The one-piece, stitch-welded B-Vent increaser makes pipe installation quick and easy in tight spaces, the company says. According to the manufacturer, the vent increaser maintains the integrity of the flue and results in no added height when two pipes are connected. The B-Vent increaser uses a twist locking system for quick assembly or disassembly without tools, says the company.
