The makers of the B-Vent Increaser say it makes installation of pipe quicker and easier, especially in tight spaces. The new Increaser has a 0-in. height, so it will not add height when two pipes are connected, while maintaining the integrity of the B-Vent flue. The design is smaller and more compact, with one-piece construction and stitch welding. It comes with the maker's positive twist locking system, allowing quick assembly or disassembly without tools or damage to pipe.
