INSTALLATION INSTRUCTIONS
4. Attach a hose to the water heater
Removing the Old 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. The water
passing out of the drain valve may
be extremely hot. To avoid being
scalded, make sure all connections
are tight and that the water flow is
directed away from any person, see
Figures 2 and 5.
FIGURE 5.
5. Disconnect the vent pipe from the draft hood where it connects
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 a draft hood which must be used for proper operation.
6. 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 connect to the water heater,
see Figure 6. This will avoid cutting off 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
disconnected and ready to be removed.
FIGURE 2.
1. Turn “OFF” the gas supply to the
water heater.
If the main gas line Shut-off valve
serving all gas appliances is used,
also shut “OFF” the gas at each
appliance. Leaveallgasappliances
shut “OFF” until the water heater
installation is completed, see
Figures 2 and 3.
FIGURE 6.
FIGURE 3.
If you have galvanized pipes to the water heater, loosen
the two galvanized pipes with a pipe wrench at the union
in each line. Also disconnect the piping remaining to the
water heater, see Figure 7. These pieces should be saved
since they may be needed when reconnecting the new water
heater. 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 disconnected and ready
to be removed. 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.
2. Turn “OFF” the water supply to
the water heater at the water shut
off valve or water meter. Some
installations require that the water
be turned off to the entire house,
see Figures 2 and 4.
FIGURE 4.
3. Check again to make sure the gas supply is “OFF” to the water
heater. Then disconnect the gas supply connection from the
gas control valve.

Facts to Consider About the Location
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. This water heater is not for use in
manufactured (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:
•
Select a location 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.
•
Selected location must provide adequate clearances for
servicing and proper operation of the water heater.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS
(VAPORS) ARE LIKELY TO BE PRESENT OR STORED
(GARAGES, STORAGEAND UTILITYAREAS, ETC.): Flammable
liquids (such as gasoline, solvents, propane [LP or butane, etc.]
and other substances such as adhesives, etc.) emit flammable
vapors which can be ignited by a gas water heater’s pilot light or
main burner. 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.
Installation of the water heater must be accomplished in such a
manner that if the tank or any connections should leak, the flow
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 metal drain pan should
be installed under the water heater. Metal drain pans are available
at your local Sears or hardware store. Such a metal drain pan must
have a minimum length and width of at least 2 inches (51 mm)
greater that the water heater dimensions and must be piped to an
adequate drain. The pan must not restrict combustion air flow.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a metal drain pan
piped to a drain. However, unanticipated damage can be reduced
or prevented by a leak detector or water shut-off device used
in conjunction with a piped metal drain pan. These devices are
available from some plumbing supply wholesalers and retailers,
and detect and react to leakage in various ways:
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
• Sensors mounted in the metal drain pan that trigger an alarm
or turn off the incoming water to the water heater when leakage
is detected.
• Sensors mounted in the metal drain pan that turn off the water
supply to the entire home when water is detected in the metal
drain pan.
• Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water pipes
connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.

This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3 inches (76.2 mm) 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.
FIGURE 9.
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 combustion and ventilation
air be taken from outside these areas.
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.
Minimum clearances between the water heater and
combustible construction are 0 inch at the sides and rear,
4 inches (102 mm) at the front, and 6 inches (153 mm) from the
vent pipe, see Figure 8. Clearance from the top of the jacket is 12
inches (305 mm) on most models. Note that a lesser dimension
may be allowed on some models, refer to the label attached
adjacent to the gas control valve on the water heater.
Insulation Blankets
Insulation blankets available to the general public for external
use on gas water heaters are not necessary with Kenmore
products. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank heaters. Your
Kenmore water heater meets or exceeds the EPACT standards
with respect to insulation and standby loss requirements, making
an insulation blanket unnecessary.
FIGURE 8.
WARNING
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions (See Figure 1 for
identification of components mentioned below). Failure to follow
these instructions can restrict the air flow required for proper
combustion, potentially resulting in fire, asphyxiation, serious
personal injury or death.
A gas water heater cannot operate properly without the correct
amount of air for combustion, see Figure 9. Do not install in a
confined area such as a closet, unless you provide air as shown
in the Combustion Air and Ventilation for Appliances Located in
Confined Spaces section. Never obstruct the flow of ventilation
air. If you have any doubts or questions at all, call your gas
supplier. Failure to provide the proper amount of combustion air
can result in a fire or explosion and cause death, serious bodily
injury, or property damage.
•
•
•
Do not apply insulation to the top of the water heater, as this
will interfere with safe operation of the draft hood.
Do not cover the outer door, thermostat or temperature &
pressure relief valve.
Do not allow insulation to come within 2” (50.8 mm) of the floor
to prevent blockage of combustion air flow to the burner.

B. ALL AIR FROM OUTDOORS: (See Figures 9, 11,12 and 13)
•
•
•
Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
The confined space should be provided with two permanent
openings, one commencing within 12 inches (30 cm) of the top
and one commencing within 12 inches (30 cm) from the bottom
of the enclosure. The openings should communicate directly, or
by ducts, with the outdoors or spaces (crawl or attic) that freely
communicate with the outdoors.
Do obtain new warning and instruction labels from Sears for
placement on the blanket directly over the existing labels.
Do inspect the insulation blanket frequently to make certain
it does not sag, thereby obstructing combustion air flow.
Combustion Air and Ventilation for
Appliances Located in Unconfined Spaces
UNCONFINED SPACE is space whose volume is not less than
50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) 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.
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 for Appliances
Located in Confined Spaces.
FIGURE 11.
•
When directly communicating with the outdoors, each opening
should have a minimum free area of 1 square inch per 4,000
Btu per hour (5.5 cm2/kW) of total input rating of all equipment
in the enclosure, see Figure 12.
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 (4.8 m3 per kW) of the
aggregate input rating of all appliances installed in that space.
A. ALL AIR FROM INSIDE BUILDINGS:
(See Figure 9 and Figure 10)
The confined space should 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
combined space should be considered in making this
determination. Each opening should have a minimum free
area of one square inch per 1,000 Btu per hour (22 cm2/
kW) of the total input rating of all gas utilization equipment
in the confined space, but not less than 100 square inches
(645 cm2). One opening should commence within 12 inches
(30 cm) of the top and one commencing within 12 inches (30
cm) of the bottom of the enclosures.
FIGURE 12.
•
•
•
When communicating with the outdoors through vertical
ducts, each opening should have a minimum free area of
1 square inch per 4,000 BTU per hour (5.5 cm2/kW) of
total input rating of all equipment in the enclosure, see
Figure 12 on page 11.
When communicating with the outdoors through horizontal
ducts, each opening should have a minimum free area
of 1 square inch per 2,000 BTU per hour (11 cm2/kW) of
total input rating of all equipment in the enclosure, see
Figure 14.
Alternatively a single permanent opening may be used when
communicating directly with the outdoors, or with spaces that
freely communicate with the outdoors. The opening should
have a minimum free area of 1 square inch per 3,000 BTU
per hour (8.3 cm2/kW) of total input rating of all equipment in
enclosure. See Figure 13.

Water Piping
FIGURE 13
•
When ducts are used, they should be of the same cross-
sectional area as the free area of the openings to which they
connect. The minimum short side dimension of rectangular
air ducts should not be less than 3 inches (76.2 mm), see
Figure 14.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water
heated to a temperature which will satisfy space heating,
clothes washing, dish washing, cleaning 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/mentally 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 addition 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, see Figure 15 below. Valves for reducing
point of use temperature by mixing cold and hot water
are also available. Follow manufacturer’s instructions
for installation of the valves. Before changing the factory
setting on the thermostat, read the Temperature Regulation
section in this manual.
FIGURE 14.
•
Louvers and Grilles: In calculating free area, consideration
should be given to the blocking effect of louvers, grilles or
screens protecting openings. Screens used should not
be smaller than 1/4 inch (6.4 mm) mesh. If the free area
through a design of louver or grille is known, it should be
used in calculating the size opening required to provide
the free area specified. 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 grilles will have
60-75 percent free area. Louvers and grilles should be
fixed in the open position or interlocked with the equipment
so that they are opened automatically during equipment
operation.
FIGURE 15.
•
Special Conditions Created by Mechanical Exhausting or
Fireplaces: operation of exhaust fans, ventilation systems,
clothes dryers or fireplaces may create conditions requiring
special attention to avoid unsatisfactory operation of
installed gas utilization equipment.

TYPICAL INSTALLATION
This water heater should not be connected to any heating
systems or component(s) used with a non-potable water
heating appliance.
All piping components connected to this unit for space
heating applications should be suitable for use with
potable water.
Toxic chemicals, such as those used for boiler treatment should
not be introduced into this system.
Water supply systems may, because of such events as high
line pressure, frequent cut-offs or the effects of water hammer
among others, have installed devices such as pressure
reducing valves, check valves, back flow preventers, etc. to
control these types of problems. When these devices are not
equipped with an internal by-pass, and no other measures are
taken, the devices cause the water system to be closed. As
water is heated, it expands (thermal expansion) and closed
systems do not allow for the expansion of heated water.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater’s temperature-pressure relief valve
is reached, the valve will relieve the excess pressure. The
temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This is an unacceptable
condition and must be corrected. It is recommended that any
devices installed which could create a closed system have a
by-pass and/or the system have an expansion tank to relieve the
pressure built by thermal expansion in the water system. Refer
to the Thermal Expansion section under Troubleshooting Guide
or contact local plumbing authority or local Sears Service Center
on how to control this situation.
FIGURE 16.
NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water connections. Do
not solder the water lines directly to the water connections
on the tank. It will harm the dip tube and damage the tank.
•
Look at the top cover of the water heater. The water outlet is
marked “HOT”. Put two or three turns of teflon tape around
the exposed end of the NPT threaded nipple. Connect the hot
water pipe to the hot water outlet on the water heater. Please
note that adapters may be needed to match existing piping.
•
Look at the top of the water heater. The cold water inlet
is marked “COLD”. Put two or three turns of teflon tape
around the exposed end of the NPT threaded nipple.
Connect the cold water pipe to the cold water inlet of the
water heater. Please note that adapters may be needed
to match existing piping.
NOTE: This water heater is super 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.
Figure 16 shows the typical attachment of the water piping to
the water heater. The 74-gallon model water heater is equipped
with 1” NPT water connections.

Temperature-Pressure Relief Valve
FIGURE 17.
This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
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 inch air gap is provided. To
prevent bodily injury, hazard to life, or property damage, the
relief valve must be allowed to discharge water in quantities
should circumstances demand. If the discharge pipe is not
connected to a drain or other suitable means, the water flow
may cause property damage.
The valve is certified by a nationally recognized
testing laboratory that maintains periodic inspection of
production of listed equipment of materials as meeting
the requirements for Relief Valves for Hot Water Supply
Systems, ANSI Z21.22, CSA 4.4 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 indicated in the above paragraph.
The valve must be marked with a maximum set pressure not
to exceed the marked hydrostatic working pressure of the
water heater (150 psi = 1,035kPa) and a discharge capacity
not less than the water heater input rate as shown on the
model rating plate.
For safe operation of the water heater, the relief valve
must not be removed from its designated opening nor
plugged.
The Discharge Pipe:
• Should not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other
restrictions.
The temperature-pressure relief valve must be installed
directly into the fitting of the water heater designed for the
relief valve. Position the valve downward and provide
tubing so that any discharge will exit only within 6 inches
(153 mm) above a floor drain or external to the building,
see Figure 16. 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 (9.14 m), or use of more than
four elbows can cause restriction and reduce the discharge
capacity of the valve.
• Should not be plugged or blocked.
• Should be of material listed for hot water distribution.
• Should be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the
discharge pipe.
• Should terminate a maximum of six inches above a floor drain
or external to the building.
• Should not have any valve between the relief valve and tank.

Venting
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken
to ensure that (1) no one is in front of or around the outlet
of the temperature-pressure relief valve discharge line,
and (2) the water manually discharged will not cause any
bodily injury or property damage because the water may be
extremely hot.
If after manually operating the valve, it fails to completely
reset and continues to release water, immediately close
the cold water inlet to the water heater, follow the draining
instructions, and replace the temperature-pressure relief valve
with a new one.
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its use inhibits proper
drafting of the water heater.
Thermally Operated Vent Dampers: This gas-fired water
heater has a thermal efficiency at or above 80% which may
produce a relatively low flue gas temperature. Such temperatures
may not be high enough to properly open thermally operated
vent dampers. This would cause spillage of the flue gases and
may cause carbon monoxide poisoning.
Filling the Water Heater
Vent dampers must bear evidence of certification as complying
with the current edition of the American National Standard
ANSI Z21.66/CGA 6.14, cover electrically and mechanically
actuated vent dampers). Before installation of any vent damper,
consult your local Sears Service Center or the local gas supplier
for further information.
Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled with water.
Water must flow from the hot water faucet before turning “ON”
gas to the water heater.
To insure proper venting of this gas-fired water heater, the correct
vent pipe diameter must be utilized. Any additions or deletions
of other gas appliances on a common vent with this water heater
may adversely affect the operation of the water heater. Consult
your gas supplier if any such changes are planned.
To fill the water heater with water:
For proper venting in certain installations, a larger diameter vent
pipe may be necessary. Consult your local Sears Service Center
or gas supplier to aid you in determining the proper venting for
your water heater from the vent tables in the current edition of
the National Fuel Gas Code ANSI Z223.1/NFPA 54.
•
•
Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
Open the cold water supply valve to the water heater.
Periodically check the venting system for signs of obstruction or
deterioration and replace if needed.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
The combustion and ventilation air flow must not be obstructed.
•
•
To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run until
a constant flow is obtained. This will let air out of the water
heater and the piping.
The water heater with draft hood installed must be connected
to a chimney or listed vent pipe system, which terminates to the
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.
Check all water piping and connections for leaks. Repair as
needed.

•
For proper draft hood attachment, the draft hood legs may
be angled slightly inward.
Place the draft hood legs in the receiving holes on the top
of the water heater. The legs will snap in the holes to give a
tight fit. Secure the legs of the draft hood with the supplied
draft hood brackets.
•
Place the vent pipe over the draft hood. With the vent pipe
in position, drill a small hole through both the vent pipe and
draft hood. Secure them together with a sheet metal screw,
see Figure 18.
Chemical vapor corrosion of the flue and vent system may
occur if air for combustion contains certain chemical vapors.
Spray can propellants, cleaning solvents, refrigerator and air
conditioner refrigerants, swimming pool chemicals, calcium
and sodium chloride, waxes, bleach and process chemicals
are typical compounds which are potentially corrosive.
FIGURE 18.
Gas Piping
Obstructed or deteriorated vent systems may present serious
health risk or asphyxiation.
The vent pipe from the water heater must be no less than the
diameter of the draft hood outlet on the water heater and must
slope upward at least 1/4 inch per linear foot (21 mm per meter),
see Figure 19.
FIGURE 19.
All vent gases must be completely vented to the outdoors of the
structure (dwelling). Install only the draft hood provided with the
new water heater and no other draft hood.
Make sure the gas supplied is the same type listed on the
model rating plate. The inlet gas pressure must not exceed
14 inch water column (3.5kPa) for natural gas. The minimum inlet
gas pressure listed on the rating plate is for the purpose of input
adjustment. If the gas control valve is subjected to pressures
exceeding 1/2 pound per square inch (3.5kPa), the damage
to the gas control valve could result in a fire or explosion from
leaking gas.
Vent pipes must be secured at each joint with sheet metal screws.
There must be a minimum of 6 inches (153 mm) clearance
between single wall vent pipe and any combustible material.
Fill and seal any clearance between single wall vent pipe
and combustible material with mortar mix, cement, or other
noncombustible substance. For other than single wall, follow
vent pipe manufacturer’s clearance specifications. To insure a
tight fit of the vent pipe in a brick chimney, seal around the vent
pipe with mortar mix cement.
If the main gas line shut-off serving all gas appliances is used, also
turn “OFF” the gas at each appliance. Leave all gas appliances shut
“OFF” until the water heater installation is complete.
A gas line of sufficient size must be run to the water heater.
Consult the current edition of National Fuel Gas Code ANSI
Z223.1/NFPA 54 and your gas supplier concerning pipe size.
Failure to have required clearances between vent piping and
combustible material will result in a fire hazard.
Be sure vent pipe is properly connected to prevent escape of

Sediment Traps
The minimum inlet gas pressure shown on the rating plate is that
which will permit firing at the rated input.
Contaminants in the gas lines may cause improper operation of
the gas control valve that may result in fire or explosion. Before
attaching the gas line be sure that all gas pipe is clean on the
inside. To trap any dirt or foreign material in the gas supply line, a
drip leg (sometimes called a sediment trap) must be incorporated
in the piping. The drip leg must be readily accessible. Install in
accordance with the Gas Piping section. Refer to the current
edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
Water heaters covered in this manual have been tested and approved
for installation at elevations up to 7,700 feet (2,347 m) above sea
level. For installation above 7,700 feet (2,347 m), the water heater’s
Btu input should be reduced at the rate of 4 percent for each 1,000
feet (305 m) above sea level which requires replacement of the
burner orifice in accordance with the National Fuel Gas Code
ANSI Z223.1/NFPA 54. Contact your local gas supplier for further
information.
A sediment trap should be installed as close to the inlet of the
water heater as practical at the time of water heater installation. The
sediment trap should be either a tee fitting with a capped nipple in
the bottom outlet or other device recognized as an effective sediment
trap. If a tee fitting is used, it should be installed in conformance with
one of the methods of installation, shown in Figures 20 and 21.
Failure to replace the standard orifice with the proper high altitude
orifice when installed at elevations above 7,700 feet (2,347 m)
could result in improper and inefficient operation of the appliance,
producing carbon monoxide gas in excess of the safe limits. This
could result in serious injury or death. Contact your local gas supplier
for any specific changes that may be required in your area.

Never allow small children to use a hot water tap, or to draw their
own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
Temperature Regulation
Due to the nature of the typical gas water heater, the water
temperature in certain situations may vary up to 30°F (16.7° C)
higher or lower at the point of use such as, bathtubs, showers,
sink, etc.
NOTE: A water temperature range of 120°F-140°F (49°C-
60°C) is recommended by most residential dishwasher
manufacturers.
The thermostat of this water heater has been factory set at its
lowest position (PILOT LIGHTING). It is adjustable and must be
reset to the desired temperature setting to reduce the risk of scald
injury. The mark ( ) indicative of approximately 120°F (49°C)
is preferred starting point. Some states have a requirement for
a lower setting.
Turn the water temperature dial clockwise (

Should overheating occur or the gas supply fail to shut off, turn
off the manual gas control valve to the appliance.
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
will satisfy space heating, 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/mentally 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 addition 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
manufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, see Figures 22
and 23.

SERVICE AND ADJUSTMENT
Tank (Sediment) Cleaning
Burner Inspection
Sediment build-up on the tank bottom may create varying amount
of noise, and if left in the tank will cause permanent tank failure.
In some water areas, you may not be able to drain all sediment
deposits by simply draining the tank. In these cases Mag-Erad
(part no. 23600) can be used to help remove the sediment
deposits. This may be ordered from the Sears Service Center.
For ordering, refer to the Parts Order List section.
Flood damage to a water heater may not be readily visible
or immediately detectable. However, over a period of time
a flooded water heater will create dangerous conditions
which can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE. Contact a Sears Service Center to
replace a flooded water heater. Do not attempt to repair the
unit! It must be replaced!
At least once a year a visual inspection should be made of
the main burner and pilot burner, see Figure 24.
Vent System Inspection
At least once a year a visual inspection should be made of the
venting system. You should look for:
You should check for sooting. Soot is not normal and will
impair proper combustion.
•
Obstructions which could cause improper venting. The
combustion and ventilation air flow must not be obstructed.
Soot build-up indicates a problem that requires correction
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 causing death,
serious injury, or property damage.

Burner Cleaning
In the event your burner needs cleaning, following these
instructions:
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
If inspection of the burner shows that cleaning is required, turn
the gas control knob clockwise (
depressing slightly.
) to the “OFF” position,
Chemical vapor corrosion of the flue and vent system may occur
if air for combustion contains certain chemical vapors. Spray can
propellants, cleaning solvents, refrigerator and air conditioner
refrigerants, swimming pool chemicals, calcium and sodium
chloride, waxes, bleach and process chemicals are typical
compounds which are potentially corrosive.
NOTE: The knob cannot be turned from “PILOT” to “OFF”
unless knob is depressed slightly. DO NOT FORCE.
Loose deposits on or around the burner can be removed by
carefully using the hose of a vacuum cleaner inserted through
the access door of the water heater. If the burner needs to be
removed for additional cleaning, call the Sears Service Center
to remove and clean the burner and correct the problem that
required the burner to be cleaned.
If when inspecting the vent system you find sooting or
deterioration, something is wrong. Call the local gas supplier to
correct the problem and clean or replace the flue and venting
before resuming operation of the water heater.

Anode deterioration depends on water conductivity, not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/
or replaced more often than an anode rod that appears to be
intact. Replacement of a depleted anode rod can extend the
life of your water heater. Inspection should be conducted by
calling the Sears Service Center for an authorized contractor.
At a minimum, the anode(s) should be checked annually after
the warranty period.
Housekeeping
Vacuum around base of water heater for dust, dirt, and lint on
a regular basis.
INSTALLED IN SUITABLE AREA: To insure sufficient
ventilation and combustion air supply, proper clearances from
the water heater must be maintained. See Facts to Consider
About the Location section. Combustible materials such as
clothing, cleaning materials, or flammable liquids, etc. must not
be placed against or adjacent to the water heater because they
could catch on fire.
Temperature-Pressure Relief Valve Operation
The temperature-pressure relief valve must be manually operated
at least once a year.
When checking the temperature-pressure relief valve
operation, make sure that (1) no one is in front of or around
the outlet of the temperature-pressure relief valve discharge
line, and (2) that the water discharge will not cause any
property damage, as the water may be extremely hot, see
Figure 25.
Anode Rod Inspection
FIGURE 25.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions, and
replace the temperature-pressure relief valve with a new one.
The anode rod is used to protect the tank from corrosion.
Most hot water tanks are equipped with an anode rod. The
submerged rod deteriorates to protect the tank. Instead
of corroding the tank, water ions attack and eat away the
anode rod. This does not affect the water’s taste or color.
The rod must be maintained to keep the tank in operating
condition.
If the temperature-pressure relief valve on the appliance weeps or
discharges periodically, this may be due to thermal expansion. You
may have a check valve installed in the water line or a water meter
with a check valve. Consult the Sears Service Center for further
information. Do not plug the temperature-pressure relief valve.

TROUBLESHOOTING GUIDE
Start Up Conditions
Thermal Expansion
Water supply system may, because of such events as high line
pressure, frequent cut-offs, and the effects of water hammer have
installed devices such as pressure reducing valves, check valves,
back flow preventers, etc., to control these types of problems.
When these devices are not equipped with an internal by-pass,
and no other measures are taken, the devices cause the water
system to be closed. As water is heated, it expands (thermal
expansion) and closed systems do not allow for the expansion
of heated water.

On Tank
The water within the water heater tank expands as it is heated and
increases the pressure of the water system. If the relieving point
of water heater’s temperature-pressure relief valve is reached,
the valve will relieve the excess pressure. The temperature-
pressure relief valve is not intended for the constant relief
of thermal expansion. This is an unacceptable condition and
must be corrected.

NOTE: Expansion tanks are pre-charged with a 40 psi air
charge. If the inlet water pressure is higher than 40 psi, the
expansion tank’s air pressure must be adjusted to match
that pressure, but must not be higher than 80 psi.
It is recommended that any devices installed which could create
a closed system have a by-pass and/or the system have an
expansion tank or device to relieve the pressure built by thermal
expansion. Thermal expansion tanks are available from Sears
stores and through the Sears Service Centers. Contact the local
plumbing inspector, water supplier and/or the Sears Service
Center for assistance in controlling these situations, see Figure
26 and Figure 26 A.
Strange Sounds
Possible noises due to expansion and contraction of some metal
parts during periods of heat-up and cool-down do not represent
harmful or dangerous conditions.
Condensation causes sizzling and popping within the burner area
during heating and cooling periods and should be considered
normal. See Condensation section.
Draft Hood Operation
Check draft hood operation by performing a worst case
depressurization of the building. With all doors and windows
closed, and with all air handling equipment and exhaust fans
operating such as furnaces, clothes dryers, range hoods and
bathroom fans, a match flame should still be drawn into the draft
hood of the water heater with its burner firing. If the flame is not
drawn toward the draft hood, shut off water heater and make
necessary air supply changes to correct.
Condensation
Whenever the water heater is filled with cold water, some
condensate will form while the burner is on. A water heater may
appear to be leaking when in fact the water is condensation.
This usually happens when:
FIGURE 26.

•
•
A new water heater is filled with cold water for the first time.
•
•
little or no dissolved oxygen in the water.
a sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)
Burning gas produces water vapor in water heaters,
particularly high efficiency models where flue temperatures
are lower.
•
an excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
•
Large amounts of hot water are used in a short time and the
refill water in the tank is very cold.
Smelly water may be eliminated or reduced in some water
heater models by replacing the anode(s) with one of less active
material, and then chlorinating the water heater tank and all
hot water lines. Contact Sears Service for further information
concerning an Anode Replacement and this Chlorination
Treatment.
Moisture from the products of combustion condense on the cooler
tank surfaces and form drops of water which may fall onto the
burner or other hot surfaces to produce a “sizzling” or
“frying” noise.
Excessive condensation can cause pilot outage due to water
running down the flue tube onto the main burner and putting
out the pilot.
If the smelly water persists after the anode replacement and
chlorination treatment, we can only suggest that chlorination
or aeration of the water supply be considered to eliminate the
water problem.
Because of the suddenness and amount of water, condensation
water may be diagnosed as a “tank leak”. After the water in
the tank warms up (about 1-2 hours), the condition should
disappear.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.
“AIR” In Hot Water Faucets
Do not assume the water heater is leaking until there has been
enough time for the water in the tank to warm up.
An undersized water heater will cause more condensation.
The water heater must be sized properly to meet the family’s
demands for hot water including dishwashers, washing machines
and shower heads.
Excessive condensation may be noticed during the winter and
early spring months when incoming water temperatures are at
their lowest.
Good venting is essential for a gas fired water heater to operate
properly as well as to carry away products of combustion and
water vapor.
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,
located farthest away, be opened for several minutes 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 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 faucet at the time it is open.
Smoke Odor
It is not uncommon to experience a small amount of smoke and
odor during the initial start-up. This is due to burning off of oil
from metal parts, and will disappear in a short while.
Operational Conditions
Smelly Odor
In each water heater there is installed at least one anode rod
(see parts section) for corrosion protection of the tank. Certain
water conditions will cause a reaction between this rod and the
water. The most common complaint associated with the anode
rod is one of a “rotten egg smell”. This odor is derived
from hydrogen sulfide gas dissolved in the water. The smell is
the result of four factors which must all be present for the odor
to develop:
High Temperature Shut-Off System
This water heater is equipped with an automatic gas shutoff
system. This system shuts off the gas supply to the water heater
burner when high water temperatures are present. It is non-
resettable. If the high temperature shut off activates, the gas
control valve must be replaced. If this were to occur, turn “OFF”
the entire gas supply to the water heater. Contact the Sears
Service Center.

make sure the gas supply has been turned “OFF”, and never turn
the gas “ON” before the tank is completely full of water.
Operational Conditions (Continued)
Leakage Checkpoints
Never use this water heater unless it is completely filled with
water. To prevent damage to the tank, the tank must be filled
with water. Water must flow from the hot water faucet before
turning “ON” gas to the water heater, see Figure 27.
