APPENDIX A

INSIDECOMBUSTIONAIRCONTAMINATION:

All heaters experience some condensation during start-up.

The condensate from flue gas is slightly acidic. In most cases the pH level is not harmful to vents or drains. When combustion air is contaminated by vapors from products in areas listed below, the acidic levels in the condensate increase. Higher acidic levels attack many materials, including stainless steel commonly used in high efficiency systems.

The heater can use special corrosion-resistant nonmetallic intake vent material. You may, however, choose to use outside combustion air for one or more of these reasons:

installation is in an area containing contaminants listed below which will induce acidic condensation.

you want to reduce infiltration into your building through openings around windows and doors.

you are using AL29-4C stainless steel vent pipe, which is more corrosion-resistant than standard metallic vent pipe. In extremely contaminated area, this may also experience deterioration.

Products causing contaminated combustion air:

spray cans containing chloro/fluorocarbons

permanent wave solutions

chlorinated waxes/cleaners

chlorine-based swimming pool chemicals

calcium chloride used for thawing

sodium chloride used for water softening

refrigerant leaks

paint or varnish removers

hydrochloric acid/muriatic acid

cements and glues

antistatic fabric softeners used in clothes dryers

chloride-type bleaches, detergents, and cleaning solvents found in household laundry rooms

adhesives used to fasten building products

... and other similar products.

Areas causing contaminated combustion air:

dry cleaning/laundry areas and establishments

metal fabrication plants

beauty shops

refrigeration repair shops

photo processing plants

auto body shops

plastic manufacturing plants

furniture refinishing areas and establishments

new building construction

remodeling areas.

Check for areas and products as listed above before installing heater. If found:

remove products permanently, OR

provide outdoor combustion air.
