Contaminated Air

INSTALLATION CONSIDERATIONS

Contaminated Air

Carefully review the warnings concerning contaminated combustion and ventilation air in the instruction manual that came with the water heater. Combustion air that is contaminated can greatly diminish the life span of the water heater and water heater components such as burners, igniters, flue baffles and vent system components. Propellants of aerosol sprays, beauty shop supplies, water softener chemicals and chemicals used in dry cleaning processes that are present in the combustion, ventilation or ambient air can cause such damage.

Vapors from volatile compounds such as solvents, cleaners, chlorine based chemicals and refrigerants in addition to being highly flammable in many cases, can also react to form highly corrosive substances such as hydrochloric acid inside the water heater’s combustion chamber. The results can be hazardous and cause product failure.

Contaminated Air Causes Aggressive Corrosion of Water Heater Components

(Burners, Igniters, Flue Baffles, Vent System, Sheet Metal Parts)

CLEARANCES (WATER HEATER)

A 24-inch clearance for all serviceable parts is recommended. See also Figure 5 and Table 2. You may also refer to the instruction manual or to the label on the water heater for clearances applicable to your specific model.
