INSTALLATION INSTRUCTIONS
Removing the Old Water Heater
1. Turn “OFF” electrical supply to the water heater.
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 fl ow 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 4.
5a. 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 temperature­pressure 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.
3. Attach a hose to the water heater drain valve and put the other
end in a fl oor 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.
FIGURE 3.
FIGURE 5a.
5b. 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.

FIGURE 5b.
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
• Sensors mounted in the metal drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.
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 fl ow 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 fl ow of water will not cause damage to the structure. When such locations cannot be avoided, a suitable metal 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 metal drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped metal drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the metal drain pan that trigger an alarm or turn
off the incoming water to the water heater when leakage is detected.
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 fi re, 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.
8
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 infi rm, or physically/mentally handicapped. If anyone using hot water in your home fi ts 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 satisfi es 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.
Before making the conversion to 5500 watts, make sure that the (1) power supply is 240 volts, (2) the wiring is 10 gauge AWG @ Type TW, 60°C or equivalent, and (3) the circuit breakers or fusing are 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.
FIGURE 6.
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
See Figure 7 (below) for mixing valve usage.
FIGURE 7.
Figure 8 shows the attachment of the water piping to the water heater. The water heater is equipped with 3/4” water connections.
If a water heater is installed in a closed water supply system; such as one having a back-fl ow 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.

water fi ttings, 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 tefl on tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” threaded nipple. Using fl exible connectors, connect the hot water pipe to the hot water outlet of the water heater.
valve. See Figure 9. Apply gentle pressure to the insulation to ensure that it is fully seated on the T&P Relief Valve. Once seated, secure the insulation with duct tape, electrical tape, or equivalent. IMPORTANT: The insulation and tape must not block the discharge opening or hinder access to the manual relief lever (Figure 9). Ensure a discharge pipe is installed into the T&P valve discharge opening per the instructions in this manual.
4. Locate the hot water (outlet) & cold water (inlet) pipes to the water heater.
2. Look at the top cover of the water heater. The cold water inlet is marked cold. Put two or three turns of tefl on tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” threaded nipple. Using fl exible 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.
5. Locate the slit running the length of a section of pipe insulation.
6. Spread the slit open and slip the insulation over the cold water (inlet) pipe. Apply gentle pressure along the length of the insulation to ensure that it is fully seated around the pipe. Also, ensure that the base of the insulation is fl ush with the water heater. Once seated, secure the insulation with duct tape, electrical tape, or equivalent.
7. Repeat steps 5 and 6 for the hot water (outlet) pipe.
8. Add additional sections of pipe insulation as needed.
