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 a way 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 gas water
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 installed so 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 Fuel Gas Code, ANSI Z223.1, also referred to as
NFPA 54for specifics providedconcerningairrequired.
_WARNING
A fire can start 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 productionof
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 less than 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 divided by 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 valve model
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
a locally prescribed temperature-prossure relief valve
installedin thedesignated openingin the water heater in
_lace of the 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 of the water heater designatedfor
the relief valve. Position the valvedownward and provide
tubingsothat any dischargewill 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 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 unlessa 6" air gap isprovided.
To prevent bodilyinjury, 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 ofmaterial 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 have any valve between the relief valve and
tank.

Safety Precautions
a,WARNING
A gas water heater cannot operate properlywithout 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 youhaveany
doubts or questionsat all, call your gascompany.Failure
to providethe proper amount ofcombustionair can result
in a fire or explosion and can cause DEATH, SERIOUS
BODILY INJURY,OR PROPERTY DAMAGE.
_,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 likely to
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 law requiring a certain temperature water at the hot
water tap, then you must take specialprecautions.In addi-
tion to usingthe lowestpossibletemperature settingthat
satisfiesyour hot water needs, a means such asa mixing
valve,shouldbe usedat the hot water taps usedby these
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.
_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 any direction, or ifthe appliance isinstalled
in an alcoveor closet,the entire floor must be covered by
the panel. Failure to heed this warning may result in a
fire hazard.
_,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 local Sears Service Center or the gasutility for fur-
ther information.
AWARNING
• The appliance and its individualshutoffvalvemust bedis-
connectedfrom the gassupplypipingsystemduring any

AWARNING
HYDROGEN GAS:Hydrogengascan be producedin a hot
water system that has not 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 appliances which are
connected to the hot water system are used (such as a
dishwasheror washing machine). If hydrogengasis pre-
sent, there will probablybe an unusualsoundsimilarto 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.
• ,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, a suitable drain pan should
be installedunder 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
INSULATING JACKETS: When installing an external
water heater insulationjacketon a gaswater 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 insulationaround the gaswater heater to
get within 8 inches of the floor (air must get to the
burner).
• DO NOT cover or remove operating instructions, and

Facts to Consider About the
Location
You should carefully choose an indoor location for the new
water heater, because the placement is a very 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 sucha mannerthat if
