INJURY, OR PROPERTY DAMAGE. Refer to this manu-
al for assistance or consult your local Sears Service
Center for further information.
_,WARNING
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
use the correct gas can cause problems which can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAHAGE. If you have any questions or doubts consul
your gas supplier or local utility.
_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 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 anyone 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 e_evated 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 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.
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance.
_WARNING
if this water heater wlll 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 "Facts to Consider About the
Location" section of this manual and also the latest edi-
tion of the National Fuel Gas Code, ANSI Z223.1, also
referred to as NFPA 54 for specifics provided concerning
air required.
I AWARNING
A fire can start if co_ials such as clothing,
cleaning materials, or flammable liquids are placed against
or next to the water heater.
&WARNING
At the time of manufacture this water heater was provid-
ed with a combination 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 ASHE. 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 requirements for
Relief Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems, ANSI Z21.22 by a nationally rec-
ognized testing laboratory that maintains periodic
inspection of production of listed equipment or
materials.
The valve must 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 1000 x 3415 equal BTUIHr. 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-
fied 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
_lace 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 provide
tubing so that 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 electrical
part. The discharge opening must not be blocked or
reduced in size under any circumstances. Excessive
length, 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 relief valve and the tank. Do not connect tubing
directly to discharge drain unless a 6" air gap is provided.
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 outlet 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 dis-
charge pipe.
Must terminate at an adequate drain.
Must not have any valve between the relief valve and
tank.
Safety Precautions
_,WARNING
A gas water 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 "Facts to Consider About the Location" sec-
tion. Never obstruct the flow of ventilation air. If you have
any 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 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 satisfy clothes 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 physically/men-
tally handicapped. If anyone using hot water in your home
fits into one of these groups or if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addi-
tion to using the 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
"Temperature Regulation" section in 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, because failure
to correct the cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
_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 is installed
in an alcoveor closet,the entire floor must be coveredb
the panel. Failure to heed this warning may result in
fire hazard.
_,WARNING
VENT DAMPERS - Any vent damper,whether it isoperat-
ed thermally or otherwise must be removed if its use
inhibitsproperdrafting ofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80%may
_roducea relatively low flue gastemperature. Such tem-
peratures may not be highenoughto properlyopen ther-
mally operated vent dampers.This would causespillageof
fluegasesandmay causecarbon monoxide poisoning.
Vent dampers must 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 installation of any vent damper, consult
your local Sears Service Center or the gasutility for fur-
ther information.
_,WARNING
•The appliance and its individualshutoffvalvemust be dis-
connected from the gassupplypiping systemduring any
pressure testing of the gassystem at test pressuresin
excessof ½poundper squareinch(3.5kPa).
• The appliance must be isolatedfrom the gassupplypip-
ing system by closingits individualmanual shutoff valve
during any pressuretesting of the gassupplypiping sys-
tem at test pressuresequal or less than Y2pound per
squareinch(3.5kPa).
_,WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (L.P.) 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 sniffing at 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.
_,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.
AWARNING
Obstructed or deteriorated vent systems may present a
serious health risk or asphyxiation.

Safety Precautions
_WARNING _]
The water heater with draft hood installedmust be 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 I
improper operation, explosionor asphyxiation. |
_,WARNING
Minimum clearancesbetween the water heater and com-
bustibleconstruction are I" 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:
dimensionmay be allowed on some models. Refer to the
labelon the water heater adjacentto the gascontrol valve
for all clearances.
•,WARNING I
Do not use this applianceif any part of it hasbeen under
water. Immediately call a Sears Service Technician to I
inspectthe appliance and to replace the gascontrolor any
part of the burner systemwhich hasbeen underwater.
_,CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplishedin sucha manner
that if the tank or any connectionsshouldleak, the flow of
water will not causedamage to the structure. For this
reason, it isnot advisableto installthe water heater in an
attic or upper floor. When suchlocationscannotbe avoid-
ed, a suitable drain pan should be installed under the
water heater. Drain pansare availableat your local Sears
store. Sucha drain panmustbe not greater than 1%inch-
es deep, have a minimum length and width of at least 2
inches greater than the water heater dimensions and
must be piped to an adequate drain. The pan must not
restrict combustion air flow. Under no circumstancesis
the manufacturer or Searsto be held liablefor any water
damage in connectionwith thiswater heater.
_,WARNING
HYDROGEN GAS:Hydrogen gascanbe 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 andexplosive.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 (suchas a
dishwasheror washing machine). If hydrogen gas is 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 faucet at the time it isopen.
AWARNING
INSULATING JACKETS: When installing an external
water heater insulationjacket on a gaswater heater:
DO NOT coverthe temperature-pressure relief valve.
DO NOT put insulation over any part of the top of the
gaswater heater.
DO NOT put insulationover the gas control valveor gas
control valve/burner cover, or any accessareas to the
burner.
DO NOT let insulation around 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
safetyrelated warning labelsand materials affixedto the
water heater.
:allureto heedthis will result in the possibilityof a fire or
explosion.

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 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.
A CAUTION
WATER HEATERSEVENTUALLY LEAK: Installationof the
water heater mustbe accomplishedin sucha mannerthat if
thetank or anyconnectionsshouldleak,theflowofwater will
not causedamageto the structure.For this reason, it isnot
advisableto installthe water heaterin an atticor upperfloor

ableat your localSearsstore. Sucha drain pan must be not
greaterthan I½ inchesdeelghaveaminimumleng_ andwidth
ofat least2 inchesgreaterthan the water heater dimensions
and must be pipedto an adequatedrain.The pan must not
restrict combustionair flow. Under no circumstancesisthe
manufacturer or Searsto beheld liablefor any water damage
inconnectionwiththis water heater
AWARNING
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.), all of which emit flammable 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 cancausedeath or serious burns to anyone in
the area, aswell asproperty damage.
If installation in suchareas is your only option, then the installa.
tion 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 chancesof flammable vaporsfrom
floor spillbeing ignited,gasolineandother flammable substance!
shouldnever be stored or used in the same room or area con.
raining a gaswater heater or other open flame or sparkproduc-
ingappliance.
NOTE: Flammable vapors may be drawn by air currents from
other areasof the structure to the appliance.
AWARNING
Propellants of aerosol spraysand volatile compounds, (clean-
ers, chlorine based chemicals, refrigerants, etc.) in addition to
being highly flammable in many cases,will also change to cor-
rosive hydrochloric acid when exposed to the combustion :
products of the water heater. The results can be hazardous,
and also cause product failure.
• The location selection must provide adequate clearances for ser-
vicing and proper operation o_'the water heater.
AWARNING
This water heater must not be installed directly on carpeting.
