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ow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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 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ue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oodedwaterheaterwill
create dangerous conditions which can cause DEATH, SERIOUS
BODILYINJURY,ORPROPERTYDAMAGE.Contactaqualiedinstaller
orserviceagencytoreplaceaooded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amecharacteristics
and ignition sequences. This can be done by removing the Outer Door
and viewing the main burner operation through the Viewport on the
Inner Door, see Figure 1. The main burner should provide complete
combustion of gas, ignite rapidly, give reasonably quiet operation, and
causenoexcessiveameliftingfromtheburnerports.Iftheproperame
characteristicsarenotevident(seeFigure27),makesurethattheow
of combustion and ventilation air is not blocked.
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, see Figure 27.
PERIODIC MAINTENANCE
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recausingdeath,seriousinjury,orpropertydamage.
FIGURE 27.
BURNER CLEANING
In the event your burner or burner air openings require cleaning, turn
theblowerswitchtothe“OFF”positionandallowtheburnertocool.
Call a 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.
INSTALLEDINSUITABLEAREA:Toinsuresufcientventilation
and combustion air supply, proper clearances from the water heater
mustbemaintained.See“LocatingtheNewWaterHeater”section.
