiod of time (generally
two weeks or more). Hydrogen gas is extremely flammable and
explosive_To prevent the possibilityof injury under these condi-
tions, we recommendthe hot water faucet be opened for several
minutes at the kitchensinkbeforeany electrical appliances which
are connectedto the hot water system are used(such as a dish-
washeror washingmachine). If hydrogengasispresent,there will
probablybe an unusual soundsimilar to air escapingthrough the

spilled out, could causestaining.
Facts to Consider About the
Location
You should carefully choose an indoor location for the
new water heater, because the placement is a very impor-
tant consideration for the safety of the occupants in the
building and for the most economical use of the appli-
ance This water heater is not for use in mobile homes or
outdoor installation.
Whether replacing an old water heater or putting the
water heater in a new location, the following critical
points must be observed,
I The location selected should be indoors as close as
practical to the gas vent or chimney to which the
water heater vent is going to be connected, and as
centralized with the water piping system as possible
The water heater, as all water heaters, will eventually
leak Do not install without adequate drainage provi-
sions where water flow will cause damage
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 Sears store. Such a drain pan
must be not greMer than lY_ inches deep, have a mini-
mum length and width of at least 2 inches greater than
the water heater dimensions and must be piped to an
adequate drain. The pan must not restrict combustion air
flow. Under no circumstances is the manufacturer or
Sears to be held liable for any water damage in connec-
tion with this water heater.
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 gasoline, solvents, propane (LP)
or butane, etc.) or other substances (such as adhesives,
etc.), all of which emit flammable vapors, may be improper-
ly stored or used in such areas. The gas water heater pilot
I!ght or main burner can ignite such vapors. The resulting
flashback and fire can causedeath or serious burns to any_
one in the area, as well as property damager
If installation in such are'as is your only option, then the
installation must be accomplished in a way teat the 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 sparkproducing appliance.
Also, the water heater must be located and/(}r protected so
it is not subject to physical damage bya moving vehicle.
NOTE: Flammable vapors may-be drawn by air currents
from other areas of the structure to the appliance°
WARNING
Propellants of aerosol sprays and volatile compounds,
(cleaners, chlorine based chemicals,refrigerants,etc_) in
addition to being highly flammable in many cases, wilt
also changeto corrosivehydrochloric acid when exposed
to the combustion products of the water heater_ The
resultscanbe hazardous,and alsocauseproductfailure.
2 The location selection must provide adequate dear-
ances for servicing and proper operation of the water
heater
WARNING
This water heater must not be installed directly on carpet-
ing. Carpeting must be protected by a metal or wood panel
beneath the appliance extending beyond the full width and
depth of the appliance by at least 3 inches (76.2mm) in
any direction, or if the appliance is installed in an alcove
or closet, the entire floor must be covered by the panel.
Failure to heed this warning may result in a fire hazard.
WARNING
Minimum clearances between the water heater and com-
bustible construction are i '_at the sides and rear, 4" at the
front, and 6" from the vent pipe. Clearance from the top of the
jackel is 18" on most models. Note that a lesser dimensmn may
be allowed on some models° Gas water heaters acceptable for
use on combustible floors in an alcove or closet° Refer to the
label on the water heater adjacent to the gas control valve for
all clearances.

WARNING
A gas water heater cannot operate properly without the
correct amount of air for combustion° Do not install in a
confined area such as a closet, unless you provide air as
shown in Figures 1-5. Never obstruct the flow of ventila-
tion air. If you have any doubts or questions at all, call
your_as company or Sears Service Center. Failure to
provide the proper amount of combustion air can result
m a fire or explosion and can cause DEATH, SERIOUS
BODILY INJURY, OR PROPERTY DAMAGE.
WARNING
If this water heater will he usedin beauty shops, barber
shops, cleaning establishments, or self-service laundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installedso that combus-
tion and ventilationair be takenfrom outside theseareas.

Combustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Unco_,fined Space is a space whose volume is not Jessthan 50
cubic feet per 1,000 Btu per hour of theaggregateinput rating
of all appliances installed in thatspace_Roomscommunicating
directly with the space in which the appliances are installed,
through openings not furnished with doors, are considered a
part of theunconfined space
In unconfined spacesin buildings, infiltration may be adequate
to provide air for combustion, ventilation and dilution of flue
gases,However, in buildings of tight construction (for example,
weather stripping, heavily insulated, cau]ked, vapor barrier,
etc.) additional air mayneedto be provided using the methods
described in Combustion Air and Ventilation for App lances

a.ALLAIRFROM INSIDE BUILDINGS:
(SeePageg Figure1, and Figure2 below)
The confined space shall be provided with two permanent
openingscommunicating directly with an additional room(s)
of sufficient volume so that the combined volume of all
spacesmeets the criteria for an unconfined space Thetotal
inputof all gas utilization equipment installed in the com-
bined space shall be considered in making this determina-
tion. Each opening shall have a minimum free area of one
squareinch per 1,000 8TU perhour of the total input rating
of a!l gas utilization equipment in the confined space, but
not lessthan I00 square inches. One opening shall com-
mence within 12 inches of the top and one commencing
within 12 inchesof the bottom of the enclosure
]. When directly communicating with the outdoors, each
opening shah have a minimum free area of t square inch
per 4,000 BTU per hour of total input rating of all equip-
ment in theenclosure tSeeFigure 3.)
2. When communicating with the outdoors through vertical
ducts, each opening shall have a minimum free areaof 1
square inch per 4,000 BTU per hour of total input rating
of all equipment in the enclosure (SeeFigure43

connect. Theminimum short side dimension of rectangular
air ducts shall not be lessthan 3 inches (SeeFigure5.)
5,.Louversand Grilles: In calculating free area, consideration
shall be given to the blocking effect of louvers, grilles or
screens protecting openings. Screens used shall not be
smaller than %inch mesh If thefree area through a design
of louver or grille is known, it should be used in calculat-
ingthe size opening required to provide the freeareaspec-
ified,. If the-design and free area is not known, it may be
assumedthat wood louvers will be 20-25 percentfree area
and meta] louvers and grilles will have 60-75 percent free
area.Louversand grilles shall be fixed in the open position
or interlocked with the equipment sothat they are opened
automatically during equipment operation.
6 Special Conditions Created by Mechanical Exhaustingor
Fireplaces:Operation of exhaust fans,ventilation systems,
clothes dryersor fireplaces may create conditions requiring
special attention to avoid unsatisfactory operation of
installed gasutilization equipment.
