Tank (Sediment) Cleaning
Sediment build-up on the tank bottom may create varying
amounts of noise, and if left: in the tank will cause premature
tank fiiilure. 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 sedi
ment deposits. This may be ordered from the Sears Service
Center. For ordering, refer to the “Repair Parts" section.
Venting System Inspection
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 com
bustion and ventilation air flow must not be obstructed.
• Damage or deterioration which could cause improper vent
ing or leakage of combustion products.
• Rusted flakes around top of water heater,
A WARNING
Chemical vapor corrosion of the flue and vent system may
occur if air for combustion contains certain chemical vapors.
Spray can propellants, cleaning solvents, refngerator and air
conditioner refri^rants, swimming pool chemicals, calcium
and sodium chloride, waxes, bleach, and process diemicals are
typical compounds which are potentially corrosive.
AWARNING
ObstnK^ or deteriorated vent systems may present a serious
health risk or asphyxiation.

escape of dangerous flue gasses which could cause deadly
asphyxiation.
