DuraVent PolyPro Flex or Rigid Support Bracket: holds the elbow beneath a flex liner or rigid pipe
The DuraVent PolyPro Flex or Rigid Support Bracket is a bracket that holds a support elbow inside a masonry chimney or chase, an enclosed passage for the vent. It supports either a Support Elbow or an Extended Support Elbow beneath a flexible liner or rigid PolyPro pipe. One bracket size fits 2 to 8 inch vent sizes. PolyPro is DuraVent’s polypropylene vent pipe for high efficiency condensing gas boilers, furnaces, and water heaters. The vent’s weight belongs on its straps and supports, not on the appliance.
A firestop, a barrier around the vent opening, belongs at each floor and ceiling the vent crosses, including the attic floor but not the roof deck. For a PolyPro Flex installation, the appliance manufacturer must approve its use with that appliance. Only DuraVent terminations, the parts that end the vent, are used with it. An existing chimney must also be inspected and found sound before serving as the chase. Need the elbow this bracket holds? See the DuraVent PolyPro 5 to 8 Inch Support Elbow. The DuraVent PolyPro Flex or Rigid Support Bracket ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
