DuraVent Model BV Large Diameter 45 Degree Elbow: a bend that routes your vent around framing
The DuraVent Model BV Large Diameter 45 Degree Elbow is a bend for a 10 to 30 inch gas vent run. Two elbows with straight pipe between them move the vent sideways to get past a rafter or joist. The 10, 12, and 14 inch sizes can be set anywhere from 0 to 45 degrees. Sizes from 16 to 30 inch stay at a fixed 45 degree angle. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Choose the diameter that matches your Model BV run, from 10 to 30 inch. The vent needs support on both sides of the change in direction. For these sizes, the firestop support plate holds the pipe and closes the floor opening around it. Its two halves bolt around the pipe and carry up to 30 feet of vent. Need a square turn instead?

The DuraVent Model BV Large Diameter 45 Degree Elbow ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
