Removing and Replacing the Gas Control Valve/Thermostat IMPORTANT: The gas control valve/thermostat valve with a right-hand thread thermocouple. authorized replacement parts. is a standard Use only factory Removing the Gas Valve: 1. Turn the gas control knob on the combination gas control valve/thermostat clockwise to the "OFF" position. NOTE: Depress the dial stop on Robertshaw valves before turning the gas control knob. See Lighting Instructions on the water heater. 2. Turn off the gas at the manual shut-off valve on the gas supply pipe (Figure 3). 3. Drain the water heater. Refer to "Draining" section and follow the procedure. 4. Disconnect the igniter wire from the igniter. NOTE: First remove the igniter from the bracket by depressing front and rear holding tabs and lift. Next remove igniter bracket from the gas valve. Disconnect the thermocouple (right-hand threads), pilot tube, and manifold tube at the gas control valve/thermostat (Figure 25). 5. Refer to "Gas Piping" section and disconnect the ground joint union in the gas piping. Disconnect the remaining pipe from the gas control valve/thermostat. 6. To remove the gas valve, thread a correctly sized pipe into the inlet and use it to turn the gas valve (counterclockwise.) Do not use pipe wrench or equivalent to grip body. Damage may result, causing leaks. Do not insert any sharp objects into the inlet or outlet connections. Damage to the gas valve may result. Replacing the Gas Valve: To replace the gas control valve/thermostat, reassemble in reverse order. When replacing the gas valve, thread a correctly sized pipe into the inlet and use it to turn the gas valve (clockwise.) result. DO NOT OVER TIGHTEN, damage may Be sure to use approved Teflon e tape or pipe joint compound on the gas piping connections and fitting on the back of the gas control valve that screws into tank. Be sure to remove the pilot ferrule nut from the new gas control valve/thermostat. Turn the gas supply on and check for leaks. Test all connections by brushing on an approved noncorrosive leak-detection solution. Bubbles will show a leak. Correct any leak found. Be sure tank is completely filled with water before lighting and activating the water heater.

See Facts to Consider About the Location section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater because they could catch on fire. Anode Rod Inspection Property Damage Hazard - Avoid water heater damage. - Inspection and replacement of anode red required. The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod deteriorates to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water's taste or color. The rod must be maintained to keep the tank in operating condition. 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. 24
