Sediment Traps Water heaters covered in this manual have been tested and approved for installation at elevations up to 2,000 feet (610 m) above sea level. For installation above 2,000 feet (610 m), the water heater’s Btu input should be reduced at the rate of 4 percent for each 1,000 feet (305 m) above sea level which requires replacement of the burner orifice in accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local gas supplier for further information.
OPERATING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which is lighted by a piezoelectric igniter. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
Temperature Regulation The thermostat is adjusted to the pilot position when it is shipped from the factory. Water temperature can be regulated by moving the temperature dial to the preferred setting. The preferred starting point is 120°F at the “HOT” setting. Align the knob with the desired water temperature as shown in Figure 22. There is a hot water scald potential if the thermostat is set too high. NOTE: Temperatures shown on the gas control valve/ thermostat are approximates.
Operating the Temperature Control System Water Temperature Adjustment Status Light Codes The water temperature setting can be adjusted from 55°F to 155°F. Turn the Gas Control/Temperature Knob to the desired setting/temperature. See Figure 22 on page 20. Normal Flashes: NOTE: The temperatures indicated are approximates. actual temperature of the heated water may vary. The • 0 Flashes Indicates Control Off/Pilot Out. • 1 Flash Indicates Normal Operation.
SERVICE AND ADJUSTMENT Vent System Inspection Burner Inspection Flood damage to a water heater may not be readily visible or immediately detectable. However, over a period of time a flooded water heater will create dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Contact a Sears Service Center to replace a flooded water heater. Do not attempt to repair the unit! It must be replaced! At least once a year, a visual inspection should be made of the main burner.
Removing the Burner Door Assembly 1. Turn off the gas to the water heater at the manual shut-off valve (Figure 2). 2. Turn the gas control/temperature knob to the “OFF” position (Figure 22). 3. Remove the outer door. 4. Remove the two screws (1/4” nut driver) securing the burner door assembly to the combustion chamber (Figure 24). 5. Disconnect the pilot tube (7/16” wrench), the igniter wire from the igniter lead wire, and manifold tube (3/4” wrench) at the gas control valve/thermostat.
6. External Inspection & Cleaning of the Flame Trap Using the old pilot tube as a guide, bend the new pilot tube to match the old one. Make only the bends closest to the pilot before going to the next step. NOTE: Skip this step if you are reusing the existing pilot tube. 7. Although not likely to occur, if debris collects on the flame trap (flame arrestor), use a vacuum, compressed air, or a soft bristle brush to remove it.
Replacing the Burner Door Assembly FLAME-TRAP BRACKET DOOR GASKET FIGURE 30. Piezoelectric Igniter System 1. The piezoelectric igniter system consists of the igniter button, electrode, and wire. The pilot is ignited by an electric spark generated when the igniter button is pressed. (See Figure 31.) Use only factory authorized piezoelectric igniter parts for replacement. Check the door gasket for damage or imbedded debris prior to installation.
Removing and Replacing the Gas Control Valve/Thermostat Housekeeping Vacuum around base of water heater for dust, dirt, and lint on a regular basis. Removing the Gas Control Valve/Thermostat: 1. Turn the gas control/temperature knob to the “OFF” position (Figure 22). 2. Turn off the gas at the manual shut-off valve on the gas supply pipe (Figure 2). 3. Drain the water heater.

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. The anode rod should be checked after a maximum of three years of use, then annually until the condition of the anode rod dictates the replacement of it. NOTE: Artificially softened water requires the anode rod to be inspected annually.
TROUBLESHOOTING GUIDE Start Up Conditions 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. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty.
