Polypropylene
This product has been approved for use with polypropylene
vent with the manufacturers listed in Table 2F.
All terminations must comply with listed options in this manual
and be a single-wall vent offering.
For support and special connections required, see the
manufacturer's instructions. All vent is to conform to standard
diameter and equivalent length requirements established.
When determining equivalent combustion air and vent length
for polypropylene single-wall piping:
• 1 foot of Duravent 4 inch single-wall pipe is equivalent
to 1.6 feet of piping
Use only the adapters and vent system listed in
Tables 2F and 2G. DO NOT mix vent systems
of different types or manufacturers. Failure
to comply could result in severe personal
injury, death, or substantial property damage.
 WARNING
Installations must comply with applicable
national, state, and local codes. For Canadian
installation, polypropylene vent must be listed
as a ULC-S636 approved system.
Installation of a polypropylene vent system
should adhere to the vent manufacturer’s
installation instructions supplied with the
vent system.
Table 2F Polypropylene Vent Pipe and Fittings
 WARNING
Insulation should not be used on
polypropylene venting materials. The use
of insulation will cause increased vent wall
temperatures, which could result in vent pipe
failure.
The installer must use a specific vent starter
adapter at the flue collar connection. The
adapter is supplied by the vent manufacturer
to adapt to its vent system. See Table 2F
for approved vent adapters. Discard CPVC
starter piece.
NOTICE
All vent connections MUST be secured by the
vent manufacturer's joint connector (FIG.
2-4).
