PolyPro pipes are used for venting water heaters, condensing boilers and warm air furnaces. PolyPro is an environmentally safe and engineered alternative, for condensing gas appliances. Engineered for venting, it is 100% recyclable, and contains no toxic or carcinogenic materials, chlorides, or heavy metals. PolyPro does not release hazardous gases during combustion, and has been used safely throughout Europe for over 20 years. 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.

PolyPro is a polypropylene vent pipe for use with ANSI Category II and IV gas-burning appliances, including highefficiency water heaters, condensing boilers and warm air furnaces. Poly Pro 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 230°F / 110°C, and a maximum positive pressure of 15 in-w.c.
