It is strongly suggested that this new water heater be professionally installed, contact the local Sears Service Center or any Sears store. They will arrange for prompt, quality installation by Sears authorized contractors.
MATERIALS AND BASIC TOOLS NEEDED Materials Needed To simplify the installation Sears has available the installation parts shown below. You may or may not need all of these materials, depending on your type of installation. WATER HEATER INSTALLATION KIT WITH FLEXIBLE CONNECTORS FOR 3/4” OR 1/2” THREADED OR COPPER PLUMBING. E X PA N S I O N TA N K S F O R T H E R M A L EXPANSION CONDITIONS AVAILABLE IN 2 GALLONS , AND 5 GALLONS capacity through local Sears store or Service Center.
INSTALLATION INSTRUCTIONS Removing the Old 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 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 4. 5a.
• 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. 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.
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.
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.
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.
Converting the Lower Element Necessary element conversion parts are located in a small bag contained within the electrical junction box on top of the water heater. These instructions only cover the conversion of the convertible element, read this entire manual before attempting to install or operate the water heater. The water heater is factory set to operate at 3800 watts. The lower element can be converted to operate at 5500 watts.
8. Failure to tighten terminal screws can cause a fire which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. FIGURE 16. 5. Tighten terminals 2 and 3 to ensure proper electrical connection. Remove the screws from terminal 2 of the element, and move the looped end of the wire aside. 9. Replace terminal cover on thermostat making sure that the locking tabs on the terminal cover are in place. FIGURE 17. 6. The buss bar is labeled 5500 W.
11. Replace the access panel. FIGURE 21. 12. Complete wiring to the water heater, or if completed, turn “ON” electric power to the water heater after filling the tank with water. If wiring from your fuse box or circuit breaker box was aluminum for your old water heater, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the water heater made by a competent electrician. Contact your Sears salesperson to arrange for a professional electrician. 1.
5. Wiring Diagrams (see “Wiring Diagrams” section) have been supplied showing the two most common types of connections between the water heater and the power supply. You can easily see which type connection you have by removing the junction box cover on top of the water heater. 6. Use wire nuts and connect the power supply wiring to the wires inside the water heater’s junction box. 7. The water heater must be electrically “grounded” by the installer.

SERVICE AND ADJUSTMENT Temperature Regulation The lower thermostat is factory set at a position which approximates 120°F (49°C), and is adjustable if a different water temperature is desired. Read all warnings in this manual and on the water heating before proceeding. 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.
Temperature-Pressure Relief Valve Operation The upper and lower thermostats are adjustable if a different water temperature is desired. Read all warnings in the “TemperatureRegulation” section before proceeding. The temperature-pressure relief valve must be manually operated at least once a year. 1. Turn “OFF” the electric power to the water heater at the junction box. The temperature-pressure relief valve must be manually operated at least once a year.
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. Turn “OFF” the electrical power to the water heater at the junction box. 2. Remove the access panel and the insulation cap with handle. 3. Lift out the tab as shown below to unclip the terminal cover from the thermostat. The terminal cover can now be removed from the thermostat. 1.
4. Remove the two screws securing the access panel, and remove panel. FIGURE 33. 5. Remove the insulation cap with handle. 1. Before beginning turn “OFF” the electric power supply to the water heater. FIGURE 30. 2. Turn off the water supply to the water heater at the water Shut-off valve or water meter. FIGURE 34. 6. Lift out the tab as shown to unclip the terminal cover from the thermostat. The terminal cover can now be removed from the thermostat. FIGURE 31. 3.
8. Clean the area around the element opening. Remove any sediment from or around the element opening, inside the tank. Never use this water heater unless it is completely full of water. To prevent damage to the tank and heating element, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” power. 9. If you are cleaning the element you have removed, do so by scraping or soaking in vinegar or a de-liming solution. 14. Check element for water leaks.
18. Replace access panel. • Follow “Draining” instructions. See “Draining” section. 19. Turn “ON” electric power to water heater. • Turning counter clockwise, remove the hex cap below the screw handle. • Remove the washer and put the new one in place. • Screw the handle and cap assembly back into the drain valve and retighten using a wrench. DO NOT OVER TIGHTEN. • Follow “Filling the Water Heater” instructions in the “Installation Instructions” section. • Check for leaks. FIGURE 41.
TROUBLESHOOTING Start Up Conditions THERMAL EXPANSION 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.
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. upper and lower thermostats.
NOT ENOUGH OR NO HOT WATER 1. 7. 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. If you had experienced very hot water and now no hot water, the problem may be due to the high temperature shut off system.
LEAKAGE CHECKPOINTS Never use this water heater unless it is completely full of water. To prevent damage to the tank and heating element, the tank must be filled with water. The water must flow from the hot water faucet before turning “ON” power. A *Condensation may be seen on pipes in humid weather or pipe connections may be leaking. B Small amounts of water from the temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area.
