IV Venting and combustion air

GV boiler must be vented and supplied with combustion and ventilation air as described in GV Series 3 Venting supplements packed in envelope assembly with boiler. Failure to do so will cause severe personal injury or death.

Install vent piping and air piping (if used) per appropriate Vent supplement included in boiler envelope assembly.

Refer to Vent supplement and to manual Section I regarding requirements for:

•vent system

•combustion air openings

•combustion air quality

Use direct vent (sealed combustion) if combustion air quality cannot

be assured to be free of contaminants. Refer to page 13 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.
