Service and Adjustment
Tank (Sediment) Cleaning
Burner Inspection
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 vent-
ing orleakage 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 I
escape of dangerous flue gasses which could cause deadly I
asphyxiation. /
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 clean or replace the flue and venting|
before resuming operation of the water heater, |
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 BODILY INJURY, OR PROPERTY
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 (f'-_) to the "OFF" osition,
P
depressing slightly.
NOTE: The knob cannot be turned from "PILOT" to "OFF"
unless knob is depressed slighdy. 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.
