Removing the Old Water Heater
FIGURE 1.
1. Turn “OFF” electrical supply to the water heater.
FIGURE 2.
2. Turn “OFF” the water supply to the water heater at the water
shut-off valve or water meter.
FIGURE 3.
3. 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.
FIGURE 4.
INSTALLATION INSTRUCTIONS
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.
4. Check again to make sure the electrical supply is turned “OFF”
to the water heater. Then unplug the water heater (cord set)
or disconnect the electrical supply connection from the water
heater junction box.
FIGURE 5.
5. a. 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 6.
b. 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.

from some plumbing 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.
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.
Insulation Blankets
Insulation blankets are available to the general public for external
use on electric water heaters but are not necessary with this
product. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank heaters. Your
water heater meets or exceeds the National Appliance Energy
Conversation Act standards with respect to insulation and standby
loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions below. Failure to follow these
instructions can result in fire, serious personal injury, or death.
•Do not cover the temperature and pressure relief (T & P)
valve with an insulation blanket.
•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 for placement
on the blanket directly over the existing labels.
Facts to Consider About the
Convertible Lower Element
The Upper Element (if a double element model) is a conventional
3800 watt element which only operates at its rated wattage on
240 volts. (See rating plate on the water heater).
The Lower Element of the water heater can be converted from
operation at 3800 watts to 5500 watts on a 240 volt system.
Read and follow water heater warnings and instructions. If after
reading these instructions in this manual, you do not understand
any portion, call Sears Service Center.
FIGURE 7.
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.
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

Before making the conversion to 5500 watts, check the (1) power
supply . . . must be 240 volts, (2) wiring . . . 10 gauge AWG @
Type TW, 60°C or equivalent, and (3) Circuit breakers or fusing
. . .capable of 30 amp loading. Also, the installation must conform
with this manual, local codes and electric utility rules. Failure to
comply can result in DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE.
NOTE: Whether or not the element conversion is made the model
rating plate must be marked. Using a hard point ink pen, check
the appropriate block within the model rating plate, which is
located adjacent to the lower access panel.
Water Piping
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 handicapped. If anyone using hot water in your home
fits into one of these groups or if there is a local code or state
law requiring a certain temperature water at the hot water tap,
then you must take special precautions. In addition to using the
lowest possible temperature setting that satisfies your hot water
needs, a means such as a mixing valve, should be used at the
hot water taps used by these people or at the water heater.
Mixing valves are available at plumbing supply or hardware
stores. Follow manufacturers instructions for installation of the
valves. Before changing the factory setting on the thermostat,
read the “Temperature Regulation” section in this manual.
See Figure 8 for mixing valve usage.
Figure 9 shows the attachment of the water piping to the water
heater. The water heater is equipped with 3/4” water connections.
FIGURE 8.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc... in the cold water supply; means
must be provided to control thermal expansion. Contact the local
utility or Sears Service Center on how to control this situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water inlet connection.
Do not solder the water supply lines directly to the cold
water inlet. It will harm the dip tube and damage the tank.

10
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.
1. Look at the top cover of the water heater. The hot 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” threaded nipple. Using
flexible connectors, connect the hot water pipe to the hot
water outlet of the water heater.
2. Look at the top cover of the water heater. The cold water inlet
is marked cold. Put two or three turns of teflon tape around
the threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4” threaded nipple. Using flexible
connectors, connect the cold water pipe to the cold water
inlet of the water heater.
NOTE: Your water heater is insulated to minimize heat loss
from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.

FIGURE 9.
T & P Valve and Pipe Insulation
Remove insulation for T & P valve and pipe connections from
carton.
Fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top cover
of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation
does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
FIGURE 9A.
Temperature-Pressure Relief Valve
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 • 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-pressure relief valve must be installed directly
into the fitting of the water heater designed for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 inches (153 mm) above, or at
any distance below the structural floor. Be certain that no contact
