SERVICE AND ADJUSTMENT
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.
Vent System Inspection
Carbon Monoxide and Fire Hazard
• 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 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.
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 airflow must not be obstructed.
• Damage or deterioration which could cause improper venting
or leakage of combustion products.
• Rusted flakes around top of water heater.
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.
Flood damage to a water heater may not be readily visible or
immediately detectable. Flowever, 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 29.
You should check for sooting,
proper combustion. Soot is not normal and will impair
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
A
DANGER
Fire or Explosion Hazard
Failure to properly reseal the combustion chamber will
disable the flammable vapor ignition resistance feature
of this water heater, which could result in death or serious
injury.
Contact your local Sears Service Center
for assistance.

if?
In the event your burner needs cleaning, follow these instructions:
If inspection of the burner shows that cleaning is required, turn the
gas control knob clockwise ( o ) to the “OFF” position, depressing
slightly.
NOTE: The knob cannot be turned from “PILOT” to “OFF” unless
knob is depressed slightly. DO NOT FORCE.
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.
