Venting and combustion airIV
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
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.
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.
