WARNING WARNING Carbon Monoxide Poisoning Hazard Fire or Explosion Hazard Do not install in a mobile home. • Read instruction manual before installing, using or servicing water heater. Doing so can result in carbon monoxide poisoning and death.
use on gas water heaters are not necessary with Kenmore products. The purpose of an insulation blanket is to reduce the standby heat loss 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.
VENT BACK • 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. • 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.
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. WARNING LP Gas Only WARNING 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. • For more information, contact your gas supplier.

WATER SYSTEM PIPING Piping Installation IN A CLOSED SYSTEM USE A THERMAL EXPANSION TANK COLD WATER SUPPLY TO FIXTURES 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. PRESSURE REDUCING VALVE WITH BYPASS COLD WATER INLET HOT WATER OUTLET COLD WATER INLET VALVE (SHUT-OFF VALVE) The water supply pressure should not exceed 80 psi.
Closed System/Thermal Expansion 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.
OPERATING YOUR WATER HEATER Lighting Instructions WARNING 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.
Checking the Draft Water Temperature Regulation WARNING Water temperature over 125°F (52°C) can cause servere burns instantly resulting in severe injury or death. Burn Hazard Children, the elderly, and the physically or mentally disabled are at highest risk for scald injury. Do not touch vent. Feel water before bathing or showering. Doing so can result in burns. Temperature limiting valves are available.

SERVICE AND ADJUSTMENT Tank (Sediment) Cleaning Burner Inspection Sediment build-up on the tank bottom may create varying amount of noise, and if left in the tank will cause permanent tank failure. In some water areas, you may not be able to drain all sediment deposits by simply draining the tank. In these cases, Mag-Erad (part no. 23600) can be used to help remove the sediment deposits. This may be ordered from the Sears Service Center. For ordering, refer to the “Parts Order List” section.
Housekeeping 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.
operation. The water heater should be drained if being shut down during freezing temperatures. To drain the tank, perform the following steps: If the water heater is going to be shut down for an extended period, the drain valve should be left open. IMPORTANT: Condensation may occur when refilling the tank and should not be confused with a tank leak. 1. Turn off the gas to the water heater at the manual gas shut-off valve. 2. Open a nearby hot water faucet until the water is no longer hot. 3.
MAINTENANCE OF YOUR WATER HEATER Replacement Parts GAS CONTROL VALVE/ THERMOSTAT IMPORTANT: The following maintenance procedures are for the FVIR System components and should be performed by a qualified technician. 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. model, serial, and product number 2. type of gas 3. item number 4.
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. 8. Connect the new pilot tube and tighten the nut securing it to the pilot assembly. IMPORTANT: Keep the pilot orifice in the pilot when making the connection. Do not operate the water heater without the pilot orifice installed. 7. Re-attach the burner. Note the orientation of the burner (Figure 33.) 9.
Replacing the Manifold/Burner Assembly control valve/thermostat. Finally, start the thermocouple nut and turn it all the way in by hand. An additional quarter turn with a 3/8” open-end wrench will then be sufficient to seat the lockwasher. When you are finished, connect the two wire leads that go to the thermal switch. WARNING Explosion Hazard • Tighten both manifold door screws securely. • Remove any fiberglass between gasket and combustion chamber.
Testing the Igniter System 2. Reconnect the gas piping to the gas control valve/ thermostat. NOTE: Use an approved Teflon tape or pipe compound on the gas piping connections. 3. Attach the igniter and bracket to the new gas control valve/ thermostat, clipping it at the back edge of thermostat and snapping it into place. NOTE: Do not use the (pilot) ferrule nut supplied with the new gas control valve/thermostat, unless the existing nut is not usable.
TROUBLESHOOTING GUIDE 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.
drawn toward the draft hood, shut off water heater and make necessary air supply changes to correct. result of four factors which must all be present for the odor to develop: • a concentration of sulfate in the supply water. Condensation • little or no dissolved oxygen in the water. • a sulfate reducing bacteria within the water heater. (This harmless bacteria is non-toxic to humans.) • an excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode.
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 (blue or black discoloration). See Figure 38. 2.
