CHEMICAL VAPOR CORROSION
Corrosion of the flue ways and vent system will occur if air for combustion contains certain chemical vapors. Such
corrosion may result in poor combustion and create a risk of asphyxiation, as well as reducing the life of the water heater.
Spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium
and sodium chloride, waxes and process chemicals are corrosive. Products of this sort should not be stored near the
water heater or outside by the air intake (if applicable).

CAUTION
If the building cold water supply has a back-flow preventer, check valve or water meter with check valve
provisions for thermal expansion of water in the hot water system must be provided.
