WATER HEATERS EQUIPPED FOR ONE TYPE GAS
ONLY: This water heater is equipped for one type gas
only. Check the model rating plate near the gascontrol
valve for the correct gas. DO NOT USE THIS WATER
HEATER WITH ANY GAS OTHER THAN THE ONE
SHOWN ON THE MODEL RATING PLATE. Failure to
usethe correct gascan causeproblemswhichcanresultin
DEATH, SERIOUS BODILY INJURY, OR PROPERTY

AWARNING
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 ofwhich emit flammable
vapors, may be improperly stored or used in suchareas.
The gaswater heater pilot light or main burner can ignite
such vapors. The resulting flashback and fire can cause
death or serious burns to anyone in the area, aswell as
property damage.
If installation in such areas is your only option, then the
installation must be accomplishedin a way that the pilot
flame and main burner flame are elevatedfrom the floor
at least 18 inches.While this may reduce the changesof
flammable vaporsfrom a floor spillbeing ignited, gasoline
and other flammable substancesshouldnever be stored or
used in the same room or area containing a gas water
heater or other openflame or spark producingappliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasof the structure to the appliance.
_,WARNING
If this water heater will be used in 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 installed so that com-
bustion 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
i National FuelGas Code, ANSI Z223.1, also referred to as
INFPA 54 for specificsprovidedconcerningairrequired.
_,WARNING I
A E_ can start if combustiblematerials suchas clothing,I
cleaningmaterials, or flammable liquidsare placedagainst
or next to the water heater.
_,WARNING
At the time of manufacture thiswater heater wasprovid-
ed with a combination temperature-pressurosrelief vaive
certified by a nationally recognized testing laboratory
that maintains periodic inspectionof production of listed
equipment or materials, as meeting the requirements
for Relief Valvesand 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 lessthan a combination temperature and
pressure relief valve certified as meeting the require-
ments for Relief Valves and Automatic Gas Shutoff
Devicesfor Hot Water SupplySystems,ANSI Z21.22 by
a nationally recognized testing laboratory that maintains
periodic inspectionof production of listed equipment or
materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostaticworking pressure
of the water heater (150 Ibs./sq. in.) and a discharge _
capacity not lessthan the water heater input rate as
shown on the model rating plate. (Electric heaters -
watts dividedby 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 furnishedwith the water heater.
Compliance with suchlocal requirements must be satis-
fied by the installer or end user ofthe water heater with
a locally prescribed temperature-pressure relief valve
installedin the designatedopeningin the water heater in
placeof the factory furnishedvalve.
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 into the fitting of the water heater designated
for the relief valve. Positionthe valvedownward and pro-
vide tubing so that 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.
Excessivelength, over 30 feet, or useof more than four
elbows can cause restriction and reduce the discharge
capacityofthe 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 discharge water
in quantities should circumstances demand. If the dis-
charge pipe is not connected to a drain or other suitable
means, the water flow may causeproperty damage.
The DischargePipe:
Must not be smaller in sizethan the outlet pipe size of
the valve, or have any reducing couplings or other
restrictions.
Must not be pluggedor blocked.
Must be of material listedfor hot water distribution.
Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the
dischargepipe.
Must terminate at an adequatedrain.
Must not have any valve between the relief valve and
tank.
Safety Precautions
AWARNING
A gas water heater .cannotoperate properly without the
correct amount of mr 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
doubtsor questionsat all, call your gascompany. Failure
to providethe proper amount of combustionair can result
in a fire or explosion and can cause death, seriousbodily
injury,or property damage.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfyclotheswashing,dish washing
and other sanmzing needs can scald and permanently
injure you uponcontact. 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.Ifanyone usinghot water in your home
fits into one of these groupsor if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take specialprecautions.In addi-
tion to usingthe lowestpossibletemperature setting that
satisfiesyour hot water needs,a means suchas a mixing
valve, should be used at the hot water taps usedby these
people or at the water heater. Mixingvalvesare 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"sectioninthis manual.
_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 if the appliance isinstalled
in an alcoveor closet,the entire floor must becoveredby
the panel. Failure to heed this warning may result in a
fire hazard.
_,WARNING
The power vent water heater requiresits own (separate)
ventingsystem.It cannot be connectedto an existing vent
pipeor chimney.It must beterminated horizontallyto the
outdoors.Failureto properly installthe ventingsystem can
result in asphyxiation, a fire or explosion and can cause
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE.
AWARNING
No vent damper installationis compatible with this power
vented water heater design.No vent damper, whether it is
operated thermally or otherwise is to be installed on this
power vented water heater. Alteration of any part of the
factory-furnished ventassemblycouldresultin improperop-
eration dueto restriction offlue gases,spillageoffluegases
and may causecarbon monoxide poisoning.
_,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
explosioncausingdeath, seriousbodily injury,or property
damage.
AWARNING
BEFORE LIGHTING [PROPANE (L.R) GAS WATER
HEATERS]: Propane (L.R) gasis heavier than air. Should
there be a leak in the system,the gaswill settle near the
ground. Basements, crawl spaces, skirted areas under
mobile homes (even when ventilated), closets and areas
belowground levelwill serve as pocketsfor the accumula-
tion of this gas. Before attempting to light or relight the
water heater's pilot or turning on a nearbyelectrical light
switch, be absolutely sure there is no accumulated gasin

Jerly vented to a chimney which terminates outdoors. I
I Never operate the water heater unlessit is vented to the J
outdoors and has adequate air supply to avoid risks of J
Jimproper operation,explosionor asphyxiation.
AWARNING
Minimum clearancesbetween the water heater and com-
bustibleconstructionare I" at the sidesandroar, 4" at the
front, and 6" from the vent pipe. Clearance from the top
of the jacket is 18" on most models. Note that a lesser
dimension may be allowed on some models. Refer to the
labelon the water heater adjacent to the gascontrol valve
for all cleerance_
_WARNING I
Do not usethis applianceif any part of it hasbeen under J
Jwater. Immediately call a Sears Service Technician to J
inspectthe applianceandto replace the gascontrol or any
part ofthe burner systemwhich hasbeen under water. J
I AWARNING J
Vent termination must not be within 4 feet of any items J
such as gas meters, gas valves or other gas regulating J
equipment. I
ACAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin sucha manner
that ifthe tank or any connectionsshould leak,the flow of
water will not causedamageto the structure. When such
locations cannot be avoided a suitable drain pan should
be installed under the water heater. Drain pansare aval-
able at your local Sears store. Such a drain pan must be
not greater than I I/2 inches deep, have a minimum
length and width of at least 2 inches greater than the
water heater dimensionsand must be piped to an ade-
quate 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-
ionwith this water heater.
_E,WARNING
HYDROGEN GAS: Hydrogengascan be producedin a hot
water systemthat has not been usedfor a long period of
time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive. To prevent the possi-
bility of injury under these conditions,we recommend the
hot water faucet be opened for several minutes at the
kitchen sink before any electrical appliances which are
connectedto the hot water systemare used(suchasa dis-
hwasber or washingmachine). If hydrogengasis present,
there will probably be an unusual sound similar 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 insulationjacket ona gaswater heater:
DO NOT cover the temperaturo-prossurerolief valve.
DO NOT put insulation over any part of the top of the
gaswater heater.
DO NOT put insulationoverthe gascontrol valve or 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
safety related warninglabelsand materials affixedto the
water heater.
Failureto heed thiswill result in the possibilityof a fire or
explosion.

the water be turned off to the entire
house,
Q Disconnect the vent pipe from the draft hood where
they connect to the water heater. In most installations
the vent pipe can be lifted off after any screw or other
attached devices are removed. Dispose of the draft
hood. The new water heater has the draft hood which
must be used for proper operation.
G a. If you have copper piping to the water
® ®
heater, the two copper water pipes can
be cut with a hacksaw approximately
four inches away from where they con-
nect to the water heater. This will avoid
cutting off the pipes too short.
Additional cuts can be made later if nec-
essary. Disconnect the temperature-pres-
sure relief valve drain line. When the
water heater is drained, disconnect the
hose from the drain valve. Close the
drain valve. The water heater is now
completely disconnected and ready to be
removed.
QCheck again to make sure the gas supply
is "OFF" to the water heater. Then dis-
connect the gas supply connection from
the gas control valve.
Q Attach a to water heater drain

Installation Instructions
Locating the New Water
Heater
You should carefully choose an indoor location for the new water
heater, because the placement is a very important consideration
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.
1. The location selected should be indoors as dose as practical
to the vent termination point, 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 provisions where water flow will cause damage.
2. The vent piping cannot exceed a total of 35 feet including
vertical and horizontal runs and have no more than 3 elbows.
It cannot slope downward and horizontal runs require ¼" per
foot rise. All horizontal runs require adequate support at 3½
feet intervals.
3. The water heater requires its own (separate) venting system.
It cannot be connected to an existing ventpipe or chimney.
It must terminate horizontally to the outdoors. Whenever
possible terminate the vent on the leaward side of the build-
ing. NOTE: Condensation may be created, at times, as the
combustion gases exit the vent cap and discoloration of
surfaces in proximity to the vent cap may occur.
AWARNING

Installation Instructions (cont'd)
Combustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Unconfined Space is a spacewhose volume is not lessthan 50 cubic
feet per 1,000 Btu per hour of the aggregateinput rating of allappli-
ances installed in that space. Rooms communicating directly with the
space in which the appliancesareinstalled, through openingsnot fur-
nishedwith doors, areconsidereda part of the unconfined space.
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, heavilyinsulated, caulked, vapor barrier, etc.), additionalair
may need to be provided using the methods describedin Combustion
Air and Ventilation for Appliances Locatedin Confined Spaces.
Combustion Air and Ventilation
1. When directly communicating with the outdoors, each opening
shall have a minimum free area of 1square inch per 4,000 BTU
per hour of total input rating of all equipment in the enclosure.
(SeeFigure6.)
2. When communicating with the outdoorsthrough vertical ducts,
each opening shall have a minimum free areaof I square inch
per 4,000 BTU per hour of total input rating of allequipment in
the enclosure. (SeeFigure7.)
VENTILAT_ LO_I:_
for Appliances 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:
(See Page 8 Figure 1, and Figure 5 below)
The confined space shall be provided with two permanent open-
ings communicating directly with an additional room(s) of suffi-
cient volume so that the combined volume of all spaces meets the
criteria for an unconfined space. The total input of all gas utiliza-
tion equipment installed in the combined 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 rating of 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.
I Figure 5 [
b. ALL AIR FROM OUTDOORS: (see Figures 6-8)
The confined space shall be provided with two permanent open-
ings, one commencing within 12 inches of the top and one com-
mencing within 12 inches from the bottom orthe enclosure.
The openings shall communicate directly, or by ducts, with the
outdoors or spaces (crawl or attic) that freely communicate with
the outdoors.

3. When communicating with the outdoors through horizontal
ducts, each openingshall have a minimum free area of 1 square
inch per 2,000 BTU per hour of total input rating of all equip-
ment in the enclosure. (SeeFigure8.)
Figure 8 1
4. When ducts are used, they shall be of the same cross-sectional area
as the free area of the openings to which they connect. The mini-
mum short side dimension of rectangular air ducts shall nor be
less than 3 inches. (See Figure 8.)
5. Louvers and Grilles: In calculating free area, consideration shall be
given to the blocking effect of louvers, grilles or screens protect-
ing openings. Screens used shall not be smaller than ¼ inch mesh.
If the free area through a design of louver or grille is known, it
should be used in calculating the size opening required to provide
the free area specified. If the design and free area is not known, it
may be assumed that wood louvers will be 20-25 percent free area
and metal louvers and _rilles will have 60-75 percent free area.
Louvers and .grilles shall be fixed in the open position or inter-
locked with the equipment so that they are opened automatically
during equipment operation.
6. Special Conditions Created b7 Mechanical Exhausting or
Fireplaces: Operation of exhaust fans, ventilation systems, clothes
dryers or firefplaces may create conditions requiring special atten-
tion to avoica unsarisfactory operation of installed gas utilization
eqmpment.
