CONTAMINATED AIR

= RUST

CHIPS

Along with adequate make-up air, the quality of the air is important. Contaminants in combustion air can lead to premature heater failure. Vapors from bleaches, soaps, salts, etc. are drawn into the combustion chamber with the make-up air and, once fired, mix with water vapor in the gasses to form extremely corrosive hydrochloric or hydrofluoric acid and other corrosive by-products. Dust drawn in may build up on the blower or clog the main burner ports. Also, be certain to examine the exterior area around the air intake of a direct vent installation for the contaminants.

FLAMMABLE ITEMS

Flammable items or pressurized containers or any other potentially hazardous articles must never be placed on or adjacent to the heater. Open containers of flammable material should not be stored or used in the same room with the heater or in the area of the exterior air intake of a direct vent installation. Direct venting does not eliminate the need to remove flammable or corrosives from the area surrounding the heater.
