DuraVent DirectVent Pro 8×11 Adjustable Pipe: a sliding length for the gap between fixed pipes
The DuraVent DirectVent Pro 8×11 Adjustable Pipe is a vent pipe with two sections that slide together. It spans 15 to 22 inches, with 7 inches of travel to bring fixed pipe lengths to a wall cap, ceiling, or second elbow. DuraVent’s usual placement is between two elbows that take the pipe around an obstacle. DirectVent Pro 8×11 is DuraVent’s large size pipe inside a pipe vent for big direct vent gas fireplaces, with an 8 inch exhaust pipe inside an 11 inch air pipe.
The ends lock with a turn, without a gasket or sealant unless your fireplace maker calls for it. Allow for 1 5/8 inches of overlap at each joint when adding up pipe lengths. The 45 and 90 degree elbows turn at their bases without unlocking the connection, but their bend angles stay fixed. A pair of elbows and connecting pipe can pass around a joist or beam, with an elbow strap supporting it every 4 feet. The fireplace maker sets the limits for that detour. Need the fixed sections?
