Four-piece adjustable elbow for the DuraVent BV (Type B) round gas vent system. Used to route a 3" Type B vent around joists, rafters, and other framing obstructions and to transition between vertical and horizontal runs. Adjustable from 0 to 90 degrees and rotates a full 360 degrees at the base so the offset can be aimed in any direction.

• Fits DuraVent 3" Type B (BV) round gas vent pipe
• Four-piece construction adjustable 0 deg - 90 deg
• Rotates 360 deg at the base for any-direction alignment
• Aluminum construction with DuraLock joint for a fast, locked connection
• For Category I natural gas or propane appliances (water heaters, furnaces, boilers)
• Not for wood, coal, or solid-fuel appliances

Tip: Elbows must be independently supported - do not rely on the pipe sections above and below to carry the weight. Install the elbow with the crimped (male) end pointing down so condensate drains back toward the appliance, and lock each joint with the DuraLock tab or a sheet metal screw per the installation instructions.
