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? Installation Contact Sears at 1-800-4-MY-HOME (1-800-469-4663). Checklist Water Heater Location Water heater location is important and can performance.
Removing the Old Water Heater (_ 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 O 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 MANUAL GAS SHUT-OFFVALVE--_ any person.
Location I area of the water heater, leave the area immediately and call the fire department from a neighbor's home. Do not attempt to clean the spill until all ignition sources have been extinguished. Requirements Carbon Monoxide Poisoning Hazard Fire or Explosion Do not install in a mobile home. Hazard • Read instruction manual before installing, using or servicing water heater. Doing so can result in carbon monoxide poisoning and death. • Improper use may result in fire or explosion.
Property use on gas water heaters are not necessary with Kenmore products. The purpose of an insulation blanket is to reduce the standby heat toss encountered with storage tank heaters. Your Kenmore water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary. Damage Hazard • AJl water heaters eventuafly leak • Do not install without adequate drainage.
-_ Tr- BACK SIDES S°ESllF IH TOP -VIEW Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open when the water heater is in use. II _,_VEHT l To ensure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping. Check all water piping and connections for leaks. Repair as needed. FIGURE 10.
Gas Pressure the fuel is not spilled in the area of the water heater installation, or any source of ignition. If the fuel is spilled while purging the piping system of air follow the "WHAT TO DO IF YOU SMELL GAS" instructions on the cover of this manual. LP Gas Only Explosion Hazard • Gas leaks can not always be detected by smell. • Gas suppliers recommend that you use a gas detector approved by UL or CSA. Explosion • For more information, contact your gas supplier.
TABLE 3 Carbon Monoxide Warning Follow all the local and state codes or, in the absence of local and state codes, the "National Fuel Gas Code", ANSI Z223.1 (NFPA 54)- current edition to properly install vent system. Failure to do so can result in death, explosion, carbon monoxide poisoning.

It is recommended (but not mandatory) that a minimum 12 inches of vertical vent pipe be installed on the draft hood prior to any elbow in the vent system. An unused chimney flue or masonry enclosure may be used as a passageway for the installation of a gas vent (Figure 21 ).
Piping Installation IN A CLOSED _THERMAL Piping, fittings, and valves should be installed according to the installation drawing (Figure 22). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation.

Closed System/Thermal Property For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked "T & P RELIEF VALVE." (See Figure 24). This valve must be design certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22.
Lighting Instructions Read and understand these directions thoroughly before attempting to light or re-light the pilot. Make sure the view port is not missing or damaged. (See Figure 32.) Make sure the tank is completely filled with water before lighting the pilot. Check the rating plate near the gas control valve/thermostat for the correct gas. Do not use this water heater with any gas other than the one listed on the rating plate.

Vent System At least once a year, a visual inspection should be made of the main burner and pilot burner. See Figure 29. Inspection You should check for sooting. Soot is not normal and will impair proper combustion. Carbon Monoxide , . Soot build-up indicates a problem that requires correction before further use.
Anode deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by calling the Sears Service Center for an authorized contractor. At a minimum, the anode(s) should be checked annually after the warranty period.

IGNITER BUTTON MANIFOLD TUBE Replacement parts may be ordered from Sears Parts and Service Centers or by calling 1-800-4-MY-HOME (1-800-469-4663). When ordering replacement parts, always have the following information ready: 1. 2. 3. 4. See 1. & Cleaning 3.
6. Position the new thermocouple through the bottom opening of the manifold component block (Figure 34). Be sure igniter wire is positioned through the small opening of the manifold component block. 7. Re-attach the burner. Note the orientation (Figure 33.) 8.

Replacing the Manifold/Burner Explosion Tighten both manifold control valve/thermostat. Finally, start the thermocouple and turn it all the way in by hand. An additional quarter with a 3/8" open-end wrench will then be sufficient to the lockwasher. When you are finished, connect the wire leads that go to the thermal switch. Assembly 7, Reconnect the igniter wire. 8. Turn gas supply on and refer to the Lighting Instructions. 9.
Testing the Igniter 2. System Turn off the gas to the water heater at the manual gas shut-off valve. Watch the electrode tip while activating the igniter. A visible spark should jump from the electrode. To avoid shock, do not touch the burner or any metal part on the pilot or pilot assembly. If no spark is visible, check the wire connections and make sure the electrode is not broken. Replace the igniter if defective. Dirt and rust on the pilot or electrode tip can prevent the igniter spark.
Start Up Conditions Thermal 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.

if the flame is absent. This unit is also equipped with a thermal switch, designed to shut off the gas supply in the event the water heater has been exposed to flammable vapors (e.g., spilled gasoline), poor combustion caused by a blocked vent or insufficient combustion air. If the thermal switch opens: 1. Check the flame-arrestor for signs of high temperature or black discoloration). See Figure 38.
