Removing the Old Water Heater
®
4. Attach a hose to the water heater drain
valve and put the other end in a floor
drain or outdoors. Open the water
heater drain valve. Open a nearby hot
water faucet which will relieve
pressure in the water heater and speed
draining. 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.
FmGURE5.
Disconnect the vent pipe from the blower assembly 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. Make sure
existing vent complies with maximum and minimum vent lengths on
page 17.
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.
FIGURE2.
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.
Leave all gas appliances shut "OFF"
until the water heater installation is
completed, see Figures 2 and 3.

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.

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.

RGURE 6.
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.
RGURE 7.
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:
1. Select a location indoors as close as practical to the vent terminal or
location to which the water heater vent piping is going to be connected,
and as centralized with the water piping system as possible.
2. Selected location must provide adequate clearances for servicing
and proper operation of the water heater.
Property Damage Hazard
All water heaters eventually lea k.
, Do not install without adequate drainage.
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 hardware store. Such a drain pan
must have a minimum length and width of at least 2" (5.1 cm) greater than
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 resuJt in property
damage, even with the use of a 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 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 offthe
incoming water to the water heater when leakage is detected.
• 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.
• Devices that will turn off the gas supply to a gas water heater while at
the same time shutting off its water supply.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS)
ARE LIKELYTO BE PRESENT OR STORED (GARAGES, STORAGEAND
UTtLITYAREAS, 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
hot surface igniter or main burner. The resulting flashback and fire can
cause death or serious burns to anyone in the area. This water heater is
equipped with a FV sensor for detecting the presence of flammable
vapors, see Figure 8. When the sensor detects those vapors, the unit
will shut down and not operate. Should this happen, please refer to the
troubleshooting guide on pages 29°30. Even though this water heater is
a flammable vapors 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.

Also, the water heater must be located and/or protected so it is not
subiect to physical damage by a moving vehicle.
Fire Hazard
For continued protection against
riskoffire:
Do not install water heater on
carpeted floor.
Do not operate water heater if
flood damaged.
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" (7.6 cm) 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.

The results can be hazardous, and also cause product failure.
INSULATION BLANKETS
Insulation blankets are available to the general public for external use
on gas water heaters but 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 National Appliance Energy Conservation Act
standards with respect to insulation and standby loss requirements,
making an insulation blanket unnecessary.

COMBUSTION AIR AND VENTILAT_ON 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 cubic meters per kW) of the
aggregate input rating of a/appliances installed in that space. Rooms
communicating directly with the space in which the appliances are
insta/ed, 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 Ventlation

WATER PIPING
Water temperature over 125°F
(52°C) can cause severe burns
instantly resulting in severe iniury 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.
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, shall be used at the hot water taps used by these
people or at the water heater, see Figure 15. Valves for reducing point
of use temperature by mixing cold and hot water are also available:

Toxic chemicals, such as those used for boiler treatment shall not be
introduced into this system.
When the system requires water at temperatures higher than required
for domestic water purposes, a tempering valve must be installed. Please
refer to Figure 15 for suggested piping arrangement.
Water supply systems may, because of such events as high line
pressure, frequent cut-offs, 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.
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.
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.
Property Damage Hazard
. Avoid water heater damage.
, Install thermal expansion tank if necessary
. Do not apply heat to cold water inlet.
Contact qualified installer or Sears Service Center.
FIGURE 15.
Consult Sears Service Center. 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.
Toxic Chemical Hazard
- Do not connect to non=potable ,dater system.
This water heater shall not be connected to any heating system or
component or used as a nompotable water heating appliance.
All piping components connected to this unit shall be suitable for use
with potable water.
Figure !6 shows the typical attachment of the water piping to the water
heater. The water heater is equipped with 3/4 inch NPT water
connections.
NOTE: ff using copper tubing, solder tubing to an adapter before
attaching the adapter to the cold water inlet connection. Do not
solder the cold water supply line directly to the cold water inlet.
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 threaded end
of the threaded-to-sweat coupling and around both ends of the 3/4"
NPT threaded nipple. Using flexible connectors, connect the hot water
pipe to the hot water outlet on the water heater.

This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
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 and Automatic
Gas Shut-off Devices 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 = 1,035 kPa) 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 temperature@ressure 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 (! 5.2 cm) above, or at any distance below the structural floor.
Be certain that no contact is made with any live electrical part. The
discharge opening must not be blocked or reduced in size under any
circumstances. Excessive length, over 30 feet (9.14 m), or use of more
than four elbows can cause restriction and reduce the discharge
capacity of the valve, see Figures 16 or 20.
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"(15.2 cm) 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.

GAS PIPING
Fire and Explosion Hazard
- Do not use water heater with any
gas other than the gas shown on
the rating plate
" Excessive pressure to gas control
valve Can Cause serious injury or
death.
-Turn off gas lines during
[nstaNation.
" Contact qualified installer or
service agency.
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 (3.5
kPa) for natural and propane gas (L. R). The minimum inlet gas pressure
shown on the rating plate is that which will permit firing at rated input.
All gas piping must comply with local codes and ordinances or with the
National Fuel Gas Code (ANSI Z223.t / NFPA-54)whichever applies. Copper
and brass tubing and fittings (except tin lined copper tubing) shall not be used.
If the gas control valve is subjected to pressures exceeding 1/2 psi
(3.5 kPa), the damage to the gas control valve could result in a fire or
explosion from leaking gas.
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/NFPA54 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, and
• 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.

agency
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
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.
When installed at elevations above 7,700 feet (2,347 m), input rating
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 National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact
your local gas supplier for further information.
Failure to replace the standard orifice with a 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 safe limits. This could result in serious
injury or death. Contact your gas supplier for any specific changes
which may be required in your area.

VENT CONNECTIONS TO BLOWER ASSEMBLY
Figure 21 shows the optimal placement of the 2" to 3" or 3" to 4" reducer;
however, the vent can be reduced at any point in the vent system as long
as the maximum vent length is not exceeded.
Except where instructed in this manual, the mixing of 2", 3" and 4" vent
pipe is NOTALLOWED. If2" pipe is to be used, then a 2"to 3" bell reducer
is recommended. Figure 21 shows the recommended location for the
bell reducer. If the bell reducer is located at the rubber boot on the
blower assembly, then a short section of 3" vent pipe needs to be
installed in the rubber boot for proper connection of the 2" to 3" bell
reducer. That length can be the minimum length required for the connection.
If4" pipe is to be used, then a 3" to4" bell reducer is recommended.
Figure 21 showsthe recommended location for the bell reducer. Ifthe

HGURE21.
VENTING AND INSTALLATION
The water heaters covered by this manual are supplied with a 2" Schedule
40 PVC 22.5 ° Vent Terminal. If you decide to vent with 3" or 4" pipe, a
Schedule 40 DWV 45° Vent Terminal must be used. For your convenience,
we have included a screen for both 3" and 4" Vent Terminals.
Plan the layout of the vent system from the vent termination to the water
heater considering all of the 90 ° and 45 ° elbows plus the number of feet
of pipe that would be needed to install the total vent system. The water
heater must be vented to the outdoors as described in these instructions.
DO NOT connect this water heater to an existing vent or chimney. It must
be vented separately from all other appliances. Nonmetallic vent may be
used if it has "Heat Deflection Temperature" (HDT@66 psi) or 455 kPa of
at least 157°F or 69°C. Typical nonmetallic vent materials meeting this
requirement are: PVC (Schedule 40, ASTM D-1785), Coex Cellular Core
(Schedule 40, ASTM F-44! ), CPVC (Schedule 40, ASTM Do2846), ABS
(Schedule 40, ASTM Do2661 ). The fittings, other than the supplied Vent
Termination should be equivalent to the following: PVC (Schedule 40,
DWV, ASTM D-2665), CPVC (Schedule 40, DWV, ASTM F-438), ABS
(Schedule 40 DWV, ASTM Do2661 ).
The cement used should be as recommended by the vent pipe
manufacturer. See the instructions on pages 20 and 21 for the proper
method of cutting and cementing the PVC pipe and fittings.
The unit may be vented horizontally through a wall or vertically through
the roof. Pipe runs must be adequately supported along both vertical
and horizontal runs as follows:
• For Schedule 40, 2" PVC, ABS, Coex Cellular Core vent pipe: Every
3 feet (0.9 m).
• For Schedule 40, 3" PVC, ABS, Coex Cellular Core vent pipe: Every
3.5 feet (1.1 m).
• For Schedule 40, 4" PVC, ABS, Coex Cellular Core vent pipe: Every
4 feet (1.2 m).
• For Schedule 40, 2" CPVC vent pipe: Every 5 feet (1.5 m).
• For Schedule 40, 3" CPVC vent pipe: Every 6 feet (1.8 m).
The vent piping should be connected to the blower with a rubber
adapter and secured with hose clamps. The adapter and clamps are
provided with the heater.
Even though the flue gas temperature leaving the blower is between
140°F (69°C) and 175°F (79°C), some installations will have water
vapor condense in the vent piping. If this occurs, then adequate means
of draining and disposing of the condensate needs to be made by
the installer.
CONDENSATION
Condensate formation does not occur in all installations of power vented
water heaters, but should be protected against on installations where it
can form in the venting system. Condensation in the venting system of
power vented water heaters is dependent upon installation conditions
including, but not limited to ambient temperature and humidity of installation
location, ambient temperature and humidity of venting space, vent
discharge and slope, and product usage. In certain conditions, installations
in unconditioned space or having long horizontal or vertical vent runs
may accumulate condensate. In these conditions, the vent pipe should
be sloped downward away from the blower assembly 1/4" (6.4 mm) per
five feet (1.5 m) of pipe but not more than 1 1/2" (3.8 cm) in the total vent
length. If the vent piping is vented level or sloped upwards away from
the blower assembly, then adequate means for draining and disposing
of the condensate needs to be made by the installer (if condensate is
detected). If you have condensate, then a 3/8" drain hose can be connected
to the built-in drain port of the rubber boot on the blower assembly. For
your convenience, the rubber boot is supplied with a removable cap on
the built-in drain port. Prior to operating the water heater, make sure the
removable cap is installed on the drain port (ifa drain hose is not needed).
MAXIMUI_I VENT LENGTHS
• For Schedule 40, 4" CPVC vent pipe: Every 6.5 feet (2.0 m).
It is imperative that the first hanger (or support) be located on the horizontal
run immediately adjacent to the first 90-degree elbow from the vertical
rise. Support method used should isolate the vent pipe from the floor
joists or other structural members to prevent the transmission of noise
and vibration. Do not support, pin, or otherwise secure the venting
system in a way that restricts the normal thermal expansion and
contraction of the chosen venting material.
If the water heater is being installed as a replacement for an existing
power vented heater in pre-existing venting, a thorough inspection of
the existing venting system must be performed prior to any installation
work. Verify that the correct material as detailed above has been
used, and that the minimum or maximum vent lengths and terminal
location as detailed in this manual have been met. Carefully inspect the
entire venting system for any signs of cracks or fractures, particularly
at the joints between elbows and other fittings and the straight runs of
vent pipe. Check the system for signs of sagging or other stresses in
the joints as a result of misalignment of any components in the system.
If any of these conditions are found, they must be corrected in
accordance with the venting instructions in this manual before
completing the installation and putting the water heater into service.
40.000 BTU Units:
For 2" Venting, the maximum equivalent feet of pipe allowed
is 40 feet (12.2 m). This does not include the supplied vent termination
for the water heater. For the 2" venting, one 90 ° elbow is approximately
equal to 5 feet (1.5 m). One 45 ° elbow is approximately equal to 2.5
feet (0.8 m). It is recommended that at least 2 feet (0.6 m) of spacing
be used in between all 45 ° elbows and all 90°elbows.
For 3" Venting, the maximum equivalent feet of pipe allowed
is 120 feet (36.6 m). This does not include the Vent Termination (supplied
locally) for the water heater. For the 3" venting, one 90 ° elbow is
approximately equal to 5 feet (1.5 m). One 45 ° elbow is approximately

Fuel Gas Code, ANSi Z223.1/NFPA54, 7.3.4e and 7.8a,b, as follows:
1. The exit terminals of a mechanical vent system shall be not less
than 7 feet (2. ! 3 m) above grade when located adiacent to public
walkways, see Figure 23.
2. A venting system shall terminate at least 3 feet (91 cm) above any
forced air inlet located within 10 feet (3.1 m), see Figure 23.
3. The venting system shall terminate at least 4 feet (1.2 m) below, 4
feet (! .2 m) horizontally from or, 12 in. (30 cm) above any door,
window or gravity air inlet into any building.
The manufacturer also recommends that the vent termination should
not be installed closer than 3 feet (91 cm) from an inside corner of an
L shaped structure and not be less than 12 in. (30 cm) above grade.
The vent shall terminate a minimum of 12" (30.5 cm) above expected
snow, all level to prevent blockage of vent termination, see Figure 23.
4. In cold climates, it is recommended that vent termination not be mounted
directly above orwithin 3 feet (91 cm) horizontally from an oil tank vent or
gas meter to avoid potential freeze-up from condensation, see Figure 23.
Plan the vent system layout so that proper clearances are maintained
from plumbing and wiring.
Vent pipes serving power vented appliances are classified by building
codes as "vent connectors". Required clearances from combustible
materials must be provided in accordance with information in this manual
under FACTS TO CONSIDER ABOUT THE LOCATION and VENT
TERMINAL INSTALLATIONS, and with the National Fuel Gas Code and
local codes.
VENT TERMINAL INSTALLATION
After the point of termination has been determined, use the cover
plate as a template to mark the hole for the vent pipe to insert
through the wall. BEWARE OF CONCEALED WIRING AND PIPING
INSIDE OFWALL
If the Vent Terminal is being installed on the outside of a finished
wall, it may be easier to mark both the inside and outside walk
Align the holes by drilling a hole through the center of the template
from the inside through to the outside. The template can now be
positioned on the outside wall using the drilled hole as a centering
point for the template.
A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch larger than the
marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch outside of the
marked circle. This pilot hole is used as a starting point for a
saws=all or sabre saw blade. Cut around the marked circle staying
approximately one quarter inch outside of the line. (This will allow
the vent pipe to easily slide through the opening. The resulting
gap will be covered up by the vent terminal cover plates.) Repeat
this step on inside wall if necessary.
When the vent piping cannot pass through an outside wall at a
height greater than or equal to 12" above the ground (or above
snow accumulation level), then the installation can be modified as
shown below.

not a requirement for the vent termination (if not needed by the installer).
VERTICAL VENT THROUGH ROOF
This unit is approved for venting through the roof with the type vent
terminal that is included with the unit. A proper flashing or "BOOT"
should be used to seal the pipe where it exits the roof.
The total vent system should not exceed that which is specified, see

VENT PIPE PREPARATION
1. INITIAL PREPARATION
A. Make sure the solvent cement you are planning to use is
designed for the specific application you are attempting.
B. Knowthe physical and chemical characteristics and limitations
of the PVC and CPVC piping materials that you are about to use.
C. Know the reputation of your manufacturer and their products.
D. Know your own qualifications or those of your contractor.
The solvent welding technique of joining PVC and CPVC pipe
is a specialized skill just as any other pipe fitting technique.
E Closely supervise the installation and inspect the finished
job before start-up.
R Contact the manufacturer, supplier, or competent consulting
agency if you have any questions about the application or
installation of PVC and CPVC pipe.
G
Take the time and effort to do a professional job. Shortcuts
will only cause you problems and delays in start-up. By far,
the majority of failures in PVC and CPVC systems are the
result of shortcuts and/or improper ioining techniques.
2. SELECTmON OF MATERIALS
Cutting Device - Saw or Pipe Cutter
Deburring Tool, Knife, File, or Beveling Machine (2" and above)
Brush - Pure Bristle
Rag - Cotton (Not Synthetic)
Primer and Cleaner
SoNent Cement - PVC for PVC Components and CPVC for CPVC
Components
Containers - Metal or Glass to hold Primer and Cement. Select the
type of PVC or CPVC materials to be used on the basis of their
application with respect to chemical resistance, pressure rating,
temperature characteristics, etc.
Insertion Tool - Helpful for larger diameter pipe and fittings 6 inches
(15.2 cm) and above.
PRIMER
It is recommended that Tetrahydrofuran (THF) be used to prepare the
surfaces of pipe and fittings for solvent welding. Do not use water,
rags, gasoline or any other substitutes for cleaning PVC or CPVC
surfaces. Achemical cleaner such as MEK may be used.
CEMENT
The cement should be a bodied cement of approximately 500 to 1600
centipoise viscosity containing 10-20% (by weight) virgin PVC material
solvated with tetrahydrofuran (THF). Small quantities of dimethyl
formamide (DMF) may be included to act as a retarding agent to extend
curing time. Select the proper cement; Schedule 40 cement should be
used for Schedule 40 pipe. Never use all-purpose cements, commercial
glues and adhesives orABS cement to join PVC or CPVC pipe and fittings.
Fire Hazard
P_imereand earr_nts are extremelyflammable, and
must not be stored or used near heat or open flame.
, Also, use only in a well ventilated area.
APPUCATORS
Select a suitable pure bristle type paint brush. Use a proper width
brush or roller to apply the primer and cement (see chart below).
Speedy application of cement is important due to its fast drying
characteristics. IMPORTANT NOTE: A dauber type applicator should
only be used on pipe sizes 2" and below. For larger diameter pipe, a
brush or roller must be used.

3. MAKING THE JOINT
A, Cutting
Pipe must be squarely cut to allow for the proper interfacing of the
pipe end and the fitting socket bottom. This can be accomplished
with a miter box saw or wheel type cutter. Wheel type cutters are
not generally recommended for larger diameters since they tend to
flare the corner of the pipe end. If this type of cutter is used, the
flare on the end must be completely removed.
NOTE: Power saws should be specifically designed to cut plastic pipe.

1(
STEP B
C. Test dry fit of the joint
Tapered fitting sockets are designed so that an interfaced fit should
occur when the pipe is inserted about 1/3 to 2/3 of the way into the
socket. Occasionally, when pipe fitting dimensions are at the
tolerance extremes, it will be poseible to fully insert dry pipe to the
bottom of the fitting socket. When this happens, a sufficient quantity
of cement must be applied to the joint to fill the gap between the pipe
and fitting. The gap must be filled to obtain a strong, leakofreeioint.
D. Inspection, cleaning, priming
Visually inspect the inside of the pipe and fitting sockets and remove
all dirt, grease or moisture with a clean dry rag. If wiping fails to
clean the surfaces, a chemical cleaner must be used. Check for
possible damage such as splits or cracks and replace if necessary.
Depthoofoentry
Marking the depth of entry is a way to check if the pipehas reached
the bottom of the fitting socket in Step R Measure the fitting depth
and mark this distance on the pipe O.D. You may want to add
several inches to the distance and make a second mark as the
primer and cement will most likely destroy your first one.
Apply primer to the surface of the pipe and fitting socket with a natural
bristle brush. This process softens and prepares the PVC or CPMC for
the solvent cementing step. Move quickly and without hesitation to the
cementing procedure while the surfaces are still wet with primer.
E, Application of solvent cement
. Apply the selvent cement evenly and quickly around the outside of the
pipe at a width a little greater than the depth of the fitting socket.
. Apply a light coat of cement evenly around the inside of the
fitting socket. Avoid puddling.
• Apply a second coat of cement to the pipe end.
Cons of cement and primer should be closed at all
times when not in use to prevent evaporation of
chemicals and hardening of cement.
They are also very flammable and should be kept
away from heat or flame.
R Joint assembmy
STEPE
Working quickly, insert the pipe into the fitting socket bottom and
give the pipe or fitting a 1/4 turn to evenly distribute the cement. Do
not continue to rotate the pipe after it has hit the bottom of the fitting
socket. A good joint will have sufficient cement to make a bead all
the way around the outside of the fitting hub. The fitting will have a
tendency to slide back while the cement is still wet so hold the ioint
together for about 15 seconds.
G,
f,
STEPF
Cleanup and joint movement
Remove all excess cement from around the pipe and fitting with a
dry cotton rag. This must be done while the cement is still soft.
The ioint should not be disturbed immediately after the cementing
procedure, and sufficient time should be allowed for proper curing
of the joint. Exact drying time is difficult to predict because itdepends
on variables such as temperature, humidity and cement integrity.
For more specific information, you should contact your solvent
cement manufacturer.

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.
Any water heater's intended purpose is to heat water. Hot water is
needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing).
Untempered hot water can present a scald hazard. Depending on the
time element, and the people involved (adults, children, elderly, infirm,
etc.) scalding may occur at different temperatures.
It is recommended that lower water temperatures be used to avoid the
risk of scalding. It is further recommended, in all cases, that the water
temperature be set for the lowest temperature which satisfies your
hot water needs. This will also provide the most energy efficient
operation of the water heater.
Figure 26 shows the approximate water temperatures produced at
various thermostat settings. Short repeated heating cycles caused by
small hot water uses can cause temperatures at the point of use to
exceed the thermostat setting by up to 30°F (17°C). If you experience
this type of use you should consider using lower temperature settings
to reduce scald hazards.
Valves for reducing the point-of-use temperature by mixing cold and
hot water are available, see Figure 15. Also available are inexpensive
devices that attach to faucets to limit hot water temperatures. Contact
a licensed plumber or the local plumbing authority.
Water temperature over 125°F
(52°0) can cause severe burns
instantly resulting in severe iniury 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.
HOT 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, shall 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 !5.
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, see Figure 26.
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.
The water heater should be located in an area where the general
public does not have access.
The water temperature setting was factory set at the lowest
temperature; Press ng the "COOLER":-_... button decreases temperature
and pressing the "HOTTER",:_::_} button increases the temperature.
Setting the water heater temperature at 120°F (4g°c) (Approx. "V"
mark on temperature setting of gas valve) will reduce the risk of scalds.
Some states require settings at specific lower temperatures.
To avoid any unintentional changes in water temperature settings, the
control has a tamper resistant feature for changing the temperature
setting. To change the temperature setting follow these instructions:
1. "Wake Up" the temperature indicators by holding down both
"COOLER" and "HOTTER" temperature adjustment buttons at the
same time for one second, see Figure 26. One or two of the
temperature indicators will light up. These indicators will only remain
on for 30 seconds if no further buttons are pressed. After 30 seconds
the control will go back to "Sleep" mode.
2. Release both of the temperature adjustment buttons.
a. To decrease the temperature press and release the "COOLER"
button until the desired setting is reached.
b. To increase the temperature press and release the "HOTTER"
button until the desired setting is reached.
NOTE: Holding down the button will not continue to lower or raise the
temperature setting. The button must be pressed and released for
each temperature change desired.
Should overheating occur or the gas supply fail to shut off, turn off the
manual gas control valve to the appliance.

START U P CONDmONS
CONDENSATE
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 condensate. This usually happens when:
a. A new water heater is filled with cold water for the first time.
b. Burning gas produces water vapor in water heaters, particularly
high efficiency models where flue temperatures are lower.
c. 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.
Because of the suddenness and amount of water, condensate 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 condensate may be noticed during the winter and eady
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.
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.
THERMAL EXPANSmON
improper installation and use may resamt
in property damage,
Avoid water heater damage.
. Install thermal expansion tank or device if necessary.
. Contact qualified installer or Sears Service Center,
Water supply systems may, because of such events as high line
pressure, frequent cut-offs, 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 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
release 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 in the
water system. Expansion tanks are available through Sears stores
and Sears Service Centers. Contact Sears Service Center for
assistance in controlling these situations, see Figure 27.

harmful or dangerous conditions.
Condensation causes sizzling and popping within the burner area during
heating and cooling periods and should be considered normal. See
"Condensate" in this section.
OPERATIONAL CONDITIONS
SMELLYWATER
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" in the hot water. The smell is a result of four factors
which must all be present for the odor to develop:
a. A concentration of sulfate in the supply water.
b. Little or no dissolved oxygen in the water.
c. A sulfate reducing bacteria which has accumulated within the water
heater (this harmless bacteria is nontoxic to humans).
d. 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 less active material, and
then chlorinating the water heater tank and all water lines. Contact
Sears Service Center for further information concerning 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.
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.
Do not remove the anode leaving the tank unprotected, By
doing so, aH warranty on the water heater tank is voided.
"AmR"mNNOT WATER FAUCETS
E×plosion Hazard
" Flammable hydrogen gases may be present
• Keep all ignition sources away from faucet
when turning on hot water,
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.
HIGH WATER TEMPERATURE SHUT OFF SYSTEM
This water heater is equipped with an automatic gas shut-off system.
This system works when high water temperatures are present. Turn
"OFF" the entire gas supply to the water heater. The high temperature
shut-off is built into the gas control valve. It is non-resettable. If the high
temperature shut-off activates, the gas control valve must be replaced.
Contact your gas supplier or Sears Service Center.
VENTING SYSTEM INSPECTION
Breathing Hazard o Carbon Monoxide Gas
_, 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.
Chemical corrosion of flue and vent
system can cause serious iniury or
death.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual.
At least once a year a visual inspection should be made of the venting
system. You should look for:
1. Obstructions which could cause improper venting. The combustion
and ventilation air flow must not be obstructed.
2. Damage or deterioration which could cause improper venting or
leakage of combustion products.
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 after inspection of the vent system you found sooting or deterioration,
something is wrong. Call the local gas utility to correct the problem and
clean or replace the flue and venting before resuming operation of the
water heater.

INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and
combustion air supply, proper clearances from the water heater must
be maintained. See "Facts to ConsiderAbout the Location" section.
Combustible materials such as clothing, cleaning materials, or flammable
liquids, etc. must not be placed against or adiacent to the water heater
which can cause a fire.
ANODE ROD INSPECTION
Property Damage Hazard
Avoid water heater damage.
Inspection and replacement of anode rod required.
FIGURE 28.
BURNER CLEANING
In the event your burner or burner air openings require cleaning, turn
the blower switch to the "OFF" position and allow the burner to cool.
Call Sears Service Center to remove and clean the burner and correct
the problem that required the burner to be cleaned.
HOUSEKEEPING
Vacuumaround baseof waterheaterfordust,dirt,andlinton a regularbasis.
Fire and Expmosion 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.
* Visibly inspect air intake screen at
least once every six months and
clean if accumulated lint.
, Can cause serious injury or death.
This water heater unit is supplied with a plasticAir intake Screen that will
filter and prevent lint build°up on the bottom of the flame arrestor of this
heater. To prevent the lint build-up on the arrestor, the lint screen must be
installed on the Base Pan with the "arrows" pointing upwards as shown
in Figure 29. If theAir intake Screen is missing from this heater, please
contact Sears Service Center for a replacement part.
The anode rod is used to protect the tank from corrosion. Most hot
water tanks are equipped with an anode rod. The submerged rod
sacrifices itself 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 a qualified technician, and at a minimum should be
checked annually after the warranty period.
TEMPERATURE-PRESSURE
REUEF VALVE OPERATION
Burn hazard
• Hot water discharge.
Keep clear of relief valve
discharge outlet.
26
The temperature-pressure relief valve must be manually operated at
least once a year.
TEMPERATURE=PRESSURE
DISCHARGEPiPE
FIGURE 30.
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 30.
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.
ifthe temperature=pre_ure relief valve on the appliance weeps or discharges
periodically, this may be due to then_al expansion. You may have a check
valve installed in the water line or a water meter with a check valve. Consult
yourlocalwatersupplierorSearsServiceCenterfor furtherinformation. Do
not plug the temperature=pressure relief valve.
DRAINING
,, Burn hazard
- Hot water discharge.
• Keep hands clear of drain
valve discharge.
The water heater should be drained if being shut down during freezing
temperatures. Also periodic draining and cleaning of sediment from the
tank may be necessary.
1. Set the blower switch to the "OFF" position.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearbyhotwaterfaucetand leaveopentoallowfor draining.
4. Connect a hose to the drain valve and terminate to an adequate drain.
5. OPEN the water heater drain valve to allow for tank draining.
NOTE: mfthe water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected amlowing water to terminate
to an adequate drain.
6. CLOSE the drain valve.
7. Follow instructions in the "Filling The Water Heater" section.
8. Follow the lighting instructions on the label or see page 22 under
"Operating instructions" to restart the water heater.

Usethisguidetochecka"Leaking"waterheater.Manysuspected
"Leakers" are not leaking tanks. Often the source of the water can be
found and corrected.
If you are not thoroughly familiar with gas codes, your water heater, and
safety practices, contact Sears Service Center to check the 'water heater.
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 inju ry_
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.
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 blower assembly is water vapor which has condensed
out of the combustion products. This is caused by a problem in the
vent. Contact the gas utility.
B. *Condensation may be seen on pipes in humid weather or pipe
connections may be leaking.
C. *The anode rod fitting may be leaking (anode is located under the
Blower Assembly).
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.
R 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.
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 startoup
after installation and when incoming water is cold.
Water in the water heater bottom or on the floor may be from
condensation, loose connections, orthe 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 "Periodic Maintenance" section and then remove
fitting. Put pipe dope or teflon tape on the threads and replace.
Then follow"Filling the Water Heater" instructions in the "Installation
Instructions" section.
