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 shutoff valve
serving all gas appliances is used,
also shut “OFF” the gas at each
appliance. Leave all gas appliances
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.
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. Even though this water
heater is a flammable vapor ignition resistant water heater and
is designed to reduce the chances of flammable vapors being
ignited, gasoline and other flammable substances should never
be stored or used in the same vicinity or area containing a gas
water heater or other open flame or spark producing 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 drain pan should be
installed under the water heater. Drain pans are available at your
local Sears or hardware store. Such a drain pan must have a
minimum length and width of at least 2 inches (51 mm) greater than
the water heater dimensions and must be piped to an adequate
drain. The pan must not restrict combustion air flow.
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
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 drain pan piped
to a drain. Unanticipated damage can be reduced or prevented
by a leak detector or water shut-off device used in conjunction
with a piped drain pan. These devices are available from some
plumbing supply wholesalers and retailers, and detect and react
to leakage in various ways:
•
Sensors mounted in the drain pan that trigger an alarm or turn
off the incoming water to the water heater when leakage is
detected.
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 (76.2mm) 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.
•
•
Sensors mounted in the drain pan that turn off the water supply
to the entire home when water is detected in the 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.

FIGURE 9.
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 8 inches (203
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.
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 directly from outdoors (direct vent).
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.
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 NationalAppliance
Energy Conservation Act 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 Locating The New Water Heater 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.
Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.

•
•
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.
The confined space shall 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 shall communicate directly, or
by ducts, with the outdoors or spaces (crawl or attic) that freely
communicate with the outdoors.
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.
Combustion Air and Ventilation for
Appliances Located in Confined Spaces

•
When directly communicating with the outdoors, each opening
shall 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 11.
When communicating with the outdoors through vertical
ducts, each opening shall have a minimum free area of
1 square inch per 4,000 BTU per hour (5.5 cm2/kW) of
total input rating of all equipment in the enclosure. See
Figure 12.
CONFINED SPACE is a space whose volume is less than

A. ALL AIR FROM INSIDE BUILDINGS:
(See Figure 9 on page 10 and Figure 10 below)
The confined space shall 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 shall
be considered in making this determination. Each opening shall
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 shall 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 horizontal
ducts, each opening shall 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

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 14. 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 13A.
•
Louvers and Grilles: In calculating free area, consideration
shall be given to the blocking effect of louvers, grilles or
screens protecting openings. Screens used shall 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 shall be fixed in the open position
or interlocked with the equipment so that they are opened
automatically during equipment operation.
FIGURE 14.

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.

This water heater shall not be connected to any heating
systems or component(s) used with a non-potable water heating
appliance.
•
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 threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4” NPT threaded nipple. Using
flexible connectors, connect the cold water pipe to the cold
water inlet of the water heater.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
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.
Toxic chemicals, such as those used for boiler treatment shall
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, 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

This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
FIGURE 16.
The valve is certified by a nationally recognized testing laboratory
that maintains periodic inspection of production of listed
equipment as meeting the requirements for Relief Valves for Hot
Water Supply Systems,ANSI Z21.22 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 indicated in the above paragraph.
The Discharge Pipe:
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.
• Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge
pipe.
For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
• Shall terminate at an adequate drain.
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, or
at any distance below the structural floor, 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.
• Shall not have any valve between the relief valve and tank.
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 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.
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
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.
Filling the Water Heater
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.
the local gas supplier for further information.
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.
For replacement heater installations where pre-existing venting
is used, the venting must be inspected for obstructions and if
deterioration is present, it must be replaced.
To fill the water heater with water:
•
Close the water heater drain valve by inserting a flat head
screwdriver in the slot on the stem and turn to the right
(clockwise). The drain valve is on the lower front of the water
heater.
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.
•
•
Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
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.
Periodically check the venting system for signs of obstruction or
deterioration and replace if needed.
The combustion and ventilation air flow must not be
obstructed.
•
Check all water piping and connections for leaks. Repair as
needed.
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.
Venting
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.
•
•
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 to top with sheet metal screws. See
Figure 17.
Thermally Operated Vent Dampers: Gas-fired water heaters
having thermal efficiency in excess of 80% 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.
•
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.
Vent dampers must bear evidence of certification as complying
with the current edition of the American National Standard
Obstructed or deteriorated vent systems may present serious
health risk or asphyxiation.

Be sure vent pipe is properly connected to prevent escape of
dangerous flue gases which could cause deadly asphyxiation.
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 17.
Gas Piping
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 18.
FIGURE 18.
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 and propane gas (L.P.)
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 shutoff 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.
There must be:
•
A readily accessible manual shut off valve in the gas supply
line serving the water heater.
•
A drip leg (sediment trap) ahead of the gas control valve to
help prevent dirt and foreign materials from entering the gas
control valve.
•
A flexible gas connector or a ground joint union between the
shut off valve and control valve to permit servicing of the
unit.
Be sure to check all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a match or open
flame. Rinse off soapy solution and wipe dry.
Failure to have required clearances between vent piping and

Sediment Traps
Water heaters covered in this manual have been tested and
approved for installation at elevations up to 2,000 feet (610
m) above sea level. For installation above 2,000 feet (610 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.
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.
Failure to replace the standard orifice with the proper high
altitude orifice when installed at elevations above 2,000 feet
(610 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.
Asediment trap shall be installed as close to the inlet of the water
heater as practical at the time of water heater installation. The
sediment trap shall 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 shall be installed in
conformance with one of the methods of installation, shown in
Figures 19 and 20.

Temperature Regulation
The thermostat of this water heater has been factory set at its
lowest position. It is adjustable and must be reset to the desired
temperature setting for energy efficient operation at the minimum
water temperature setting that meets your hot water needs. To
reduce the risk of scald injury, 120°F (49°C) is preferred starting
point. Some states have a requirement for a lower setting.
Due to the nature of the typical gas water heater, the water
temperature in certain situations may vary up to 30F° (16.7 C°)
higher or lower at the point of use such as, bathtubs, showers,
sink, etc.
Align the index bar on the thermostat with the desired water

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 21 and 22.

SERVICE AND ADJUSTMENT
Tank (Sediment) Cleaning
Burner Inspection
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!
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.
At least once a year a visual inspection should be made of the
main burner. See Figure 23.

ARRESTOR. CLEAN IF LINT ACCUMULATIONS ARE
NOTICED.
5. Refer to “Gas Piping” section and disconnect the ground
joint union in the gas piping. Disconnect the remaining
pipe from the gas control valve/thermostat.
INSTALLED IN SUITABLEAREA: 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.
6. To remove the gas valve, thread a correctly sized pipe into
the inlet and use it to turn the gas valve (counterclockwise.)
Do not use pipe wrench or equivalent to grip body.
Damage may result, causing leaks. Do not insert any sharp
objects into the inlet or outlet connections. Damage to the
gas valve may result.
Anode Rod Inspection
Replacing the Gas Valve:
To replace the gas control valve/thermostat, reassemble
in reverse order. When replacing the gas valve, thread a
correctly sized pipe into the inlet and use it to turn the gas
valve (clockwise.) DO NOT OVER TIGHTEN, damage may
result.
•
Be sure to use approved Teflon® tape or pipe joint
compound on the gas piping connections and fitting on
the back of the gas control valve that screws into tank.
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.
•
•
Be sure to remove the pilot ferrule nut from the new gas
control valve/thermostat.
Turn the gas supply on and check for leaks. Test all
connections by brushing on an approved noncorrosive
leak-detection solution. Bubbles will show a leak. Correct
any leak found.
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.
•
•
Be sure tank is completely filled with water before lighting
and activating the water heater. Follow the “Operating
Instructions”

Start Up Conditions
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.
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.
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.
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 34.

a concentration of sulfate in the supply water.
little or no dissolved oxygen in the water.
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:
a sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)
•
an excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
•
•
A new water heater is filled with cold water for the first time.
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 Kit #9001453 and this Chlorination
Treatment. Anode replacement and chlorination of the tank are
not covered by the water heater’s limited warranty.
Burning gas produces water vapor In water heaters,
particularly high efficiency models where flue temperatures
are lower.
•
Large amounts of hot water are used in a short time and the
refill water in the tank is very cold.
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.
If the smelly water persists after the anode replacement and
chlorination treatment, it may be necessary to chlorinate or aerate
your water supply to eliminate the problem.
Do not remove the anode leaving the tank unprotected. By
doing so, all warranty on the water heater tank is voided.
Excessive condensation can cause pilot outage due to water
running down the flue tube onto the main burner and putting
out the pilot.
“AIR” In Hot Water Faucets
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 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.
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.
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.
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
High Temperature Shut Off System
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:
This water heater is equipped with an automatic gas shutoff
system. This system works when high water temperatures
are present. The high temperature shutoff is built into the gas
control valve. It is non-resettable. If the high temperature shutoff
activates, the gas control valve must be replaced. Turn “OFF”
the entire gas supply to the water heater and contact your gas
supplier.
