Tank (Sediment) Cleaning
Sediment build-up on the tank bottom may create varying
amount of noise, and if left in the tank will cause permanent 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
sediment deposits. This may be ordered from the Sears Service
Center. For ordering, refer to the
Parts Order List section.
Vent 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
combustion and ventilation air fl ow must not be obstructed.
• Damage or deterioration which could cause improper venting
or leakage of combustion products.
• Rusted fl akes around top of water heater.
Be sure the vent piping is properly connected to prevent
escape of dangerous fl ue gasses which could cause deadly
asphyxiation.
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
Chemical vapor corrosion of the fl ue 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.
If when inspecting the vent system you find sooting or
deterioration, something is wrong. Call the local gas supplier to
correct the problem and clean or replace the fl ue and venting
before resuming operation of the water heater.
Burner Inspection
Flood damage to a water heater may not be readily visible
or immediately detectable. However, over a period of time a
fl ooded water heater will create dangerous conditions
which
can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. Contact a Sears Service Center to replace a fl ooded
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. See Figure 23.
You should check for sooting. Soot is not normal and will impair
proper combustion.
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 fi re causing death, serious
injury, or property damage.

Burner Cleaning
In the event your burner needs cleaning, following these
instructions:
If inspection of the burner shows that cleaning is required, turn the
gas control knob counter-clockwise (
) to the “OFF” position,
depressing slightly.
The burner needs to be removed for cleaning. Call the Sears
Service Center to remove and clean the burner and correct the
problem that required the burner to be cleaned.
SERVICE AND ADJUSTMENT
• Flue gases may escape if vent pipe
is not connected.
• Be alert for obstructed, sooted or
deteriorated vent system to avoid
serious injury or death.
• Do not store corrosive chemicals
in vicinity of water heater.
• Chemical corrosion of fl ue and vent
system can cause serious injury or
death
