SERVICE AND MAINTENANCE Tank (Sediment) Cleaning Burner Inspection Sediment build-up on the tank bottom may create varying amount of noise, if left in the tank will cause permanent tank failure. In some water areas, sediment can be removed by draining off approximately one gallon of water each month. Vent System Inspection • Flue gases may escape if vent pipe is not connected. • Be alert for obstructed, sooted or deteriorated vent system to avoid serious injury or death. • Do not store corrosive chemicals in vicinity of water heater. • Chemical corrosion of flue and vent system can cause serious injury or death 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 the Maytag dealer from whom the appliance was purchased or call Maytag Customer Service at 1-800-788-8899 for an authorized servicer 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 and pilot burner, see Figure 24. You should check for sooting. Soot is not normal and will impair proper combustion. Soot build-up indicates a problem that requires correction before further use. Turn "OFF" gas to water heater and leave off until repairs are made, because failure to correct the cause of the sooting can result in a fire causing death, serious injury, or property damage. At least once a year a visual inspection should be made of the venting system. You should look for: • Obstructions which could cause improper venting. The combustion and ventilation air flow must not be obstructed. FIGURE 24. Burner Cleaning • Damage or deterioration which could cause improper venting or leakage of combustion products. • Rusted flakes around top of water heater. Be sure the vent piping is properly connected to prevent escape of dangerous flue gasses which could cause deadly asphyxiation. Obstructions and deteriorated vent systems may present serious health risk or asphyxiation. Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical compounds which are potentially corrosive. In the event your burner needs cleaning, following these instructions: If after inspection of the vent system you found sooting or deterioration, something is wrong. Call Maytag Customer Service at 1-800-788-8899 for an authorized servicer or your local gas supplier to correct the problem and clean or replace the flue and venting before resuming operation of the water heater. If inspection of the burner shows that cleaning is required, turn the gas control knob clockwise ( ) to the "OFF" position, depressing slightly. NOTE: The knob cannot be turned from "PILOT" to "OFF" unless knob is depressed slightly. DO NOT FORCE. 21
