PVC pipes are commonly used for venting AERCO condensing water heaters and boilers. An environmentally safe and engineered alternative is PolyPro, 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. 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 an engineered corrosion-free, condensation management system.
Ideal for high efficiency condensing boilers, and instantaneous hot water heaters. Listed by Intertek to the ULCS636 standard in Canada, and is rated as a Class IIA, IIB, and IIC vent system. PolyPro’s walls expand and contract with weather and temperature changes so there is no flexing or cracking in the venting. The terminations remain ice free in freezing weather and the interior of the 90° elbows are 88° to prevent standing condensation. The PolyPro product line has a higher sustained operating temperatures than PVC/CPVC and is corrosion resistant.
Lightweight and easy to install in less time, PolyPro does not require flammable, messy or harmful glues, cements or solvent at connections, meaning no glue curing time during installation. A variety of supports are available to make installation easier. The viton gasketed connections also allow for removal and replacement of components.
