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
A
WARNING
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 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.
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. 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 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 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.
é
Read instruction manual before
installing, using or servicing
water heater.
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.
