AWARNING
WATER HEATERS EQUiPPED FOR ONE TYPE GAS
ONLY: This water heater is equipped for one type gas
oniy. Check the modei 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 resuit in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
your gas supplier or locai utility.
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 of which emit flammabie
vapors, may be improperiy stored or used in such areas.
The gas vrater 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 weil 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, gasoiine
and other flammabie subst»ices should never be stored or
used in the same room or area containing a gas water
heater or other open flame or spark producing appiiance.
NOTE: Flammable vapors may be drawn by air currents
from other areas of the structure to the appliance.
AWARNING
If this water heater will be used in beauty shops, barber
shops, cieaning estabiishments, 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 ventiiation 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.
AWARNING
A fire can start if combustible materials such as clothing,
cieaning materials, or flammable liquids are placed against
or next to the water heater.
_______________
^
AWARNING
At the time of manufrcture this water heater was provid
ed with a combination temperature-pressures relief valve
certified by alinationaliy recognized testing iaboratory
that maintains periodic inspection of production of iisted
equipment or materiais, as meeting the requirements for
Relief Valves and Automatic Gas Shutoff Devices for Hot
Water Suppiy 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 requirements for
Relief Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems, ANSI Z2I.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 (ISO lbs./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
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 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 bie 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
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,
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 permsmently
injure you upon contact. Some people are more litely to
be permanently Injured by hot water than others. Tliese
include the elderly, children, the infirm, or physically/mentafly handicapped. If anyone using hot water in your home
fits into one of these graups or If there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must tala 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.
AWARNING
Soot build-up indicates a problem titat 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
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
p6.2mm) in any direction, or if the appliance is installed
in an alcove or closet, the entire floor must be covered by
the panel. F^lure to heed this warning may result in a
fire hazard.
AWARNING
VENT DAMPERS - Any vent damper, whether it is operat
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 spillage 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 Z2I.68 (ANSI Z2I.66 & 67. respectively,
cover electrically and mechanically actuated vent
dampers). Before instaJIation of any vent damper, consult
your loc^ Sears Service Center or the gas utility for fur
ther information.
AWARNING
• The appliance and its individual shutoff valve must be dis
connected from tile gas supply piping system during any
pressure testing of the gas system at test pressures in
excess of 'A pound per square inch (3.5kPa).
> The appliance must be isolated from the gas supply pip
ing system by closing its individual manud 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 (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^ pilot or turning on a nea^ electri^ 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. 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 hedth risk or asphyxiation.
Safety Precautions continued on page 4
________________
Safety
AWARNING
The mter 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 asphyxiation.
AWARNING
Minimum clearances between the water heater and com
bustible or non-combustible construction are I" 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 mod
els. 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
inspect the appliance and to replace the gas control or any
part of the burner system which has been under water.
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
ex^mely 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 dis
hwasher or vnishing machine). If hydrogen gas is 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 foucet at the time it is open.
ACAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the mter heater must be accomplished in such a manner
that if the tank or any connections should leak, the flow of
vrater 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 avail
able at your local Sears store. Such a drain pan must be
not greater than I 'A inches deep, have a minimum length
and width of at least 1 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
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, al» shut “OFF" the gas at each appliance. Leave ^1
gas appliances shut “OFF" until the water heater installa
tion is complete.
Turn “OFF” the water to the water
©
heater. Some installations require that
the water 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 4"
away from where they connect to the
water heater. This will avoid cutting off
the pipes too short. Additional cuts can
be made later if necessary. Disconnect
the temperature-pressure 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 discon
nected and ready to be removed.
Check again to make sure the e« supply
(?)
is “OFF to the water heater. Then dis
connect the gas supply connection from
the gas control valve.
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
trot To avoid being scalded, make 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 wrench at the union in each
line. ATso disconnect the pming remain
ing to the water heater. These pieces
should be saved since they may be need
ed when reconnecting the new water
heater. Disconnea 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.
ACAUTION
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.
