DuraVent PolyPro 90 Degree Elbow: turns an indoor vent from horizontal to vertical
The DuraVent PolyPro 90 Degree Elbow is a gray elbow that turns an indoor vent, such as from a ceiling run upward into a vertical run. Its inside bend is slightly less than a right angle. That lets condensate, the water that collects from the exhaust, run back instead of sitting in the elbow. One locking clamp is included. Choose a 2, 3, 4, 5, 6, or 8 inch size on this page to match the vent. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
The joints push together, with the narrow end sliding into the wider end over a rubber gasket. The ends overlap by 2 inches. A locking clamp comes on the wider end of each pipe and fitting to secure each exhaust joint. In the USA, the appliance maker must list PolyPro for that appliance, and its venting instructions govern the setup. In Canada, DuraVent lists PolyPro as a vent system on its own.
