WARNING
At the time of manufacture this water heater was provided with
a combination temperature-pressure relief valve c:ertifled by a
nationally recognized testing laboratory that maintains periodic
inspection of production of listed equipment or materials, 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 cove requirements of ASME. If
replaced, the valve must meet the requirements of local codes,
but not Jessthan a combination temperature and pressure reJief
valve certified as meeting the requirements for Relief Valves
and Automatic Gas Shutoff Devices for Hot Water Supply
Systems,ANSI Z21.22 by a nationaJly recognized testing labo-
ratory that maintains _eriodic inspection of production of listed
equipment or materials.
T_e valve must be marked with a maximum set pressurenot 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 ratin_
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
furnishedwith the water heater.
Compliance with such local requirements must be satisfied by
the installer or end user of the water heater with a locally pre-
scribedtemperature-pressure reJiefvalve installed in the desig-
nated opening in the water heater in place of the factory fur-
nishedvalve.
For safeoperation of the water heater, the relief valve must not
be removed from it's designatedopening or pJugged.
The temperature-pressure reJiefvalve mustbe i_n_stalleddirectly
into the fitting of the water heater designated for the relief
valve. Position the valve downward and provide tubing sothat
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 live eJectrica]part. The discharge opening
must not be blocked or reducedln size under any ctrcum-
stances.Excessive length, over 30 feet, or useof 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
dischargedrain unlessa 6_air gap is provided. To prevent bod-
ily injury, hazard to life, or property damage, the relief valve
must be allowed to discharge water in quantities should clr-
cumstances demand. If the discharge pipe is not connected to
a drain or other suitable means, the water fJow 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 couplingsor 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 andtank.
WARNING
WATER HEATERSEQUIPPED FOR ONE TYPE GAS ONLY: This
water heater is equippedfor one type gasonly. Check the model
rating plate near the gas control valve for the correct gas. DO
NOT USETHIS WATER HEATERWITH ANY GAS OTHER THAN
THE ONE SHOWN ON THE MODEL RATING PLATE.Failure t_
use the correct gas can cause problems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTYDAMAGE. It
loOUhave any questions or doubts consult your gas supplier or
cal utility.
WARNING
Afire can start if combustiblematerialssuchas clothing,cleaning
materials, or flammable liquids are placed againstor next to the
water heater.
WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS)ARE LIKELYTO BE PRESENTOR STORED (GARAGES,
STORAGE,AND UTILITY AREAS,ETC): Flammable liquids (such
as gasoline, solvents,propane (LP) or butane, etc.), all of which
emit flammablevapors, may be improperly storedor used in such
areas. The gaswater heater pilot fight or main burner can i_nite
suchvapors. The resultingflashback and fire can causedeath or
seriousburnsto anyonein the area, aswell asproperty damage.
If installation in such areas is your only option, then the
installation must be accomplished in a way that 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.
NOTE: Flammable vapors may be drawn by air currents from
otherareasof the structure to the appliance.
WARNING
HOTTERWATERCAN SCALD:Water heatersare intendedto pro-
duce hot water. Water heatedto a temperaturewhich will satisfy
clothes washing, dish washing, and other sanitizing needs can
scaldand permanently injure you upon contact. Somepeople are
more likely to be permanently injured by hot water than Others.
Theseinclude the elderly, children, the infirm, or physically/men-
tally, handicapl_ped.If anyone,usinghot.water coa_e_inour home fits
Into one of these groups or If there is a local or state law
requiring a certain temperature water at the hot water tap, then
you musttake special precautions. In addition to usingthelowest
possibletemperature settin_ that satisfiesyour hot w-aterneeds,
sometype of tempering device, suchas a mixingvalve, shouldbe
usedat the hot water tapsused by thesepeople or at the water
heater. Mixing valves are available at plumbing supply or hard-
ware stores.Follow manufacturers instructionsfor installation of
the valves.Before changingthe factory settingon the thermostat,
read the "Temperature Regulation"sectionin this manual.
WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]:
Propane(L.P.)gasis heavierthan air. Shouldthere be a leak in the
system, the gas will settle near the ground. Basements, crawl
spaces,skirtedareasunder mobile homes(even when ventilated),
closetsand areasbelow groundlevel will serveas pocketsfor the
accumulationof this gas.Beforeattempting to light or relight the
water heater's pilot or turnin_ on a nearby electrical light switch,

and sodium chloride, waxes, bleach, and process chemicals
are typical compoundswhich are potentially corrosive.
WARNING
Minimum clearancesbetween thewater heater and combustible
constructionare 1'*at the sidesand rear, 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 dlmension may be allowed on
some models. Refer to the label on the water Eeater attached
adjacentto the gascontrol valve for all clearances.
WARNING
HYDROGEN GAS: Hydrogen gas can be produced in 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 possibility 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 connected to the hot water
systemare used (such as a dishwasher or washing machine). If
hydrogen gas is present, there will probably be an unusual
soundsimilar to air escaping through the pipe asthe hot water
faucet is opened. There must be no smoking or open flame
near the faucet at the time it is open.
WARNING
INSULATING JACKETS: When installing an external water
heater insulation jacket on agaswater heater:

CAUTION

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 homesor
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 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 connecHons 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 no greater than 1% inches deep, have a mmP
mum length and width of at least 2 inclies 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
light or main burner can ignite such vapors. The resulting
flashback and fire can cause death or serious burns to any-
one in the area, as well as property damage.
If installation in such areas is your only option, then the
installation must be accomplished in a way that 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 spark producing appliance.
Also, the water heater must be located and/or protected so
it is not subject to physical damage by a moving vehicle.
NOTE: Flammable vapors maybe 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, will
also change to corrosive hydrochloric acid when exposed
to the combustion products of the water heater. The
results can be hazardous, and also cause product failure.
2. The location selection must provide adequate clearances
for servicing and proper operation of the water heater.
WARNING
This water heater must not be installed directly on carpet-
ing. Carpeting must he protected by a metal or wood panel
beneath the appliance extending be}_ondthe 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 1" at the sides and rear, 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 dimen-
sion may be allowed on some models. Refer to the label on
the water heater attached 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 gas company or Sears Service Center. Failure to pro-
vide the proper amount of combustion air can result ,'n a
fle or explosion and can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE.
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 combus-
tion 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 54 for
specifics provided concerning air required.

_'ombustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Unconfined Space is a space whose volume is not lessthan 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
fn 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.
Combustion Air and Ventilation
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 2 below)
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 determina-
tion. 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 shal] com-
mence within 12 inches of the top and one commencing
within 12 inches of the bottom of the enclosure.
1. When directly communicating with the outdoors, each
opening shall have a minimum free area of 1 square inch
per 4,000 BTU per hour of total input rating of all equip-
ment in the enclosure. (See Figure 3.)
2. When communicating with the outdoors through vertical
ducts, each opening sha[t have a minimum free area of 1
square inch per 4,000 BTU per hour of total input rating
of all equipment in the enclosure. (SeeFigure 4.)

3. When communicating with the outdoors through horizon-
tal ducts, eachopening sh_.llhave a minimum free area of
1 square inch per 2,000 BTU per hour of total inputrating
of all equipment in the enclosure. (SeeFigure5.)

b. ALL AIR FROM OUTDOORS: (see Figures 3-5)
The confined space shall be provided with two perma-
nent openings, one commencing within 12 inches of the
top and one commencing within 12 inches from the bot-
tom of the enclosure. The openings shall communicate
directly, or by ducts, with the outdoors or spaces (crawl or
attic) that freely communicate with the outdoors.
Figure5 I
4. When ducts are used, they shall be of the same cross-sec-
tional area as the free area of the openings to which they
connect. The minimum short side dimension of rectangular
air ducts shall not be less than 3 inches. (See Figure 5.)
5. Louvers and 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 '/4 inch mesh. If the free area through a design
of louver or grille is known, it should be used in calculat-
ing the size opening required to provide the free area spec-
ified. 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 griIIes will have 60-75 percent free
area. Louvers and grilles shall be fixed in the open position
or interlocked with the equipment so that they are opened
automatically during equipment operation.
6. Special Conditions Created by Mechanical Exhausting or
Fireplaces: Operation of exhaust fans, ventilation systems,
clothes dryers or firepJaces may create conditions requiring
special attention to avoid unsatisfactory operation of
installed gas uti]ization equipment.
