Kenmore 153.330652 Tank Sediment Cleaning, Carbon Monoxide and Fire Ha rd, Burner Inspection

Tank (Sediment) Cleaning

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.

Vent System Inspection

Carbon Monoxide and Fire Ha_rd

•Fiue gases may esca_ if vent pipe is not connected,

•Be ale_ for obstructed, sooted or deteriorated vent system to avoid serious injury or death,

,Do not store corrosive chemicals in the vicinity of ,water heater°

•Chemi_ corrosion of flue and vent system _n cause sedous, injury of death,

Breathing carbon monoxide can _ase brain damage or death, Aiways read and understand instructionmanual

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 when inspecting the vent system you find sooting or deterioration, something is wrong. Call the 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 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. See Figure 23.
