Safety Precautions
▲WARNING
Improper installation, adjustment, alteration, service or
maintenance can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. Refer to this manu-
ai 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
DAMAGE. If you have any questions or doubts consult
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 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 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 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 "Facts to Consider About the
Location" section of this manual and also the latest edi
tion of the National Fuel Gas Code, ANSI Z223.I, also
referred to as NFPA 54 for specifics provided concerning
air required.
▲WARNING
A fire can start if combustible materials such as clothing,
cleaning materials, or flammable liquids are piaced i^nst
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 produrtion 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 Z2I.22 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 iaboratory 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 (ISO 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 BTUAHr. rate.)
Your focal jurisdictional authority, while mandating the
use of a temperature-pressure relief valve complying
with ANSI Z2I.22 and ASME, may require a valve model
different from the one fomished with tiie 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
place 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 pro
vide 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,
lb 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
chaise 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
discharge pipe.
• Must terminate at an adequate drain.
* Must not have any valve between the relief valve and
tank.
Safety Precautions
AWARNING
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,
CPRimiS Rnmiv ikiii inv nn oonDcnrv r\AMA/:!c
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem
perature which wiil satisfy ciothes washing, dish washing,
and other sanitizing needs can scald and permanentiy
injure you upon contact Some peopie are more likeiy to
be permanentiy injured by hot water than others. These
include the elderly, children, the infirm, or physically/mentaily 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
mter tap, tiien 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 tiie thermostat, read the
"lemperature Regulation” section in this manual.
AWARNING
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 Allure
to correct the cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
AWARNING
This water heater must not be installed directly on car
peting. Carpeting must be protected by a metal or wood
panel beneath the applimce 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
ed thermally or otherwise must be removed if its use
inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80% may
produce a relatively low flue gas temperature. Such tem
peratures may not be high enough to properly open ther
mally operated vent dampers. This would cause spill^e of
flue gases and may cause carbon monoxide poisoning.
Vent dampers must bear evidence of certification as com
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 loc^ Sears Service Center or the gas utility for fur
ther information.
—.«V TTtICUI«;i IV l> uperiltk-
AWARNING
* The appliance and its individual shutoff valve must be dis
connect from the gas supply piping system during any
pressure testing of the gas system at test pressures in
excess of /i pound per square inch (3.5kPa).
• The appliance must be isolated from díte gas supply pip
ing system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping sys
tem at test pressures equal or less than 'A pound per
square inch (3.5kPa).
AWARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (LP.) 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.
AWARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustion contains certain chemical
vapors. Spi^ can propellants, cleaning solvents, refHgerator 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 continued on page 4.
Safety Precautions
AWARNING
The water heater with draft hood installed must be prop
erly vented to a chimney which terminates outdoors.
Never operate the water heater unless it is vented to the
outdoors and has adequate air supply to avoid risks of
improper operation, explosion or asphjmiation.
AWARNING
Minimum clearances between the water heater and com
bustible construction are I” at the sides and rear, 4" at the
front, and 6" from the vent pipe. Clearance from the top
of the jactwt is 18" on most models. Note that a lesser
dimension may be allowed on some models. Refer to the
label on the water heater adjacent to the gas control valve
for all clearances.
AWARNING
Do not use this appliance if any part of it has been under
water. Immediately call a Sears Service Technician to
in^Kct the appliance and to replace the gas control or any
part of the burner system which has been under water.
ACAUTION
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. For this
reason, it Is not advisable to install the water heater in an
attic or upper floor. 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 not greater than
11/2 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 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 connection with this water heater.
AWARNING
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 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 unusual sound similar to air
escaping through the pipe as the hot water faucet is
opened. There must be no smoldng or open flame near
the faucet at the time it is open.
AWARNING
INSULATING JACKETS: When installing an external
water heater insulation jacket on a gas water heater:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over any part of the top of the
gas water heater.
• DO NOT put insulation over the gas control valve or gas
control valve/bumer cover, or any access areas to the
burner.
• 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 labels and materials affixed to the
water heater.
Failure to heed this will result in the possibility of a fire or
explosion.

Installation Instructions
Removing the Old Water Heater
^^Turn “OFF” the gas supply to the water heater.
AWARNING
If the main gas line shutoff serving all gas appliances is
used, also shut “off’* the gas at each appliance. Leave all
gas appliances shut “off" until the water heater insolation
is complete.
^^Turn “OFF” the water to the water
'“^heater. Some installations require that
the watet be turned off to the entire
house.
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.
©
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.
{3)Cbeck again to make sure the ^ supply
'■ ^is “OFF to the water heater. Then dis
connect the gas supply connection from
the gas control valve.
(4) Attach a hose to the water heater drain
valve and put the other end in a floor
drain or outdoors. Open the water heater
drain valve. Open a nearby hot water
faucet which will relieve pressure in the
water heater and speed draining.
AWARNING
The water passing out of the drain valve may be extremely
hot. To avoid being scalded, mate sure all connections are
tight and that the water flow is directed away from any
person.
b. If you have galvanized pipe to the water
heater, loosen the two galvanized pipes
with a pipe vnrench at the union in each
line. Also disconnect the piping remain
ing to the water heater. These pieces
should be saved since they may be need
ed when reconnecting the new water
heater. 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.
A CAUTION
Mineral buildup or sediment may have accumulated in the
old water heater. This causes the water heater to be much
heavier than normal and this residue, if spilled out, could
cause staining.
Installation Instructions (cont’d)
Facts to Consider About the Location
You should carefully choose an indoor location for the new
wat^ 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 HEATERS EVENTUALLY LEAK: Installation of the
water heater must be accomplished in such a manner that if
the tank or any connections should ieak, the flow of water will
not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an attic or upper floor.
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
not greater titan I '/i inches deep, have a minimum length and
width of at least 2 inches greater than the water heater dimen
sions and must be piped to an adequate drain. The pan must
not restrict combustion air flow. Under no circumstances is the
manufecturer or Sears to be held liable for any water damage
in connection with this water heater.
AWARNING
INSTALLATIONS IN AREAS VWERE FLAMMMLE UQUIDS
(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
improperiy 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 bums to anyone in
the area, as well as property dam^.
If installation in sudi areas 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 thb rnay 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 con
taining a gas water heater or other (q>en flame or qiark produc
ing appliance.
NOTE Flammable vapors may be drawn by ar currents from
other areas of the structure to the appliance.
awarKiing
Propellants of aerosol sprays and 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 expoUd to the combustion
products of the water heater. The results can be hazardous,
and also cause product feilure.
The location selection must provide adequate clearances for ser
vicing and proper operation of the water heater.
AWARNING"^
This heater must not be installed directly on carpeting.
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
Minimum clearances between the water heater and com
bustible construction are I" at the sides and rear, 4" at the
front, wd 6" from the vent pipe, aearance 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 label on the water
heater adjacent to the gas control valve for :dl clearances.

AWARNING
A gas water heater cannot operate properly without the cor
rect amount of air for combustion. Do not install in a confined
area such a closet, unless you provide air as shown in Figures
1-5. Never obstroct the flow of ventilation air. If you have any
doubts or questions at all, call your gas company, fêlure to pro
vide the proper amount of combustion air can result in a fire or
explosion and can cause DEATH, SERIOUS BODILY INJURY
OR PROPERTY DAMAGE
AWARNING
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
wrater heaters be installed so that combustion and ventilation
air be taken from outside these areas. Refer to the “Facts to
Consider About the Location" section of this manual and also
tite latest edition of the National Fuel Gas Code, ANSI Z223.I,
also referred to as NF№ 54 for specifics provided concerning
air required.

Combustion Air and Ventilation
for Appliances Located in
Unconfined Spaces
Unraiifiaed Space is a space whose volume is not less than 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 installei
through openings not furnished with doors, are considered 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 buildmgs of tight construction (for example,
weaker 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, b.

bined space shall be considered in making this determination,
^ch openii^ shall have a minimum free area of one square
inch per 1,000 BT^ per hour of the total input raring 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.
