DuraVent PolyPro Support Elbow Extended: turns the vent upward and supports the chimney run
The DuraVent PolyPro Support Elbow Extended is a 90 degree elbow that sits at the bottom of a chimney. It turns the vent from the appliance upward and helps hold the vertical pipe steady. Its extra horizontal length can be cut to fit. The base rests on a flex or rigid support bracket, or a flex chimney support. This elbow is also part of the flex chimney lining kit. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters.
One locking clamp is included. Choose a 2, 3, 4, or 5 inch size to match the flex, the flexible liner inside the chimney. That liner does not attach directly to the appliance. Rigid PolyPro pipe reaches the chimney base, where a male flex adapter joins it to the liner. A female flex adapter returns it to rigid pipe at the top. The liner is cut to length on site with a saw or knife along a groove. Need a base for the elbow? See the DuraVent PolyPro Flex Chimney Support bracket. The DuraVent PolyPro Support Elbow Extended ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
