—OR —

•isolate boiler and provide outside combustion air. See national, provincial or local codes for further information.

Table 1  Corrosive or destructive contaminants and likely locations

Products to avoid

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

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

Adhesives used to fasten building products and other similar products

Airborne particulates (drywall dust, fiberglass particles, road or gravel dust, lint, etc.)

Areas likely to have contaminants

Dry cleaning/laundry areas and establishments

Swimming pools

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

Garages with workshops

Buildings under construction (where air is contaminated with particulates)

CONSTRUCTION DUST HAZARD — Airborne particulates, such as drywall dust or fiberglass dust, will cause blockage of the CGi burners, resulting in carbon monoxide production, a fire hazard, or building freeze damage. If the boiler is operated during construction, you must isolate the boiler to provide clean air for combustion. If you are unable to ensure uncontaminated air in the boiler vicinity at all times, you must inspect the boiler at least once weekly. When inspecting, clean the burners if necessary using the procedure given on page 45. Failure to follow these guidelines could result in severe personal injury, death or substantial property damage.
