Rigid pipe constructed of 2.2mm (minimum)
thick 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.
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 than 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 230°F/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.
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 eciency of a unit's performance and the
operation of its venting system.
