A,WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ-
UIDS (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.), all ofwhichemit flammabk
vapors,may be improperly stored or used in such areas.
The gaswater heater pilot light or main burner can ignite
suchvapors. The resulting flashbackand fire can cause
death or serious burns to anyonein the area, as well as
property damage.
If installation in such areas isyour only option, then the
installationmust be accomplishedin away that the pilot
flame and main burner flame are elevated from the floor
at least 18 inches.While this may reduce the chancesof
flammable vaporsfrom a floor spillbeingignited, gasoline
and other flammable substancesshouldneverbe stored or
used in the same room or area containing a gaswater
heater or other openflame or sparkproducingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasofthe structure to the appliance.
AWARNING
If this water heater will be used in beauty shops,barber
shops,cleaning establishments, or self-servicelaundries
with dry cleaning equipment, it is imperative that the
water heater or water heaters be installedso that com.
hustion and ventilation air be taken from outside these
areas. Refer to the "Locating The New Water Heater"
section of this manual and also the latest edition of the
National FuelGas Code, ANSI Z223.1, also referred to as
NFPA 54for specifics providedconcerningair required.
_WARNING
A fire canstart if combustiblemater_l.s suchas clothing,I
cleaningmaterials,or flammable liqu,dsare placedagainst
or nextto the water heater.
A,WARNING
At the time of manufacture this water heater was pro-
vided with a combination temperature-pressures relief
valvecertified by a nationally recognized testing labora-
tory that maintains periodic inspection of production of
listed equipment or materials, as meeting the require-
ments 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 require-
ments of local codes, but not lessthan a combination
temperature and pressurerelief valve certified as meet-
ing the requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22 by a nationally recognized testing laborato-
ry that maintains periodic inspection of production of
listed equipment or materials.
The valvemust 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 dividedby 1000x 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 valvemodel
different from the one furnishedwith the water heater.
Compliance with suchlocal requirements must be satis-
fied bythe installer or end user of the water heater with
alocally prescribed temperature-prossure relief valve
installedin thedesignated openingin the water heater in
_lace ofthe factory furnishedvalve.
or safe operation of the water heater, the rehef valve
must not be removed from it's designated opening or
plugged.
The temperature-pressure relief valve must be installed
directly intothe fitting ofthe water heater designatedfor
the relief valve. Positionthe valvedownward and provide
tubingsothat any dischargewill exit onlywithin 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 30 feet, or useof more than four elbowscan
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 dischargedrain unlessa6" air gap isprovided.
To prevent bodily injury, hazard to life, or property dam.
age, the relief valve must be allowed to dischargewater
in quantities should circumstances demand. If the dis-
chargepipeis not connected to a drain or other suitable
means, the water flow may causeproperty damage.
The DischargePipe:
Must not be smaller in size than the outlet pipe sizeof
the valve, or have any reducing couplings or other
restrictions.
Must not be pluggedor 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
dischargepipe.
• Mustterminate at an adequatedrain.
•Must not haveany valve between the relief valve and
tank.

Safety Precautions
a,WARNING
A gaswater heater cannot operate properly without the
correct amount of air for combustion. Do not install in a
confined area such a closet, unless you provide air as
shownin the "Locating The New Water Heater" section.
Never obstruct the flow of ventilation air. If you haveany
doubts or questionsat all, call your gascompany.Failure
to providethe proper amount ofcombustionair canresult
in a fire or explosion and can cause DEATH, SERIOUS
BODILY INJURY,OR PROPERTYDAMAGE.
_E,WARNING
This water heater must not be installed directly on car-
peting.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 anydirection, or ifthe appliance isinstalled
in analcoveor closet, the entire floor must be coveredby
the panel. Failure to heed this warning may result in a
fire hazard.
_,WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfyclotheswashing,dishwashing,
and other sanitizing needs can scald and permanently
injure you upon contact. Some people are more likelyto
be permanently injured by hot water than others. These
includethe elderly,children,the infirm, or physically/men-
tally handicapped.If anyone usinghot water in your home
fits into one of these groupsor if there is a localcode or
state lawrequiring a certaintemperature water at the hot
water tap, then you musttake specialprecautions.In addi-
tion to usingthe lowestpossibletemperature settingthat
satisfiesyour hot water needs, ameans such asa mixing
valve,shouldbe usedat the hot water taps usedbythese
people or at the water heater. Mixing valvesare available
at plumbing supplyor hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changingthe factory setting on the thermostat, read the
"Temperature Regulation"sectionin this manual.
_,WARNING
Soot build-up indicates a problem that requires correc-
tion before further use. Turn "off" gas to water heater
and leave"off" until repairs are made, becausefailure to
correct the cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
_,WARNING
VENT DAMPERS - Any vent damper,whether it isoperat-
ed thermally or otherwise must be removed if its use
inhibitsproperdraftingofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters havingthermal efficiency in excessof 80% may
producea relatively low flue gastemperature. Suchtem-
peraturesmay not be highenoughto properly open ther-
mally operatedvent dampers. Thiswould causespillageof
flue gasesand maycausecarbonmonoxidepoisoning.
Vent dampersmust bear evidenceof certification ascom-
plying with the latest edition of American National
Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,
cover electrically and mechanically actuated vent
dampers). Before installationof any vent damper, consult
your localSearsService Center or the gasutility for fur-
ther information.
AWARNING

The water heater with draft hood installedmustbe prop- I
erly vented to a chimney which terminates outdoors. I
Never operate the water heater unlessit isvented to the I
outdoors and has adequate air supply to avoid risks of
improper operat on,expos on or asphyxat on.
AWARNING
Minimum clearancesbetween the water heater and com-
bustibleconstructionare I" at the sidesand rear, 4" at the
front,and6" fromtheventpipe.Clearancefromthe top ofthe
jacketis18".Referto the labelonthe waterheateradjacentto

I AWARNING I
Do not usethis appli_of it hasbeen underI
water. Immediately call a Sears Service Technician to I
inspectthe applianceand to replace the gascontrol or any I
part ofthe burner systemwhichhasbeen under water. I
•,CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin such a manner
that iftbe tank or any connectionsshouldleak, the flow of
water will not causedamage to the structure. When such
locations cannot be avoided,asuitable drain pan should
be installed under the water heater. Drain pansare avail-
able at your localSears store. Such a drain pan must be
not greater than 1I/2 inches deep, have a minimum
length and width of at least 2 inches greater than the
water heater dimensions and must be piped to an ade-
quete 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 thiswater heater.
AWARNING
HYDROGEN GAS:Hydrogengascanbe producedin a hot
water system that hasnot been used for a long period of
time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive.To prevent the possi-
bility of injuryunder these conditions,we recommend the
hot water faucet he opened for several minutes at the
kitchen sink before any electrical applianceswhich are
connected to the hot water system are used (such as a
dishwasheror washing machine). If hydrogengasis pre-
sent, there will probablybe an unusualsoundsimilar to air
escaping through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucetat the time it isopen.
AWARNING
INSULATING JACKETS: When installing an external
water heater insulationjacketon agaswater heater:
• DO NOT coverthe temperature-pressure relief vaive.
• DO NOT put insulationover any part of the top of the
gaswater heater.
•DO NOT put insulationover the gascontrol valveor gas
control valve/burner cover,or any accessareas to the
burner.
• DO NOT let insulationaroundthe gaswater heater to
get within 8 inches of the floor (air must get to the
burner).
• DO NOT cover or remove operating instructions, and
safetyrelated warninglabelsand mateHais affixedto the
water heater.
Failureto heedthis will result in the possibilityof a fire or

Installation Instructions (cont'd)
Facts to Consider About the
Location
You should carefully choose an indoor location for the new
water heater, because the placement is avery important consid-
eration for the safety of the occupants in the building and for
the most economical use of the appliance. 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.
•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 pip-
ing system as possible. The water heater, as all water heaters,
will eventually leak. Do not install without adequate drainage
provisions where water flow will cause damage.
CAUTION
WATER HEATERSEVENTUALLY LEAK:Installationof the
water heatermustbe accomplishedin suchamannerthat if
thet_nkor anyconnectionsshouldleak,the flowof waterwill
not causedamageto the structure. When suchIocatloescan-
not be avoided,a suitabledrainpanshouldbe installedunder

Facts to Consider About the
Location (cont'd) Combustion Air and Ventilation for Appliances
Located in Unconfined Spaces
Unconfined Space is aspace whose volume is not less than 50
cubic feet per 1,000 Btu per hour of the aggregate input rating
of all appliances installed in that space. Rooms communicating
directly with the space in which the appliances are installed,
through openings not furnished with doors, are considered a
part of the unconfined space
I Figure 2 1ROOM INSTALLATION
(ACCEPTABLE)
A room is any enclosure which is at least 16" times
greater than the total volume of all the gas fired appli-
ances within the enclosure.
In unconfined spaces in 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, caulked, vapor barrier, etc.),
additional air may need to be provided using the methods
described in Combustion Air and Ventilation for Appliances
Located in Confined Spaces, b.

Located in Confined Spaces
Confined Space is a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour of the aggregate input rating of all
appliances installed in that space.
a. ALL AIR FROM INSIDE BUILDINGS:
(SeeFiguFes1through6)
The confined space shall be provided with two permanent
openings communicating directly with an additional room(s)
of sufficient volume so that the combined volume of all
spaces meets the criteria for an unconfined space. The total
input of all gas utilization equipment installed in the com-
bined space shall be considered in making this determination.
Each opening shall have a minimum free area of one square
inch per 1,000 BTU per hour of the total input ratingof all
gas utilization equipment in the confined space, but not less
than 100 square inches. One opening shall commence within
12 inches of the top and one commencing within 12 inches
of the bottom of the enclosure.

Filling the Water Heater
.ACAUTION
Never usethiswater h_ completelyfilled with
water.To preventdamageto the tank,the tank mustbefilled
with water• Water must flow from the hot water faucet
before turnng ON gastothe waterheater.
To fill tee water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
• Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
•To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until aconstant flow is obtained. This will let air out of the
water heater and the piping.
Check all new water piping for leaks. Repairasneeded.

Where an exhaust fan is installed in the same room as the
water heater, air will be drawn into the room through the
chimney. Air supply openings must be large enough to admit
air exhausted by the fanant1that required'by all gasburning
appliances. A down-draft or back-draft willprevent proper
combustion, causing soot which may result in serious damage
to the water heater.
Where continuous or intermittentbackdraft is found to exist,
check chimney conditions, in some casesa blower type flue
gasexhauster must be employed between the appliance and
the stack to assureproper venting and correct combustion.
Combining vents as shown below is satisfactory, providing the
basic rules of good venting are observed. In either case the
vertical rise ab6ve drafthood (X) before any fittings should be
as great as possible. All venting connections should be made
in accordance with local codes and ordinances.
When vents are combined, area of the combined vent
should be equal to area of the largest single vent, plus 50%
of area of all others joining it.
EXAMPLE: To combine two 6" vents with an 8" vent, the
area of a combined vent should be one half
area of two 6" vents (14+14) plus area of 8"
vent (50) = 78 sq. inches. Referring to chart 78

Temperature Regulation
Due to the nature of the typical gas water heater, the water tem-
perature in certain situations may vary up to 30°F higher or
Iower at the point of use such as, bathtubs, showers, sink, etc.
This means that when the temperature adjustment dial is set at
the markapproximating 120" F, the actual water temperature at
any hot water tap could be ashigh as 150°F oras low as 90"E
Any water heater's intended purpose is to heat water. Hot water
is needed for cleaning (bodies, dishes, clothing). Hot water will
present a scald hazard. Depending on the time dement, and the
people involved (normal adults, children, toddlers, elderly,
infirm, etc.) scalding may occur at different temperatutes.
