sl “OFF” to the water heater. Next, unplug the water heater
— (cord set) or disconnect the electrical supply connection from
| the water heater junction box.
FIGURE 4
Ba. 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. This will avoid cutting off the pipes too short.
Additional cuts can be made later if necessary. Disconnect
the temperature-pressure relief valve drain line. When
the water heater is drained, disconnect the hose from the
drain valve. Close the drain valve. The water heater is now
completely disconnected and ready to be removed.
FIGURE 1
2. Open a nearby hot water faucet until the water is no longer
hot. When the water has cooled, turn “OFF” the water supply
to the water heater at the water shut-off valve or water meter.
FIGURE 2 FIGURE 5
3. Attach a hose to the water heater drain valve and put the
other end in a floor drain or outdoors. Open the water drain
valve. Open a nearby hot water faucet, which will relieve
pressure in the water heater and speed draining.
Bb. If you have galvanized pipe 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.
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.

o |[fspilled, could cause staining.
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.
Facts to Consider About the Location
You should 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
intended for outdoor installation.
Whether replacing an old water heater or putting the water
heater in a new location, the following critical points must be
observed.
* The location selected should be indoors as close to and as
centralized with the water piping system as possible. This
water heater, as well as all water heaters, will eventually leak.
Do not install without adequate drainage provisions so water
flow will not cause damage.
CAUTION
Property Damage Hazard
« Allwater heaters eventually leak
* Do notinstall without adequate drainage.
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater must be accomplished in such a manner that if the tank
or any connections should leak, the flow of water will not cause
damage to the structure. When such locations cannot be avoided,
a suitable drain pan should be installed under the water heater.
Drain pans are available at your local Sears stores. Such drain
pans must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a drain pan piped
to a drain. 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 off the 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.
CAUTION
Installations in Residential Garages
*e \Water heater must be located in a
protective area.
INSTALLATION IN RESIDENTIAL GARAGES: The water heater
must be located and/or protected so it is not subject to physical
damage by a moving vehicle.
* The location selection must provide adequate clearances
for servicing and proper operation of the water heater.
Wiring
MWARNING_ И
Electric Shock Hazard
Disconnect power before
servicing.
Replace all parts and panels
before operating.
Failure to do so can result in
death or electric shock.
ENT.
Fire Hazard
Use 10 gauge solid copper wire.
Use a UL approved strain relief.
Connect ground wire to green
ground screw.
Failure to do so can result in
death, fire, or electrical shock.
If you lack the necessary skills required to properly install the
electrical wiring to this water heater, do not proceed, but have a
qualified electrician perform the installation.
When making the electrical connections, always make sure:
* The electrical supply has the proper overload fuse or circuit
breaker protection.
+ Wire sizes and connections comply with all applicable
codes.
+ Wiring is enclosed in approved conduit (if required by local
codes).
1.
2.
3.
The water heater and electrical supply are properly
grounded.
Always reference the wiring diagram for the correct electrical
connection. The complete wiring diagram can also be found
on the top of the water heater near the junction box cover.
Although this water heater is equipped with “Dry-fire”
protection, be sure the tank is completely filled with
water, and all air is purged from the tank before
making any electrical connections. See Figure 7.
Heating Element
NOTE: Applying electrical power to elements that are not submerged
in water will destroy them. The manufacturer will not warrant any
elements damaged in this manner.
FIGURE 7
Check and turn off power to the electrical wiring of the
water heater before making any electrical connections to
the water heater.
Remove the junction box cover that is secured by one
screw (Figure 9). Place the cover and screw aside and view
the wiring diagram. Locate the four power wires inside the
junction box (there will be TWO red wires and TWO black
wires).
Connect the electrical supply to the water heater in
accordance with the local utility requirements and codes. A
standard 1/2 inch opening has been made in the junction
box for the conduit connections (Figure 9). NOTE: Use only
10 gauge solid copper wire for the electrical connections and
an appropriately-sized double pole circuit breaker.
A WARNING
Fire Hazard
Use 10 gauge solid copper wire.
Use a UL approved strain relief.
Connect ground wire to green
ground screw.
Failure to do so can result in
death, fire, or electrical shock.
4.
Ground the water heater by connecting the bare copper ground
wire from the home's electrical service to the green ground
screw (located inside the electrical junction box on top of the
water heater). See Figure 8 and Figure 9.
5. There are TWO black wires and TWO red wires in the water
heater. The smaller red and black wires are used by the
Kenmore Smart connector port.
6. Connect the black power wire from the home's electrical
service to the heater's TWO black wires and secure with the
appropriate size wire nut. When you are done, you will have
THREE black wires under one wire nut.
7. Locate and connect the remaining power wire (usually
red, but in your home, this wire may be some other
color) from the home's electrical service to the water heater's
TWO red wires and secure with the appropriate size wire nut.
10
When you are finished, you will have THREE red wires under
one wire nut (depending on the actual color of your home's
electric wiring).

Water Piping
Water temperature over 125°F
(52°C) can cause severe 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.
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
will satisfy 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 challenged. 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. Use the lowest
possible temperature setting that satisfies your hot water needs.
Also, to reduce the risk of scalding, the manufacturer of this water
heater recommends installing a mixing valve at each point of use.
install thermostatic mixing valves (temperature limiting valves) at
each point of use. Mixing valves are available at plumbing supply
or hardware stores. Follow the manufacturer's instructions for
installation of the valves. Before changing the factory setting
on the thermostat, read the “Temperature Regulation” section
in this manual.
Piping, fittings, and valves should be installed according to the
installation drawing (Figure 11). If the indoor installation area
is subject to freezing temperatures, the water piping must be
protected by insulation.
Water supply pressure should be around 50 to 60 psi and should
not exceed 80 psi. If this occurs, a pressure reducing valve
should 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 connec-
tions 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 fitting as shown in
Figure 11. Connect the cold water supply (3/4" NPT)
to the fitting marked “Cold”. Connect the hot water
supply (3/4” NPT) to the fitting marked “Hot”.
IMPORTANT: Some models may contain energy saving heat
traps to prevent the circulation of hot water within the pipes.
Do not remove these inserts.
2. The Installation of dielectric unions in both the hot
and cold water supply lines is recommended for
ease of removing the water heater for service or
replacement.
3. Install thermostatic mixing valves (temperature limiting
valves) at each point of use. These valves reduce the point-
of-use temperature of the hot water by mixing cold and hot
water and are readily available. Contact a licensed plumber
or the local plumbing authority.
À. If installing the water heater in a closed water
system, install a relief valve or expansion tank in
the cold water line as specified under “Closed
System/Thermal Expansion”.
5. 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.

* DO NOT install this water heater with iron piping.
The system should be installed only with piping that
is suitable for potable (drinkable) water such as
copper, CPVC, or polyethylene (PEX).
* DO NOT use PVC water piping.
* DO NOT use any pumps, valves, or fittings that are
not compatible with potable water.
* DO NOT use valves that may cause excessive
+ restriction to water flow. Use full-flow ball or gate valves only.
* DO NOT use tin-lead solder in potable water lines.
Use 95/5 tin antimony or other equivalent material.
* DO NOT tamper with the electronic thermostat, temperature
sensors, heating elements, electrical connections, or
temperature and pressure relief valve. Tampering voids all
warranties. Only qualified service technicians should service
these components.
* DO NOT use with piping that has been treated with
chromates, boiler seal, or other chemicals.
* DO NOT add any chemicals to the system piping which will
contaminate the potable water supply.

pee
Properly sized temperature-
pressure relief valve must be
installed in opening provided.
Do not plug, block, or cap the
discharge line.
Failure to follow this warning
can result in excessive tank
pressure, serious injury or
death.
A
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 for Hot Water Supply Systems, ANSI Z21.22 + CSA4.4,
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 electric heaters, watts x 3.412 equals Btu/hr input rate).
For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designed for the relief valve.
Position the valve opening downward and provide tubing so
that any discharge will exit only within 6 inches above, or at any
distance below the structural floor. Be certain that no contact is
made with any live electrical part. The discharge opening must not
be blocked or reduced in size under any circumstances. Excessive
length, over 30 feet (9.14 m), or use of more than four elbows can
cause restriction and reduce the discharge capacity of the valve.
CAUTION
Water Damage Hazard
» Temperature-pressure relief valve discharge
pipe must terminate at adequate drain.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connect tubing directly to
discharge drain unless a 6 inch air gap is provided. To prevent
bodily injury, hazard to life, or property damage, the relief
valve must be allowed to discharge water in quantities should
circumstances demand. If the discharge pipe is not connected
to a drain or other suitable means, the water flow may cause
property damage.
The Discharge Pipe:
* Mustnotbe smaller in size than the outlet pipe size of the valve,
or have any reducing couplings ofr other restrictions.
* Must not be plugged or blocked.
« Must be of material listed for hot water distribution.
* Mustbe installed so as to allow complete drainage of both the
temperature-pressure relief valve, and the discharge pipe.
* Must terminate a maximum of six inches above a floor
drain or external to the building. In cold climates, it is
recommended that the discharge pipe be terminated at an
adequate drain inside the building.
* Must terminate at an adequate drain.
* Must not have any shut-off valve between the relief valve and
tank nor in the discharge pipe.

insulation has been exposed to water in any way. Immediately
call a qualified service technician to inspect the water heater and
replace any temperature sensor(s), electronic control board, or
insulation that has been exposed to water. Do not attempt to
repair these parts. Water heaters subjected to flood conditions
or any time the temperature sensor(s) or electronic thermostat
have been submerged in water require replacement of the entire
water heater.
Safety Shut-Off
This water heater is designed to automatically shut-off in the
event that the water temperature exceeds 180° F (82.2° C). A
temperature limit switch, or ECO (Energy Cut Off), is used to shut
off the power to the system if the water temperature exceeds
180° F or 82.2° C. The ECO can be reset by firmly pushing in
the red reset button located on the electronic thermostat. (See
Figure 14 on page 17.) If the ECO continues to shut-off the

When leaving your home for extended periods (vacations, etc.)
set the water heater to Vacation Mode. This will maintain the
water at low temperatures with minimum energy losses and
prevent the tank from freezing during cold weather.
NOTE: When returning from an extended stay, remember to set
the water heater back to the desired Operational Mode.
The Electronic Thermostat
IMPORTANT: If installed - the Kenmore Smart Water Heater
Module (purchased separately) must be removed before
attempting to adjust the thermostat. NOTE: For the Electronic
Thermostat (ET) changes to remain in effect, the Kenmore Smart
Water Heater Module must not be reconnected. Also read the
“Water Temperature Regulation” under the “Operating Your
Water Heater” section. If the instructions are not clear, contact
a qualified service technician.
Water Temperature Adjustment
The Electronic Thermostat (ET) may be accessed by removing the
upper Access Door (See Figure 15). Adjust the set temperature by
rotating the set point knob right or left for the desired temperature
(See Figure 14). The Electronic Thermostat consists of an
electronics box that contains a low voltage power supply, the
thermostat set point knob, relays to switch between the upper
and lower heating elements, one control thermistor, a connector
for the lower element control thermistor, microelectronics to
convert the thermistor signals and perform switching and other
logic functions, and a connector to tie the Electronic Thermostat
(ET) to the Kenmore Smart Water Heater Module (purchased
separately) located on the top of the water heater. The majority
of the self-diagnostics are located in the Electronic Thermostat
(ET), including the dry-fire protection intelligence. The thermostat
circuit is designed so that when the upper heating element calls
for heat, the power is directed to that element even if the lower
element is also calling for heat.
Diagnostic LED Light
The Green/Red LED light indicates the status of the electronic
thermostat (Figure 14).
* Green LED will signal normal operation. The green LED will
blink 2 times per second to indicate that power is applied to the
upper heating element and at a faster rate (4 times per second)
to indicate that the lower heating element is powered.
- Red LED will flash error codes. If a fault is detected by the
electronic thermostat, the LED light indicator will use the red
LED to indicate the fault detected. The flash code sequence is
to consist of 1/2 second flashes of the red LED each separated
by a 1/2 second off period.
The number of flashes indicates the fauit code number.
(See diagnostic code chart section in this manual).
After the last 1/2 second “on” period, the LED will remain off
until a total of 5 seconds has elapsed for the fault indication
cycle (there is a 5 seconds delay before the fault flash pattern
repeats). After the 5 seconds are completed, the fault indication
cycle is repeated starting with the first 1/2 second-flash. The
flash sequence will be repeated as long as the fault remains.
Only one fault can be declared at a time. NOTE: the green LED
is turned off when a fault code is being displayed, even though
the heater may be operating in limp mode with an element on.
See diagnostic code chart section in this manual.
Overriding The Electronic Thermostat
With the installation of a Kenmore Smart Water Heater Module
(purchased separately), the water heater temperature may be
adjusted remotely. (See instructions supplied with the Kenmore
Smart Water Heater Module).

SERVICE AND ADJUSTMENT
If you lack the necessary skills required to service this water
heater properly, or if you have difficulty following the instructions,
you should not proceed. Have a qualified service technician
perform the maintenance of this water heater.
Anode Rod Inspection
CAUTION
Property Damage Hazard
» Avoid water heater damage.
* Inspection and replacement of anode as needed.
See also “Smelly Water” on page 22.
Each water heater contains at least one anode rod, which will
slowly deplete (due fo electrolysis), prolonging the life of the
water heater by protecting the glass-lined tank from corrosion.
Adverse water quality, hotter water temperatures, high hot water
usage, hydronic heating devices, and water softening methods
can increase the rate of anode rod depletion. Once the anode rod
is depleted, the tank will start to corrode, eventually developing
a leak.
Certain water conditions will cause a reaction between the anode
rod and the water. The most common complaint associated with
the anode rod is a “rotten egg smell” produced from the presence
of hydrogen sulfide gas dissolved in the water. CAUTION: Do
not remove this rod permanently as it will void any warranties. A
special anode rod may be available if water odor or discoloration
occurs. NOTE: this rod may reduce but not eliminate water odor
problems. The water supply system may require special filtration
equipment from a water conditioning company to successfully
eliminate all water odor problems.
Artificially softened water is exceedingly corrosive because the
process substitutes sodium ions for magnesium and calcium ions.
The anode rod should be inspected after a maximum of three
years and annually thereafter until the condition of the anode
rod dictates its replacement. NOTE: Artificially softened water
requires the anode rod to be inspected annually.
The following are typical (but not all) signs of a depleted anode
rod:
* The majority of the rods diameter is less than 3/8”.
* Significant sections of the support wire (approx. 1/3 or
more of the anode rod's length) are visible.
If the anode rod shows signs of either or both it should be
replaced (Figure 16). NOTE: Whether re-installing of replacing
the anode rod, check for any leaks and immediately correct if
found.

TROUBLESHOOTING
Start Up Conditions
CLOSED SYSTEM/THERMAL EXPANSION
CAUTION
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 will increase. As the volume of
water increases, 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

STRANGE SOUNDS
Possible noises due to expansion and contraction of some
metal parts during periods of heat-up and cool-down do not
represent harmful or dangerous conditions.
Operational Conditions
SMELLY WATER
See also “Anode Rod Inspection” on page 19.
In each glass-lined water heater there is installed 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. A concentration of sulfate in the supply water.
B. Little or no dissolved oxygen in the water.
C. A sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic 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 rod (s) with one of less active
material, and then chlorinating the water heater tank and all hot
water lines. Contact the local Sears Service Center for further
information concerning an Anode Replacement Kit #9001453
and this Chlorination Treatment. Anode replacement and
chlorination of the tank are not covered by the water heater’s
limited warranty.
If the smelly water persists after the anode replacement and
chlorination treatment, then you should consider chlorinating or
aerating your water supply.
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
> A WARNING
Explosion 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
be opened for several minutes at the kitchen sink before any
electrical appliances which are connected to the hot water
system are used (such as a 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.
RUMBLING NOISE
In some water areas, scale or mineral deposits will build up on
your heating elements. This buildup will cause a rumbling noise.
Follow “Element Cleaning/Replacement” instructions to clean
and replace the elements.
23
HIGH TEMPERATURE SHUT OFF SYSTEM
The water heater has a high limit shut off system with a reset
button located on the thermostat. Follow the resetting instructions
which refer to the high limit behind the access panel.
A WARNING
* Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned “OFF”.
Ww
* Failure to do this could result in
death, serious bodily injury, or
property damage.
1. Before beginning, turn “OFF” electrical power supply to the
water heater.
——
FIGURE 21
2. Remove the screw securing the access panel and remove
the panel.
3. Fold the insulation back to expose the thermostat.
4. Resetthe high limit by pressing the ECO reset button on the
electronic thermostat. See Figure 14 on page 17. Replace
the insulation so that it completely covers the thermostat and
element.
5. Replace the access panel.
6. Turn “ON” electric power to the water heater.
If the high limit must be reset again, call Sears Service
Department to find out why the high limit turned “OFF” the
electric power.
NOT ENOUGH OR NO HOT WATER
1.
In a new installation, the water heater may not be properly
connected. Make sure the cold water supply valve is open.
Review and check piping installation. Make sure that the
cold water line is connected to the cold water inlet to the
water heater and the hot water line to the hot water outlet
on the water heater.
Make sure the electrical supply to your water heater is “ON”,
Check for loose or blown fuses in your water heater circuit.
Circuit breakers weaken with age and may not handle their
rated load and should be replaced.
Make certain the disconnect switch, if used, is in the “ON”
position.
Check to see the electric service to your house has not been
interrupted. If this is the case, contact the electric company.
Is the thermostat set to the desired temperature? See
the “Temperature Regulation” and “Water Temperature
Adjustment” sections.
If you had experienced very hot water and now no hot water,
the problem may be due to the high temperature shut off
system. See “High Temperature Shut Off System” in the
“Troubleshooting” section.
During very cold weather, the incoming water will also be
colder and it will require a longer time to become heated.
9. The hot water usage may exceed the capacity of the water
heater. If so, wait for water heater to recover after abnormal
demand. Also examine pipes and faucets for possible water
leaks.
10. If you can not determine the problem, then call the Sears
Service Department.
WATER IS TOO HOT
Adjust the thermostat {o a lower setting. See the “Temperature
Regulation” and “Water Temperature Adjustment” sections.
STACKING
Certain water usage patterns can cause the water temperature
to exceed the thermostat setting. This is known as “Stacking”.
Stacking occurs when a series of short draws of hot
water (3 gallons or less) are taken from the water heater tank.
This causes increased cycling of the heater elements and can
result in increased water temperatures at the hot water outlet.
To reduce the risk of scalding, install thermostatic mixing valves
(temperature limiting valves) at each point of use. Mixing valves
are available at local hardware stores.
24
Diagnostic Code Chart: Electronic Thermostat (ET)
Refer to the table below and on the following
page.
IMPORTANT: Before attempting to adjust the
thermostat, read the “Water Temperature Regulation”
section on page 16.
The Electronic Thermostat (ET) is designed so that
it may control the water heater without the optional
Kenmore Smart Water Heater Module being operated.
See page 17.
