This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident.
The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the
following checklist and make any required installation upgrades or changes.
Questions? Contact Sears at 1-800-4-MY-HOME (1-800-469-4663).
Installation Checklist
Water Heater Location
Water heater location is important and
performance. Please check the following:
[]
can affect system
Installation area free of corrosive elements and flammable
materials.
[] Centrally located with the water piping system (For new
installations). Located as close to the gas piping and vent
pipe system as possible.
[] Located indoors and in a vertical position. Protected from
freezing temperatures.
[] Proper clearances from combustible surfaces
maintained and not installed directly on a carpeted floor.
[] Provisions made to protect the area from water damage.
Metal drain pan installed and piped to an adequate drain.
[] Sufficient room to service the water heater. See Clearances
and Accessibility section of this manual.
[] Water heater not located near an air moving device.
[] Is the installed environment dirty (excessive amounts of
lint, dirt, dust, etc.)? If so, the base-ring filter located on
the bottom of the water heater wilt need to be cleaned
periodically. Refer to the "Maintenance of your Water
Heater" section of this manual for information on cleaning
the base-ring filter.
[]
[]
Combustion Air Supply and Ventilation
Check for sufficient combustion air supply. Insufficient air for
the combustion of gas wilt result in the flame becoming "lazy",
thereby allowing heat to build up in the combustion chamber.
This excessive heat wilt cause a thermal switch on the door
assembly to trip. Is the water heater installed in a closet or other
small, enclosed space? If so:
Are there openings for make-up air to enter and exit the
room/area?
Are the openings of sufficient size? Remember, if there
are other gas-fired or air-consuming appliances in the
same room, you need more make-up air. Refer to the
"Installation Instructions" and "Combustion Air Supply and
Ventilation" sections for specific requirements.
[] Make sure that fresh air is not taken from areas that contain
negative pressure producing devices such as exhaust fans,
dryers, fireplaces, etc.
[] Is there a furnace/air handler in the same room space as
the water heater? If so, has a return air duct system been
attached that exits the room? If so, check for leaks on the
air duct system. If no air duct system is present, correct
immediately by contacting a local Heating, Ventilation, Air-
Conditioning & Refrigeration (HVAC-R) authorized service
provider.
[] Use a fresh air supply that is free of corrosive elements and
flammable vapors.
[] Fresh airopenings must be sized correctly with consideration
given to the blocking effect of louvers and grilles.
Vent Pipe System
Check for proper drafting at the water heater draft hood. Refer
to the "Checking the Draft" section of this manual for the test
procedure. If the procedure shows insufficient draft is present,
please check the following:
[]
[]
[]
[]
[]
[]
Draft hood properly installed.
Vent connectors securely fastened with screws and
supported properly to maintain six inch clearance.
Vent connector made of approved material and sized
correctly.
Vent pipe system installed according to all local and state
codes or, in the absence of local and state codes, the
"National Fuel Gas Code", ANSI Z223.1 (NFPA 54)-current
edition. Manufactured home manufacturers must conform
with the "Manufactured Home Construction and Safety
Standard, Title 24 CFR, Part 3280."
Flue baffle properly positioned in the flue tube.
Check the vent system for restrictions/obstructions and
check the vent termination height. Refer to the "Combustion
Air Supply and Ventilation" section of this water heater
manual for specific requirements.
[] Recheck for sufficient combustion air supply.
Water System Piping
[] Temperature and pressure relief valve properly installed
with a discharge line run to an adequate drain and protected
from freezing.
[] All piping properly installed and free of leaks.
[] Heater completely filled with water.
[] Closed system pressure build-up devices installed.
[] Mixing valve (when applicable) installed per manufacturer's
instructions (See "Water Temperature Regulation" section).
Gas Supply and Piping
[]
[]
[]
[]
[]
Gas type is the same as that listed on the water heater rating
plate unless the water heater has been properly converted.
Refer to the "Gas Conversion" section of this manual.
Gas line equipped with shut-off valve, union, and drip leg.
Use pipe joint compound or teflon tape marked as being
resistant to the action of petroleum [Propane (L.R)] gases.
Adequate pipe size and approved pipe material.

the fire department from a neighbor's home. Do not attempt to
clean the spill until all ignition sources have been extinguished.
The FVIR System is designed to reduce the risk of flammable
vapor-related fires. The patented system protects your family by
trapping the burning vapors within the water heater combustion
chamber through the special flame-arrestor. The burning vapors
literally "burn themselves out" without escaping back into the
room. In the event of a flammable vapor incident, the FVIR
System disables the water heater by shutting off the gas supply
to the water heater's burner and pilot, preventing re-ignition
of any remaining flammable vapors in the area. This will not
prevent a possible fire/explosion if the igniter is depressed
and flammable vapors have accumulated in the combustion
chamber with the pilot light off. If you suspect a flammable
vapor incident has occurred, do not use this appliance. Do not
attempt to light this appliance, or depress the igniter button
if you suspect flammable vapors have accumulated inside or
outside the appliance. Immediately call a qualified technician to
inspect the appliance. Water heaters subjected to a flammable
vapors incident will show a discoloration on the flame-arrestor
and require replacement of the entire water heater.

Water heater life depends upon water quality, water usage,
water temperature 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:
• Sensors mounted in the metal drain pan that trigger an
alarm or turn off the incoming water to the water heater
when water 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 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 wilt turn off the gas supply to a gas water
heater while at the same time shutting off its water supply.
Securing Water Heater to Floor and Wall
The water heater must be secured to the floor and to the wall
of the enclosure as described below. See also "Enclosure
Installation."
After properly locating the water heater, fasten it to the
floor with the brackets and screws that were provided
(Figure 9). Simply pre-dritt each screw location in the
metal drain pan and water heater jacket with a 118"drill bit.
Because of installation variances, these brackets can be
located at any points around the circumference of the jacket.
However, they should be spaced apart at equal distances.
2,
CAUTION: When making pilot holes in the water
heater itself, ensure that you drill only the outer jacket.
Also, to prevent leaks in the metal drain pan, seal each drill
location with a heavy bead of silicone sealant.
Secure the top of the water heater with the provided bracket
and screws or install other acceptable means of support
(e.g., support strap).
FIGURE 9.
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 toss encountered with storage tank heaters. Your
Kenmore water heater meets or exceeds the National Appliance
Energy Conservation Act standards with respect to insulation
and standby loss requirements, making an insulation blanket
unnecessary.

Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
_1_ 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.
• 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.

Clearances and Accessibility
NOTE: Minimum clearances from combustible surfaces are
stated on the label adjacent to the gas control valve/thermostat
of the water heater. The water heater is certified for installation
on a combustible floor.
• IMPORTANT: If installing over carpeting, the carpeting
must be protected by a metal or wood panel beneath the
water heater. The protective panel must extend beyond the
full width and depth of the water heater by at least three
inches (76.2mm) in any direction; or if in an alcove or closet
installation, the entire floor must be covered by the panel.

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. To fill the water heater with water:
• 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.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
To ensure 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.
Check all water piping and connections for leaks. Repair as
needed.
Property Damage Hazard
• Avoid water heater damage.
• Fill tank with water before operating.
FIGURE 10.

INSTALL THE CONVERSION MANIFOLD/BURNER
ASSEMBLY
1. Check the door gasket for damage or imbedded debris prior
to installation.
2. Inspect the view port for damage and replace as required.
3. Insert the conversion manifold/burner assembly into the
burner compartment, making sure that the tip of the manifold
tube engages the slot of the bracket inside the combustion
chamber. NOTE: For 30 gallon models, the LP manifold/
burner assembly is identified by a yellow dot (label) on the
packaging. For 40 gallon models, the LP manifold/burner
assembly is identified by a green dot on the packaging.
4. Inspect the door gasket and make sure there is no fiberglass
insulation between the gasket and the combustion chamber.
5. Replace the two screws that secure the manifold/burner
assembly door to the combustion chamber and tighten
securely. Once the manifold/burner assembly door istightened,
visually inspect the door gasket between the manifotd/bumer
assembly door and the combustion chamber for spaces or
gaps that would prevent a seal. IMPORTANT: Do not operate
the water heater if the door gasket does not create a seal
between the manifold door and the combustion chamber.
6. During the following procedure, do not cross-thread or apply
any thread sealant to any of the fittings listed below. See
Figure 11. First, reconnect the manifold tubing to the gas
control valve/thermostat. Second, locate the provided ferrule
nut and install it in the gas control valve/thermostat at the
pilot location, hand tight only. Third, insert the pilot tube into
the ferrule nut until it bottoms out, then hold the tube in this
position. Tighten the ferrule nut with a wrench until the crimp
connection seals to the pilot tube. Continue to tighten until the
nut is tight in the gas control valve/thermostat. Finally, start
the thermocouple nut and turn it all the way in by hand. An
additional quarter turn with a 3/8" open-end wrench wilt then
be sufficient to seat the lockwasher. When you are finished,
connect the two wire leads that go to the thermal switch.
Finally, reconnect the igniter wire.
7. Turn gas supply on and refer to the Lighting Instructions.
8. With the burner tit, check the gas control valve/thermostat
supply line, manifold component block, manifold tube, and
pilot tube connections for leaks. Check for leaks by brushing
on an approved non-corrosive leak detection solution.

Gas Requirements
IMPORTANT: Read the rating plate to be sure the water heater
is made for the type of gas you wilt be using in your home. This
information wilt be found on the rating plate located near the gas
control valve/thermostat. If the information does not agree with
the type of gas available, do not install or light. Call your dealer.
NOTE: If your water heater has been converted, the rating plate
may list a different type of gas than what you wilt be using in your
home. Also, an odorant is added by the gas supplier to the
gas used by this water heater. This odorant may fade over an
extended period of time. Do not depend upon this odorant as an
indication of leaking gas.
Gas Piping
The gas piping must be installed according to all local and
state codes or, in the absence of local and state codes, the
"National Fuel Gas Code", ANSI Z223.1 (NFPA 54)-current
edition. Manufactured home manufacturers must conform with
"The Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280".
Tables 1and 2 on the following page provide a sizing reference for
commonly used gas pipe materials. Consult the "National Fuel Gas
Code" for the recommended gas pipe size of other materials.
NOTE: Use pipe joint compound or teflon tape marked as being
resistant to the action of petroleum [Propane (L.R)] gases.

• For more information, contact your gas supplier.
• If a gas leak is detected, follow the "What to do if you
smell gas" instructions on the cover of this manual.
IMPORTANT:The gas supply pressure must not exceed the maximum
supply pressure as stated on the water heater's rating plate. The
minimum supply pressure is for the purpose of input adjustment.
Gas Pressure Testing
IMPORTANT: This water heater and its gas connection must be
leak tested before placing the appliance in operation.
• If the code requires the gas lines to be tested at a pressure
exceeding 14" W.C., the water heater and its manual shut-off
valve must be disconnected from the gas supply piping system
and the line capped.
• If the gas lines are to be tested ata pressure less than 14"W.C.,
the water heater must be isolated from the gas supply piping
system by closing its manual shut-off valve.
U.L. recognized fuel gas and carbon monoxide (CO) detectors are
recommended in all applications and should be installed using the
manufacturer's instructions and local codes, rules and regulations.
NOTE: Air may be present in the gas lines and could prevent the
pilot from lighting on initial start-up. The gas lines should be purged
of air by a qualified technician after installation of the gas piping
system. While purging the gas piping system of air, ensure that
the fuel is not spilled in the area of the water heater installation,
or any source of ignition. If the fuel is spilled while purging the
piping system of air follow the "WHAT TO DO IF YOU SMELL
GAS" instructions on the cover of this manual.

LP Gas Only
Liquefied petroleum gas is over 50% heavier than air and in the
occurrence of a leak in the system, the gas wilt settle at floor level.
Basements, crawl spaces, skirted areas under mobile homes
(even when ventilated), closets and areas below ground level will
serve as pockets for the accumulation of gas. Before lighting an
L.R gas water heater, smell all around the appliance at floor level.
If you smell gas, follow the instructions as given inthe warning on
the front page.
When your L.R tank runs out of fuel, turn off the gas at all gas
appliances including pilot lights. After the tank is refilled, all
appliances must be re-lit according to their manufacturer's
instructions.

Carbon Monoxide Warning
The vent system must be installed according to all
local and state codes or, in the absence of local and
state codes, the "National Fuel Gas Code", ANSI
Z223.1 (NFPA 54)-current edition. Manufactured home
manufacturers must comply with the "Manufactured
Home Construction and Safety Standard, Title 24 CFR,
Part 3280."
Failure to do so can result in death, explosion, or
carbon monoxide poisoning.
IMPORTANT: Air for combustion and ventilation must not come
from a corrosive atmosphere. Any failure due to corrosive elements
in the atmosphere is excluded from warranty coverage.
The following types of installation (not limited to the following)
wilt require outdoor air for combustion due to chemical exposure
and may reduce but not eliminate the presence of corrosive
chemicals in the air:
• beauty shops
• photo processing tabs
• buildings with indoor pools
• water heaters installed in laundry, hobby, or craft rooms
• water heaters installed near chemical storage areas
Combustion air must befree ofacid-forming chemicals such assulfur,
fluorine, and chlorine. These elements are found in aerosol sprays,
detergents, bleaches, cleaning solvents, air fresheners, paint, and
vamish removers, refrigerants, and many other commercial and
household products. When bumed, vapors from these products
form highly corrosive acid compounds. These products should not
be stored or used near the water heater or air inlet.
Vent Pipe System
This water heater uses a non-direct, single-pipe vent system
to remove exhaust gases created by the burning of fossil
fuels. Air for combustion is taken from the immediate water
heater location or is ducted in from the outside (see "Enclosure
Installation").
This water heater must be properly vented for the removal of
exhaust gases to the outside atmosphere. Correct installation
of the vent pipe system is mandatory for the proper and efficient
operation of this water heater and is an important factor in the
life of the unit.
The vent pipe must be installed according to all local and state
codes or, in the absence of local and state codes, the "National
Fuel Gas Code", ANSI Z223.1 (NFPA 54)-current edition.
Manufactured home manufacturers must conform with "The
Manufactured Home Construction and Safety Standard, Title
24 CFR, Part 3280." The vent pipe installation must not be
obstructed so as to prevent the removal of exhaust gases to the
outside atmosphere.
IMPORTANT: The use of vent dampers is not recommended
by the manufacturer of this water heater. Although some vent
dampers are certified by CSA International, this certification
applies to the vent damper device only and does not mean they
are certified for use on this water heater.
U.L. recognized fuel gas and carbon monoxide (CO) detectors are
recommended in all applications and should be installed using the
manufacturer's instructions and local codes, rules, or regulations.
IMPORTANT: If you tack the necessary skills required to
properly install this venting system, you should not proceed, but
get help from a qualified technician.

Enclosure Installation
Air for combustion and ventilation must not be supplied from
the occupied spaces of the manufactured (mobile) home.
IMPORTANT: The openings that provide outside air to your
water heater must have a minimum free area of 100 square
inches. Suggested covering for the air openings is a 1/4 inch
wire mesh screen or louvers. (Floor openings should use 1/4
inch wire mesh screen.) Also, ensure that your installation
complies with all applicable code requirements.
The following methods may be used to provide sufficient
combustion and ventilation air to the water heater when it is
installed in the enclosure.
Method I (Figure 15)
Provide two (2) air openings in the door of the enclosure. The
combined area of these openings must be a minimum of 100
square inches. The top edge of the upper air opening must
be within 12 inches from the top of the enclosure. The bottom
edge of the lower air opening must be within 6 to 12 inches
from the floor of the enclosure. Suggested covering for the air
openings is a 1/4 inch wire mesh screen or louvers.
Method II (Figure 16)
Provide one (1) air opening in the door. The upper edge must
be located within 12 inches from the top of the enclosure.
Provide a second opening in the floor. The combined area
of these openings must be a minimum of 100 square inches.
Suggested covering for the air openings is a 1/4 inch wire mesh
screen or louvers. (Use 1/4 inch wire mesh screen for the floor
opening.)
Method III (Figure 17)
Provide two (2) air openings in the door of the enclosure. The
top edge of the upper air opening must be within 12 inches
from the top of the enclosure. The bottom edge of the lower
air opening must be within 6 to 12 inches from the floor of the
enclosure. Provide a third opening in the floor. The combined
area of these openings must be a minimum of 100 square
inches. Suggested covering for the air openings is a 1/4 inch
wire mesh screen or louvers. (Use 1/4 inch wire mesh screen
for the floor opening.)
IMPORTANT:
• When using method II or III, ensure that the drain pan does
not cover the air intake opening in the floor.
• A discharge line must be installed as described in the
"Temperature and Pressure Relief Valve" section.
• Do not obstruct the combustion and ventilation air openings.
• Do not use the enclosure as a storage area.
• Secure the water heater as described in "Securing Water
Heater to Floor and Wall."
• The combustion and ventilation air openings must have a
combined area of at least 100 square inches. This minimum
combined area is based on a 40,000 BTU/hr input and a
minimum air requirement of 50 cubic feet per 1,000 BTU/hr.
A water heater with a 40,000 BTU/hr input rating (as shown
on the data plate) will require 2,000 cubic feet of air per hour
to operate properly.

Piping Installation
Piping, fittings, and valves should be installed according to the
installation drawing (Figure 18). If the indoor installation area
is subject to freezing temperatures, the water piping must be
protected by insulation.
The water supply pressure should not exceed 80 psi. If this
occurs, a pressure reducing valve with a bypass may need to
be installed in the cold water inlet line. This should be placed
on the supply to the entire house in order to maintain equal hot
and cold water pressures.
IMPORTANT: Heat cannot be applied to the water fittings on
the heater as they may contain nonmetallic parts. If solder
connections are used, solder the pipe to the adapter before
attaching the adapter to the hot and cold water fittings.
IMPORTANT: Always use a good grade of joint compound and
be certain that all fittings are drawn up tight.
1. Install the water piping and fittings as shown in Figure 18.
Connect the cold water supply (3/4" NPT) to the cold water
inlet fitting. Connect the hot water supply (3/4" NPT) to the
hot water outlet fitting.
IMPORTANT: Some models may contain energy saving heat
traps to prevent the circulation of hot water within the pipes. Do
not remove the inserts within the heat traps.

The installation of unions in both the hot and cold water
supply lines is recommended for ease of removing the
water heater for service or replacement.
The manufacturer of this water heater recommends
installing a mixing valve or an anti-scald device in the
domestic hot water line as shown in Figure 19. These
valves reduce the point-of-use temperature of the water
by mixing cold and hot water and are readily available for
use.
If installing the water heater in a closed water system,
install an expansion tank in the cold water line as specified
under "Closed System/Thermal Expansion."
Install a shut-off valve in the cold water inlet line. It
should be located close to the water heater and be easily
accessible. Know the location of this valve and how to shut
off the water to the heater.
A temperature and pressure relief valve must be installed
in the opening marked "Temperature and Pressure
(T & P) Relief Valve" on the water heater. A discharge line
must be added to the opening of the T&P Relief Valve.
Follow the instructions under "Temperature and Pressure
Relief Valve."
After piping has been properly connected to the water
heater, remove the aerator at the nearest hot water faucet.
Open the hot water faucet and allow the tank to completely
fill with water. To purge the lines of any excess air, keep
the hot water faucet open for 3 minutes after a constant
flow of water is obtained. Close the faucet and check all
connections for leaks.

Please note the following:
• The system should be installed only with piping that is
suitable for potable (drinkable) water such as copper, CPVC,
or polybutytene. This water heater must not be installed
using iron piping or PVC water piping.
• Use only pumps, valves, or fittings that are compatible with
potable water.
• It is recommend that only full flow ball or gate valves are used
in water piping installations. The use of valves that may cause
excessive restriction to water flow is not recommended.
• Use only 95/5 tin-antimony or other equivalent solder. Any
lead based solder must not be used.
• Piping that has been treated with chromates, boiler seal, or
other chemicals must not be used.
• Chemicals that may contaminate the potable water supply
must not be added to the piping system.

Water Piping Pressure Test Temperature and Pressure Relief Valve
If the water piping system is to be air pressure tested, the
water heater must be disconnected from the water piping
system. Failure to disconnect the water heater during air
pressure testing of the water piping system could result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
This section is only for the manufacturer installing the water
heater when the installation is to comply with H.UD. Standards.
When testing the water ways, H.U.D. standards state: "Water
distribution system. All water piping in the water distribution
system shall be subjected to a pressure test. The test shall be
made by subjecting the system to air or water at 100 psi for 15
minutes without toss of pressure. When air pressure is used,
the water heater shall not be connected during the test."

• Do not install without adequate drainage,
As water is heated, it expands (thermal expansion). In a closed
system, the volume of water will grow. As the volume of water grows,
there will be a corresponding increase in water pressure due to
thermal expansion. Thermal expansion can cause premature tank
failure (leakage). This type of failure is not covered under the limited
warranty. Thermal expansion can also cause intermittent temperature-
pressure relief valve operation: water discharged from the valve due
to excessive pressure build up. The temperature-pressure relief valve
is not intended for the constant relief of thermal expansion. This
condition is not covered under the limited warranty.
A properly sized thermal expansion tank should be installed
on all closed systems to control the harmful effects of 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.

For protection against excessive pressures and temperatures,
a temperature and pressure relief valve must be installed in the
opening marked "T & P RELIEF VALVE." (See Figure 21). This
valve must be design certified by a nationally recognized testing
laboratory that maintains periodic inspection of the production
of listed equipment or materials as meeting the requirements
for Relief Valves for Hot Water Supply Systems, ANSI Z21.22.
The function of the temperature and pressure relief valve is to
discharge water in large quantities in the event of excessive
temperature or pressure developing in the water heater. The
valve's relief pressure must not exceed the working pressure of
the water heater as stated on the rating plate.
IMPORTANT: Only a new temperature and pressure relief valve
should be used with your water heater. Do not use an old or
existing valve as it may be damaged or not adequate for the
working pressure of the new water heater. Do not place any
valve between the relief valve and the tank.
The Temperature & Pressure Relief Valve:
• Must not be in contact with any electrical part.
• Must be connected to an adequate discharge line.
• Must not be rated higher than the working pressure shown
on the rating plate of the water heater.
The Discharge Line:
• Must not be smaller than the pipe size of the relief valve or
have any reducing coupling installed in the discharge line.
• Must not be capped, blocked, plugged or contain any valve
between the relief valve and the end of the discharge line.
• Must pass through the structural floor and terminate
external to the building. In cold climates, it is recommended
that the discharge pipe be terminated at an adequate drain
inside the building.
• Must be capable of withstanding 250°F (121°C)without distortion.
• Must be installed to allow complete drainage of both the
valve and discharge line.
T&P Relief Valve and Pipe Insulation (Some Models)
1. Locate the temperature and pressure relief valve on the water
heater (also known as a T&P relief valve). See Figure 22.
2. Locate the slit running the length of the T&P relief valve
insulation.
3. Spread the slit open and fit the insulation over the T&P relief
valve. See Figure 22. Apply gentle pressure to the insulation
to ensure that it is fully seated on the T&P Relief Valve. Once
seated, secure the insulation with duct tape, electrical tape,
or equivalent. IMPORTANT: The insulation and tape must not
block the discharge opening or hinder access to the manual
relief lever (Figure 22). Ensure a discharge pipe is installed into
the T&P valve discharge opening per the instructions in this
manual.
4. Locate the hot water (outlet) & cold water (inlet) pipes to the
water heater.
5. Locate the slit running the length of a section of pipe
insulation.
6. Spread the slit open and slip the insulation over the cold water
(inlet) pipe. Apply gentle pressure along the length of the
insulation to ensure that it is fully seated around the pipe. Also,
ensure that the base of the insulation is flush with the water
heater. Once seated, secure the insulation with duct tape,
electrical tape, or equivalent.
7. Repeat steps 5 and 6 for the hot water (outlet) pipe.
8. Add additional sections of pipe insulation as needed.

Checking the Draft
Burn Hazard
Do not touch vent.
Doing so can result in burns.
After successfully lighting the water heater, allow the unit to operate
for 15 minutes and check the draft hood relief opening for proper
draft (Figure 23). Make sure all other appliances in the area are
operating and all doors are closed when performing the draft test.
Pass a match flame around the relief opening of the draft hood. A
steady flame drawn into the opening indicates proper draft.

FIGURE 23.
If the flame flutters or is blown out, combustion products are
escaping from the relief opening. If this occurs, do not operate the
water heater until proper adjustments or repairs are made to the
vent pipe system and/or air supply requirements.
Burner Flames
Inspect the burner flames through the viewport and compare them
to the drawing in Figure 24. A properly operating burner should
produce a soft blue flame. Blue tips with yellow inner cones are
satisfactory. The tips of the flame may have a slight yellow tint.
The flame should not be all yellow or have a sharp blue-orange
color. Contaminated air may cause an orange colored flame.
Contact a qualified technician if the flame is not satisfactory.
FIGURE 24.
Emergency Shut Down
IMPORTANT: Should overheating occur or the gas supply fails
to shut off, turn off the water heater's manual gas control valve
and call a qualified technician.
Water Temperature Regulation
IF.'WmT_.l_[d :1;|
Water temperature over 125°F (52°C)
can cause servere burns instantly
resulting in severe injury or death.
Children, the elderly, and the
physically or mentally disabled are at
highest risk for scald injury.
Feel water before bathing or
showering.
Temperature limiting valves are
available.
Read instruction manual for safe
temperature setting.
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.
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. See Figure 19. Follow
manufacturer's instructions for installation of the valves. Before
changing the factory setting on the thermostat, see Figure 25.
Using the lowest hot water temperature that meets your needs
will also provide the most energy efficient operation of the water
heater.
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.
NOTE: Awater temperature range of 120°F-140°F (49°C-60°C)
is recommended by most dishwasher manufacturers.
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 to reduce the risk of scald injury. The •
mark is indicative of approximately 120°F (49°C) and is the
25
preferred starting point. See Figure 25. Some states have a
requirement for a lower setting.
Turn the water temperature dial clockwise ( t'_ ) to decrease
the temperature, or counterclockwise ( _ ) to increase the
temperature.
Should overheating occur or the gas supply fail to shut off, turn
off the manual gas control valve to the appliance.
During tow demand periods when hot water is not being used,
a lower thermostat setting will reduce energy losses and may
satisfy your normal hot water needs.
If hot water use is expected to be more than normal, a higher
thermostat setting may be required to meet the increased
demand.
When leaving your home for extended periods
(vacations, etc.) turn the temperature dial to its lowest
setting. This wilt maintain the water at tow temperatures with
minimum energy losses and prevent the tank from freezing
during cold weather.

Vent System Inspection
Ca_on Monoxide and Fire Hazard
* Flue gases may escape if vent pipe
is not connected,
* Be alert for obstructed, sooted or
deteriorated vent system to avoid
serious injury or death.
• Do not store corrosive chemicals
in vicinity of water heater.
• ChemicaJ corrosion of flue and vent
system can cause serious injury or
death
Breathing carbon monoxide can cause brain damage or
death Always read and understand instruction manual
You should check for sooting. Soot is not normal and will impair
proper combustion.
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.
FIGURE 26.
Burner Cleaning
Fire or Explosion Hazard
At least once a year, a visual inspection should be made of the
venting system. You should look for:
• Obstructions which could cause improper venting. The
combustion and ventilation air flow must not be obstructed.
• Damage or deterioration which could cause improper venting
or leakage of combustion products.
• Rusted flakes around top of water heater.
Be sure the vent piping is properly connected to prevent escape of
dangerous flue gasses which could cause deadly asphyxiation.
Obstructions and deteriorated vent systems may present serious
health risk or 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.
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.
Failure to properly reseal the combustion chamber will
disable the flammable vapor ignition resistance feature
of this water heater, which could result in death or serious
injury. Contact your local Sears Service Center
for assistance.
Read instruction manual before
installing, using or servicing
water heater.
If inspection of the burner shows that cleaning is required, turn the
gas control knob clockwise ( t'_ ) to the "OFF" position, depressing
slightly.
NOTE: The knob cannot be turned from PILOT to OFF unless
knob is depressed slightly. DO NOT FORCE.
The burner needs to be removed for cleaning. Call the Sears Service
Center to remove and clean the burner and correct the problem that
required the burner to be cleaned.
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! tt must be replaced!
At least once a year, a visual inspection should be made of the main
burner and pilot burner. See Figure 26.
27
Housekeeping
Vacuum around base of water heater for dust, dirt, and lint on
a regular basis.
Fire and Explosion Hazard
Do not obstruct combustion air
openings at the bottom of the
water heater.
Do not use or store flammable
vapor products such as gasoline,
solvents or adhesives in the
same room or area near water
heater or other appliance.
At least annually, check the
base-ring filter and flame arrester
for any dust, lint, or debris that
may have accumulated. Clean
as necessary.
Can cause serious injury or death.
AT LEAST ANNUALLY, A VISUAL INSPECTION SHOULD BE
MADE OF THE BASE-RING FILTER AND FLAME ARRESTER.
CLEAN IF LINT ACCUMULATIONS ARE NOTICED.
INSTALLED IN SUITABLEAREA: To ensure sufficient ventilation
and combustion air supply, proper clearances from the water
heater must be maintained. See "Installation Instructions."
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.
Anode Rod Inspection
Property Damage Hazard
• Avoid water heater damage.
• Inspection and replacement of anode rod required.
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.
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.

It is recommended that the tank be drained and flushed
every 6 months to remove sediment which may build up during
operation. The water heater should be drained if being shut
down during freezing temperatures. To drain the tank, perform
the following steps:
1. Turn off the gas to the water heater at the manual gas shut-
off valve.
2. Open a nearby hot water faucet until the water is no longer
hot.
3. Close the cold water inlet valve.
4. Connect a hose to the drain valve and terminate it to an
adequate drain or external to the building.
5. Open the water heater drain valve and allow all of the water
to drain from the tank. Flush the tank with water as needed
to remove sediment.
6. Close the drain valve, refill the tank, and restart the heater
as directed in this manual. If the water heater is going to
be shut down for an extended period, the drain valve should
be left open.
IMPORTANT: Condensation may occur when refilling the tank
and should not be confused with a tank leak.

Start Up Conditions
Thermal Expansion
Property Damage Hazard
• Avoid water heater damage.
• Install thermal expansion tank or device if necessary.
• Contact qualified installer or service agency.
As water is heated, it expands (thermal expansion). In a closed
system, the volume of water wilt grow. As the volume of water
grows, there wilt be a corresponding increase in water pressure
due to thermal expansion. Thermal expansion can cause
premature tank failure (leakage). This type of failure is not
covered under the limited warranty. Thermal expansion can also
cause intermittent temperature-pressure relief valve operation:
water discharged from the valve due to excessive pressure
build up. The temperature-pressure relief valve is not intended
for the constant relief of thermal expansion. This condition is not
covered under the limited warranty.
A properly sized thermal expansion tank should be installed
on all closed systems to control the harmful effects of 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 40.
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.

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
34
Whenever the water heater is filled with cold water, some
condensate will form while the burner is on. Awater heater may
appear to be leaking when in fact the water is condensation.
This usually happens when:
• A new water heater is filled with cold water for the first
time.
• 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.

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:
• a concentration of sulfate in the supply water.
• little or no dissolved oxygen in the water.
• 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.
Smelly water may be eliminated or reduced in some water
heater models by replacing the anode(s) with one of tess active
material, and then chlorinating the water heater tank and all
hot water lines. Contact Sears Service for further information
concerning this chlorination treatment and an anode replacement
kit #9001453. (For short heaters, use anode replacement
kit #9006299.) Anode replacement and chlorination of the tank
are not covered by the water heater's limited warranty.
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.
"AIR" In Hot Water Faucets
Explosion Hazard
• Flammable hydrogen
gases may be present.
• Keep all ignition sources
away from faucet when
turning on hot water.
35
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.
Safety Shut-off and Thermal Switch
This water heater is designed to automatically shut-off in the
event of the following:
1. The pilot flame is extinguished for any reason.
2. The water temperature exceeds 195°F (91°C).
3. Excessive build up of dust on the base ring filter or flame
arrestor. See Maintenance of your Water Heater Section.
4. The ignition of flammable vapors.
A thermocouple is used to determine if a pilot flame is
present, and wilt shut off the gas supply to the main
burner and the pilot if the flame is absent. This unit is also
equipped with a thermal switch, designed to shut off the gas
supply in the event the water heater has been exposed to
flammable vapors (e.g., spilled gasoline), poor combustion
caused by a blocked vent, or insufficient combustion air.
If the thermal switch opens:
1. Check the flame-arrestor for signs of high temperature (blue
or black discoloration). See Figure 36.
2,
Ifthere are signs of high temperature or that the thermal switch
has opened, inspect your installation for problems with venting,
combustion air supply, or a possible flammable vapor event.
(See "Pilot Light Troubleshooting Flowchart" section.) Correct
any issues prior to resetting the thermal switch. If you suspect
a flammable vapor incident has occurred, do not use this
appliance. Immediately call a qualified technician to inspect
the appliance. Water heaters subjected to aflammable vapors
ignition will require replacement of the entire water heater.
3. Reset the thermal switch by depressing the small button in the
center of the thermal switch. Follow the Lighting Instructions
found on the front of your water heater. A high temperature

Leakage Checkpoints
FIGURE 41.
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.
A. Water at the draft hood is water vapor which has condensed
out of the combustion products. This is caused by a
problem in the vent. Contact a qualified technician.
B. *Condensation may be seen on pipes in humid weather or
pipe connections may be leaking.
C. *The anode rod fitting may be leaking.
D. Small amounts of water from temperature-pressure relief
valve may be due to thermal expansion or high water
pressure in your area.
E. *The temperature-pressure relief valve may be leaking at
the tank fitting.
F. Water from a drain valve may be due to the valve being
slightly opened.
G. *The drain valve may be leaking at the tank fitting.
a.
Combustion products contain water vapor which can
condense on the cooler surfaces of the tank. Droplets form
and drip onto the burner or run on the floor. This is common
at the time of start-up after installation and when incoming
water is cold.
Water in the water heater bottom or on the floor may be
from condensation, loose connections, or the relief valve.
DO NOT replace the water heater until a full inspection
of all possible water sources is made and necessary
corrective steps taken.
Leakage from other appliances, water lines, or ground seepage
should also be checked.
To check where threaded portion enters tank, insert cotton
swab between jacket opening and fitting. If cotton is wet, follow
draining instructions in the "Draining and Flushing" section and
then remove fitting. Put pipe dope or teflon tape on the threads
and replace. When you are finished, follow the steps in "Filling
the Water Heater" in the Installation Instructions earlier in this
manual.
Read and understand instruction
manual and safety messages
before installing, operating or
servicing this water heater.
Failure to follow instructions and
safety messages could result in
death or serious injury.
Instruction Manual must remain
with water heater.
Read this manual first. Then, before checking the water heater,
make sure the gas supply has been turned "OFF", and never
turn the gas "ON" before the tank is completely full of water.
