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)
