Installation & Operation Manual

Approved PolypropyleneTerminations
Polypropylene
This product has been approved for use with polypropylene
vent with the manufacturers listed in Table 3H.
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 foot 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. 3-3).
Use only the adapters and vent system listed in
Tables 3H and 3I. 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.
⚠
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 3H
for approved vent adapters. Discard CPVC
starter piece.
NOTICE
All vent connections MUST be secured by
the vent manufacturer's joint connector
(FIG. 3-4).
