You should check for sooting. Soot is not normal and will impair
proper combustion.

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
Fire or Explosion Hazard
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.
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.
Read instruction manual before

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! tt must be replaced!
