AWARNING
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 gas control
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 gas cancause problems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
your gassupplier or localutility.
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 of which emit flammable
vapors, may be improperly stored or used in suchareas.
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 anyone in the area, as well as
property damage.
If installation in such areas is your only option, than 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 chances of
flammable vapors from a floor spill being ignited, gasoline
and other flammable substancesshould never be stored or
used in the same room or area containing a gas water
heater or other open flame or spark producing appliance.
NOTE: Flammable vapors may be drawn by air currents
from other areasof the structure to the appliance.
A, WARNING
If this water heater will be used in beauty shops, barber
shops, cleaning establishments, or serf-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
National Fuel Gas Code, ANSI 7.223.1, also referred to as
NFPA 54 for specificsprovided concerning air required.
I _,WARNING
A fire can start if co_Hals suchasclothing,
cleaningmaterials,or flammableliquidsam placedagainst
or nexttothe waterheater.
AWARNING
At the time of manufacture this water heater was provid-
ed with a coml_nation temperature-pressures relief valve
certified 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 Shutoff Devices for
Hot Water Supply Systems, and the latest edition of
ANSI Z21.2Z and the code requirements of ASME. If
replaced, the valve must meet the requirements of local
codes, but not less than a combination temperature and
pressure relief valve certified as meeting the require-
ments for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems, ANSI Z21.22 by
a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials.
The valve must be marked with a m_imum 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 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 furnished with the water heater.
Compliance with such local requirements must be satis-
fled by the installer or end user of the water heater with
a locally prescribed temperature-pressure relief valve
installed in the designated opening in the water heater in
dace of the factory furnished valve.
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. Position the valve downward and pr_
vide tubing so that any discharge will exit only within
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 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 re ef vave and the tank. Do not connect tub ng
directly to discharge drain unlessa 6" air gap isprovided.
To prevent bodily injury, 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 cause property damage.
The Discharge Pipe:
Must not be smaller in size than the oudet pipe size of
the valve, or have any reducing couplings or 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 and
tank.

Safety Precautions
AWARNING
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
shown in the "Locating The Now Water Heater" section.
Never obstruct the flow of ventilation air. If you haveany
doubts or questions at all, call your gas company. Failure
to provide the proper amount of combustion air can result
in a fire or explosion and can cause DEATH, SERIOUS
BODILY INJUR_, OR PROPERTY DAMAGE.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
mraturo which will satisfyclothes washing, dish washing,
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
include the elderly, children, the infirm, or physicaily/mea.
tally handicapped. If anyone using hot water in your home
fits into one of these groups or if there is a local cede or
state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addi-
tion to usingthe lowest possible temperature setting that
satisfies your hot water needs, a means such as a mixing
valve, should be used at the hot water taps used by these
people or at the water heater. Mixing valves are available
at plumbing supply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
'_l'emperatoro Regulation" section in this manual.
i
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 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.
AWARNING
AWARNING
The power vent water heater requires its own (separate)
venting system. It cannot be connected to an existing vent
pipe or chimney. It must be terminated horizontally to the
outdoors. Failure to properly install the ventingsystem can
result in asphyxiation, a fire or explosion and can cause
DEATH, SERIOUS BODILY INJURY,OR PROPERTY DAM-
AGE.
AWARNING
No vent damper installation iscompatible with this power
vented water heater design.No vent damper, whether it is
operated thermally or otherwise isto he installed on this
power vented water heater. Alteration of any part of the fac-
tory-furnished vent assemblycould result inimproper oper-
ation due to restriction of flue gases, spillage of flue gases
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, because failure to
correct the cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
AWARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (I-R) gas is heavier than air. Should
there be a leak in the system, the gas will settle near the
ground. Basements, crawl spaces, skirted areas under
mobile homes (even when ventilated), closets and areas
below ground level will serve as pockets for the accumula-
tion of this gas. Before attempting to light or relight the
water heater's pilot or turning on a nearby electrical light
switch, be absolutely sure there is no accumulated gas in
the area. Search for odor of gas by sniffingat ground level
in the vicinity of the appliance. If odor is detected, follow
steps indicated at "For Your Safety" on the cover page of
this manual then leave the premises.
AWARNING
•The appliance and its individual shutoff valve must be dis-
connected from the gassupply piping system during any
pressure testing of the gas system at test pressures in
excess of I/2 pound per square inch (3.5kPa).
•The appliance must be isolated from the gas supply pip-
ing system by closingits individual manual shutoff valve
during any pressure testing of the gas supply piping sys-
tem at test pressures equal or less than I/2 pound per
square inch (3.SkPa).
_,WARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustion contains certain chemical
vapors.Spray can propellants, cleaning solvents,refrigera-
tor and air conditioner refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes, bleach,
and process chemicals are typical compounds which are
potentially corrosive.
Obstructedor deteriorated vent systemsmay present
serioushealthriskor asphyxiation.

Safety Precautions
&WARNING I
The water heater with draft hood installed must be prep- I
erly vented to a chimney which terminates outdoors. I
Never operate the water heater unless it is vented to the
outdoors and has adequate air supply to avoid risks of
improper operation, expos on or asphyxiation.
_,WARNING
Minimum clearances between the water heater and €om-
bustible construction are 0" at the sidesand rear, 5" at the
front, and 0" from the vent pipe. Clearance from the top
of the jacket is 14" on most models. Note that s lesser
dimension may be allowed on some models. Refer to the
label on the water heater adjacent to the gascontrol valve
for all clearances.
•,WARNING ]
Do not use this appliance if any part of it has been under|
water. Immediately call a Sears Service Technician to|
inspect the appliance and to replace tee gascontrol or any|
part of the bureer system wh ch hasbeen under water. |
AWARNING
HYDROGEN GAS: Hydregen gas canbe 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 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
connected to the hot water system are used (such as a
dishwasher or washing machine). If hydrogen gas is pre-
sent, there will probably be an unusualsound similar to air
escapin_through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucet atthe time it isopen.
I AWARNING ]
Venttermination mustnot be within 4 feet of any items|
suchas gas meters, gasvalvesor other gasregulating|
equipment. |
&,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 pansare avail-
able at your local Sears 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-
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-
tion with this water heater.
AWARNING
INSULATING JACKETS: When instailin S an external
water heater insulation jacket on a gaswater heater:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over any part of the top of the
gaswater heater.
• DO NOT put insulation over the gascontrol valve or gas
control vaivefbumer cover, or any access Meas to the
burner, i
DO NOT let insulation around the gas water 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 warning labelsand materials affixed to the
water heater.
:allure to heed thiswill result in the possibilityof afire or
explosion.

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. TI_ water heater is not for
me 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 close as practical
to the vent termination point, and as centralized with the
water piping system as possible, The water heater, as all water
heaters, willeventually 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 mot 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 _it the vent cap and discoloration of
surfaces in proximity to the vent cap may occur.

4. The water heater comes equipped with a 5 foot power cord
which can be used to connect to a 110/120 volt power
source if(l) local codes allow, and (2) there is a three prong
receptacle available.
5. The location selection must provide adequate dearances for

Combustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Uncom°med Space is a space whose volume is not less than 50 cubic
feet per 1,000 Btu per hour of the aggregateinput rating of allappli-
ances installed in that space. Rooms communicating directly withthe
space in which the%.pphancesareinstalled, through openingsnot fur-
nished with doors, areconsidered a 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, heavily insulated, caulked, vapor barrier, etc.), additional air
may need to be provided using the methods described in Combustion
Air and Ventilation forAppliances Located in Confined Spaces.
Combustion Air and Ventilation
for Appliances Located in
Confined Spaces
Confined Space isa 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 Page8 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 areaof 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 openingshall commence
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 areaof I square inch per 4,000 BTU
_serhour of total input rating of allequipment in the endosure.
ee Figure 6.)
2. When communicating with the outdoors through vertical ducts,
each opening shall 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. (See Figure7.)

Figure 7 1
3. When communicating with the outdoors through horizontal
ducts, each openingshall have a minimum freeareaof 1 square
inch per 2,000 BTU per hour of total input rating of all equip-
ment in the enclosure.(SeeFigure8.)

b. ALL AIR FROM OUTDOORS: (seeFigures6-8)
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 of the enclosure.
The openings shaft communicate directly, or by ducts, with the
outdoors or spaces (crawl or attic) that freely communicate with
the outdoors.
Figure 6 ]
Figure 8 ]
4. When ductsare used, they shallbe of the same cross-sectional area
as the freearea of the openings to which they connect. The mini-
mum short side dimension of rectangularair ducts shall not be
less than 3 inches. (SeeFigure 8.)
5. Louvers and Grilles: In calculating freearea,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 requiredto provide
the free areaspecified. If the design and free areais not known, it
may be assumed that wood louvers will be 20-25 percent freearea
and metal louvers and grilles will have 60-75 percent free area.
Louvers andgrilles shall be fixed in the open position or inter-
locked with the equipment so that they areopened automatically
during equipment operation.
6. Special Conditions Created by Mechanical Exhausting or
Fireplaces:Operation of exhaust fans, ventilation systems, clothes
dryers or fireplaces may create conditions requiringspecial atten-
tion to avoidunsatisfactory operation of installed gas utilization
equipment.

This waterheater shall not be connected to any heating systems
or component(s) used with a non-potable water heating appli-
ance.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve,water
meter with a check valve,etc.., in the cold watersupply; means
shall be provided to control thermal expansion. Contact the
local utility orlocal.SearsServiceCenter on how to control this
situation.
NOTE: To protect against untimely corrosion of hot and
cold water fittings, it b strongly recommended that dielec-
tric unions or couplings be installed on this water heater
when connected to copper pipe.
2. Look at the top cover of the water heater. The cold water
inlet is marked-cold. Put two or three turns of teflon tape
around the threaded end of the threaded-tu-sweat coupling
and around bothends of the _Athreaded nipple. Usingflexi-
ble connectors, connect the coldwaterpipe to the coldwater
inlet of the water heater.
NOTE: This water heater is insulated to minimize heat
loss from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.
