DuraVent PolyPro Concentric 90 Degree Elbow: turns a horizontal vent run upward
The DuraVent PolyPro Concentric 90 Degree Elbow is an elbow that makes a right angle turn in a concentric vent run. It can turn a horizontal run upward into a vertical one. Its smooth inner surface helps limit the condensate, or liquid from the exhaust, left inside the bend. Choose 2 by 4 inch, 3 by 5 inch, or 4 by 6 inch to match the vent. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
The appliance cannot support the vent’s weight. Wall straps support vertical and other runs, including directly after each elbow or tee. A firestop, a protective fitting where the vent passes between floors, goes at every floor and ceiling crossing, including the attic floor but not the roof deck. In the USA, the appliance maker must list PolyPro for that appliance, and its venting requirements govern. In Canada, DuraVent lists PolyPro as a vent system itself. Need a gentler turn? See the DuraVent PolyPro Concentric 45 Degree Elbow. The DuraVent PolyPro Concentric 90 Degree Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
