1d Prepare boiler location — contamination
Please review the following information on potential combustion air contamination problems.
Refer to Table 1 for products and areas which may cause contaminated combustion air.
To prevent potential of severe personal injury or death, check for products or areas listed below before installing boiler. If any of these contaminants are found:
•remove contaminants permanently
—OR —
•isolate boiler and provide outside combustion air. See national, provincial or local codes for further information.

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 air supply to provide clean air for combus- tion. Follow the instruction manual guidelines for piping intake air. If you are unable to ensure uncontaminated air in the boiler air intake 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 39. Failure to follow these guidelines could result in severe personal injury, death or substantial property damage.
