SERVICE AND MAINTENANCE

Tank (Sediment) Cleaning

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

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.

•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.

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.

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 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 50.

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.

If improper flame characteristics are not evident, check for accumulation of lint or other foreign material that restricts or blocks the air openings in the heater or burner. Also check Combustion Air and Ventilation Requirements.

Burner Cleaning

NOTE: Burner assembly must be handled carefully to avoid damaging the hot surface ignitor.

In the event your burner needs cleaning, following these instructions:

If inspection of the burner shows that cleaning is required, turn the “ON/OFF” rocker switch located on the control box to “OFF” position and allow the burner to cool.

Loose deposits on or around the burner can be removed by carefully using the hose of a vacuum cleaner inserted through the access door of the water heater. If the burner needs to be removed for additional cleaning, call the local gas utility or qualified service agent to remove and clean the burner with a soft brush. Clean main burner orifice with a suitable soft material. Correct the problem that requires the burner to be cleaned.
