Tank (Sediment) Cleaning Burner inspection
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.
Flood damage to a water heater may not be readily visible
or immediately detectable. However, over a period of time
a flooded water heater wilt create dangerous conditions
which can cause DEATH, SERIOUS BODILY INJURY, OR
PROPERTY DAMAGE. Contact a Sears Service Center to
replace a flooded water heater. Do not attempt to repair the
unit! It must be replaced!
Vent System inspection
At least once a year a visual inspection should be made of
the main burner and pilot burner, see Figure 24.
At least once a year a visual inspection should be made of the
venting system. You should look for:
You should check for sooting. Soot is not normal and wilt
impair proper combustion.
Obstructions which could cause improper venting. The
combustion 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.
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 causing death,
serious injury, or property damage.
Carbon Monoxide and Fire Hazard
• Flue gases may escape if vent pipe
is not connected.
• _:¢i?:"
• 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 flue and vent
system can cause serious injury or
death.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.

Be sure the vent piping is properly connected to prevent
escape of dangerous flue gasses which could cause deadly
asphyxiation.
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
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,
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 flue and venting
before resuming operation of the water heater.
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 clockwise ( f_ ) to the "OFF" position,
depressing slightly.
NOTE: The knob cannot be turned from "PILOT" to "OFF"
unless knob is depressed slightly. DO NOT FORCE.
Loose deposits on or around the burner can be removed by
carefully 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.
