Specifications
Applications
PolyPro is a polypropylene vent pipe
for use with ANSI Category II and IV
gas-burning appliances, including high-
eciency water heaters, condensing
boilers and warm air furnaces. PolyPro
is listed by Intertek to the ULC S636
standard in Canada as a Class IIA, IIB
and IIC vent system suitable for exhaust
temperatures up to 23F / 110°C, and a
maximum positive pressure of 15 in-w.c.
Materials and Construction
Rigid pipe constructed of 2.2mm
(minimum) thick polypropylene.
Flex is double-wall polypropylene.
EPDM or optional Viton Gaskets
Clearances
0” clearance to combustibles for exhaust
temperatures up to 194°F / 90°C, and
0” clearance for vertical installations
up to exhaust temperatures of 230°F
/ 110°C and ¼” / 6mm clearance to
combustibles for horizontal installations
at exhaust temperatures up to 230°F /
110°C . PolyPro concentric vent system
components, including concentric
Horizontal Termination and Vertical
Termination, are listed at 0” clearance to
combustibles for exhaust temperatures
up to 230°F / 110°C.
Diameters
2" (60mm), 3" (80mm), 4" (100mm),
5" (130mm), 6" (150mm), and 8" (200mm).

PolyPro
PolyPro and PVC/CPVC: PVC pipes are commonly used for venting
water heaters, condensing boilers and warm air furnaces, yet PVC
was never designed for such use. An environmentally safe and
engineered alternative for condensing gas appliances is PolyPro.
Engineered for venting, it is 100% recyclable; contains no toxic
or carcinogenic materials, chlorides, or heavy metals; and is also
easier and faster to install then PVC, saving the contractor time
and money. PolyPro does not release hazardous gases during
combustion and has been used safely throughout Europe
since the early 1990s. Polypropylene has a higher operating
temperature limit of 23F/110°C (PVC is 149°F/65°C max and
CPVC is 194°F/90°C). PolyPro is engineered with a corrosion-free,
condensation management system.
PolyPro Flex
PolyPro Flex through B Vent as a Chase: Retrot venting for new,
high-eciency appliances. When replacing a mid-eciency
appliance with a new condensing 90+ appliance, you can use the
existing B vent (any brand) as a chase for the new appliance with
PolyPro. The perfect solution for utilizing the B Vent already in
place, use the convenient pull cone to insert double-wall PolyPro
Flex through the B Vent pipe and terminate in either a two pipe or
single pipe system. At the other end is the unique B Vent/PolyPro
Support Cap, allowing for the connection of ex to rigid PolyPro
lengths and elbows to nish the installation.
Terminations
DuraVent’s concentric PolyPro vertical terminations are lab
tested to handle harsh weather and remain icicle free in freezing
temperatures. Air circulation and weather conditions like rain,
wind and ice have the potential to reduce the eciency of a unit's
performance and the operation of its venting system.
