GOLD CGs Gas-Fired Water Boiler — Boiler Manual

4 Venting and combustion air

Install vent piping and air piping (if used) per appropriate Venting Supple- ment included in boiler envelope assembly.

Refer to Venting Supplements and to manual Section 1 regarding require- ments for:

•vent system

•combustion air openings

•combustion air quality

CGs Boiler must be vented and supplied with combus- tion and ventilation air as described in Weil-McLain CGs Venting Supplements packed in envelope as- sembly with boiler. Failure to do so will cause severe personal injury or death.

Use direct vent (sealed combustion) if combustion air quality cannot be assured to be free of contaminants.

Refer to page 9 for a list of potential contaminants and locations likely to contain them. Operating the boiler with contaminated air will damage the boiler sections and vent, resulting in possible boiler failure or leakage of flue products, causing severe personal injury, death or substantial property damage.
