INTRODUCTION Thank You for purchasing a Sears water heater. Properly installed and maintained, it should give you years of trouble free service. 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.

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 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. 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.
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) 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.
Wiring The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperaturepressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.
c. Flexible metal conduit or flexible metallic tubing shall be permitted for grounding if all the following conditions are met: • The length in any ground return path does not exceed 6 feet. • The circuit conductors contained therein are protected by overcurrent devices rated at 20 amperes or less. • The conduit or tubing is terminated in fittings approved for grounding.
SERVICE AND ADJUSTMENT Temperature Regulation Temperature Settings NOTE: Water temperature range of 120°—140°F (49°-60°C) recommended by most dishwasher manufacturers. TABLE 1: WATER TEMPERATURES 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.
Anode Rod Inspection FIGURE 28B. 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. 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.
NOTE: If the water heater is going to be shut down and drained for an extended period, the drain valve should be left open with hose connected allowing water to terminate to an adequate drain. 6. Close the drain valve, refill the tank, and restart the heater as directed in this manual. NOTE: Some of the terminals may require straight-in wiring through an eye-opening. If wires are now looped, recut and strip wire 3/8” to a straight length and insert. 8. Put plastic terminal cover back in place. 9.
FIGURE 36. 8. Clean the area around the element opening. Remove any sediment from or around the element opening, inside the tank. 9. If you are cleaning the element you have removed, do so by scraping or soaking in vinegar or a de-liming solution. 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. Remove the screw securing the access panel, then remove the panel. FIGURE 33.
Drain Valve Washer Replacement 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. 14. Check element for water leaks. If leakage occurs, tighten element or repeat steps 2 and 3, remove element and reposition gasket. Then repeat steps 10 through 14. 15.
TROUBLESHOOTING Start Up Conditions NOTE: Expansion tanks are pre-charged with a 40 psi air charge. If the inlet water pressure is higher than 40 psi, the expansion tank’s air pressure must be adjusted to match that pressure, but must not be higher than 80 psi. THERMAL EXPANSION As water is heated, it expands (thermal expansion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion.
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.
2. 3. 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. 8. 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.
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. C.
