IMPORTANT INFORMATION ABOUT THIS WATER HEATER
This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident. The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the following checklist and make any required installation upgrades or changes.
Questions? Contact Sears at 1-800-4-MY-HOME (1-800-469-4663).
Installation Checklist
Water Heater Location
Water heater location is important and can affect system performance. Please check the following:
□Installation area free of corrosive elements and flammable materials.
□Centrally located with the water piping system (For new installations). Located as close to the gas piping and vent pipe system as possible.
□Located indoors and in a vertical position. Protected from freezing temperatures.
□ Proper clearances from combustible surfaces maintained and not installed directly on a carpeted floor.
□Provisions made to protect the area from water damage. Metal drain pan installed and piped to an adequate drain.
□Sufficient room to service the water heater. See Clearances and Accessibility section of this manual.
□Water heater not located near an air moving device.
□Is the installed environment dirty (excessive amounts of lint, dirt, dust, etc.)? If so, the base-ring filter located on the bottom of the water heater will need to be cleaned periodically. Refer to the “Maintenance of your Water Heater” section of this manual for information on cleaning the base-ring filter.
Combustion Air Supply and Ventilation
Check for sufficient combustion air supply. Insufficient air for the combustion of gas will result in the flame becoming “lazy”, thereby allowing heat to build up in the combustion chamber. This excessive heat will cause a thermal switch on the door assembly to trip. Is the water heater installed in a closet or other small, enclosed space? If so:
□Fresh air openings must be sized correctly with consideration given to the blocking effect of louvers and grilles.
□Ductwork must be the same cross-sectional area as the openings.
Vent Pipe System
Check for proper drafting at the water heater draft hood. Refer to the “Checking the Draft” section of this manual for the test procedure. If the procedure shows insufficient draft is present, please check the following:
□Draft hood properly installed.
□Vent connectors securely fastened with screws and supported properly to maintain six inch clearance.
□Vent connector made of approved material and sized
□
□
Are there openings for make-up air to enter and exit the room/area?
Are the openings of sufficient size? Remember, if there are other gas-fired or air-consuming appliances in the same room, you need more make-up air. Refer to the “Installation Instructions” and “Combustion Air Supply and Ventilation” sections for specific requirements.
□Make sure that fresh air is not taken from areas that contain negative pressure producing devices such as exhaust fans, dryers, fireplaces, etc.
□Is there a furnace/air handler in the same room space as the water heater? If so, has a return air duct system been attached that exits the room? If so, check for leaks on the air duct system. If no air duct system is present, correct immediately by contacting a local Heating, Ventilation, AirConditioning & Refrigeration (HVAC-R) authorized service provider.
□Use a fresh air supply that is free of corrosive elements and flammable vapors.

3.Check again to make sure the gas supply is “OFF” to the water heater. Then disconnect the gas supply connection from the gas control valve.
4.Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. (See Figures 2 and 5.) Open the water heater drain valve. 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.

5.Disconnect the vent pipe from the draft hood where it connects to the water heater. In most installations the vent pipe can be lifted off after any screw or other attached devices are removed. Dispose of the draft hood. The new water heater has a draft hood which must be used for proper operation.
6.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. See Figure 6. This will avoid cutting off 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.
If you have galvanized pipes 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. See Figure 7. 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. 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.
