Service and Adjustment
Draft Hood Operation
Check draft hood operation by performing a worst case depres-
surization of the building. With all doors and windows closed,
and with all air handling equipment and exhaust fans operating,
such furnaces, clothes dryers, range hoods and bathroom fans, a
match flame should still be drawn into the draft hood of the
water heater with its burner firing. If the flame is not drawn
toward the draft hood, shut off"the water heater and make neces-
sary air supply changes to correct.
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.
Burner Inspection
AWARNING
Flood damage to a water heater may not be readily visible
or immediately detectible. However, over a period of time
a flooded water heater will create dangerous conditions
which can cause DEATH, SERIOUS BODILY INJURY,OR
PROPERTY DAMAGE. Call a Sears Service Technicianor
contractor 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 and pilot burner. The drawing is for your reference.
You should check for sooting which is not normal and will
impair proper combustion.

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

fbr additional cleaning, call the Sears Service Center to remove
and clean the burner and correct the problem that required the
burner to be cleaned.
