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owmustnotbeobstructed.
• Damageordeteriorationwhichcouldcauseimproperventing
or leakage of combustion products.
• Rustedakesaroundtopofwaterheater.
Be sure the vent piping is properly connected to prevent
escapeofdangerousuegasseswhichcouldcausedeadly
asphyxiation.
Obstructions and deteriorated vent systems may present serious
health risk or asphyxiation.
Chemicalvaporcorrosionofthe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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 flooded water heater will 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!
At least once a year a visual inspection should be made of
the main burner and pilot burner, see Figure 24.
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 fire 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 clockwise ( )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.
