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;

• Obsrructions 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 combusdon 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 diemical vapors.
Spray can propellants, deaning solvents, refrigerator and air
conditioner refrigerants, swimming pool chemicals, calcium
and sodium chloride, waxes, bleach, and process chemicals are
typical compounds v^ich are potentially corrosive.

AWARNING

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

AWARNING

Be sure the vent piping is properly connected to prevent

escape of dangerous flue gasses which could cause deadly
asph^ation.

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 the water heater.

Burner Inspection

^____________ AWARNINCT_____________ _

Do not use this appliance if any part of it has been under water.
Immediately call a Sears Service Technician to inspect the
appliance and to replace the gas control or any part of the
burner system which has been under water.

At least once a year a visual inspection should be made of the

main burner and pilot burner. The drawing is for your reference.
You should check for sooting which is not normal and will

impair proper combustion.

AWARNING

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 or explosion causing
DEATH,

SERIOUS

DAMAGE.

Burner Cleaning

In the event your burner needs cleaning, use the following

instructions;
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 £rom “PILOT” to “OFF”

unless knob is depressed slightly. DO NOT FORCE.
Loose deposits on or around the burner can be removed by care­

fully 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 Sears Service Center to remove

and clean the burner and correct the problem that required the

burner to be cleaned.
