ventInG sYsteM InspectIon
At least once a year a visual inspection should be made of the venting
system. You should look for:
1. Obstructions which could cause improper venting. The combustion
and ventilation air flow must not be obstructed.
2. Damage or deterioration which could cause improper venting or
leakage of combustion products.
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 after inspection of the vent system you found sooting or
deterioration, something is wrong. Call the local gas utility to correct
the problem and clean or replace the flue and venting before
resuming operation of the water heater.
Burner operatIon and InspectIon
Flood damage to a water heater may not be readily visible or
immediately detectable. However, over a period of time a flooded
perIodIc MaIntenance
water heater will create dangerous conditions which can cause
DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
Contact a qualified installer or service agency 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 the hot surface igniter assembly for proper flame
characteristics and ignition sequences. You should also check for
sooting. Soot is not normal and will impair proper combustion. A visual
inspection of the main burner and HSI igniter assembly should also be
done at least once a year.
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 or burner air openings require cleaning,
turn the on/off switch to the “OFF” position and allow the unit to cool.
Call a qualified service agency to remove and clean the burner and
correct the problem that required the burner to be cleaned.
houseKeepInG
Vacuum around base of water heater for dust, dirt, and lint on a
regular basis.
