Abstract:
A vent pipe extension and flashing apparatus for extending a vent pipe into a chimney including a generally vertical wall having an interior surface, an exterior surface, and an opening through the wall. The apparatus comprises a threaded sheet metal pipe including helical threads extending along substantially the entire length of the outer surface of the threaded pipe, the threaded pipe having opposite first and second ends, the first end being adapted to extend through the opening in the chimney wall, the second end being adapted to be connected to a vent pipe. The apparatus also comprises restraining means for engaging the interior surface of the wall to prevent the threaded pipe from being pulled back through the opening, the restraining means being supported by the first end of the threaded pipe and being compressible to allow the first end of the threaded pipe to be pushed through the opening in the wall. The apparatus further comprises means for surrounding the second end of the pipe and engaging the exterior surface of the wall to cover the opening and including a member adapted to be threaded onto the second end of the threaded pipe.
