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

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. 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 flame lifting from the burner

ports. If the proper flame characteristics are not evident, see Figure

22, make sure that the flow 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 22.

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 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.
