WARNING
Asphyxiation Hazard.
All polypropylene vent systems rely on gaskets
for sealing. Ensure gaskets are installed in
each female end of vent pipe or fitting. Failure
to make proper joint connections could
cause products of combustion and/or carbon
monoxide to enter the building, resulting in
severe personal injury, death or substantial
property damage.
1. Concentric terminals listed in Table 8-13 may be
used to terminate air and vent outside building
per Figure 8-14. Both air and vent pipes must
attach to terminal kit.
