Service and Adjustment

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 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 sedi­
ment deposits. This may be ordered from the Sears Service
Center. For ordering, refer to the “Parts Order List” 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 venting

or leakage of combustion products.

• Rusted flakes around top of water heater.

AWARNING

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.

AWARNING

Obstructed or deteriorated vent systems may present a serious
health risk or asphyxiation.

AWARNING

Be sure the vent piping is properly connected to prevent
escape of dangerous flue gasses which could cause deadly
asph^iation.

_______________ AWARNING_________________

If after inspection of the vent system you found sooting or
deterioration, something is wrong. Call the local gas utility to
correct the problem and dean or replace the flue and venting
before resuming operation of tiie water heater.

impair proper combustion.

AWARNING
