General venting

Polypropylene

This product has been approved for use with polypropylene
vent with the manufacturers listed in Table 2D.
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
Flexible polypropylene
For use of flex pipe, it is recommended to have the vent material
in 32°F or higher ambient space before bending at installation.
No bends should be made to greater than 45° and ONLY
installed in vertical or near vertical installations (FIG. 2-8).

approved vent adapters. Discard CPVC
starter piece.
All vent connections MUST be secured by
the vent manufacturer's joint connector
(FIG. 2-9).
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.
Use only the adapters and vent system
listed in Tables 2D and 2E.
mix vent systems of different types or
manufacturers. Failure to comply could
result in severe personal injury, death, or
substantial property damage.
