Our Answer:

Thank you for shopping at eFireplaceStore.com. It is very feasible to accomplish what you are attempting with rigid B-vent pipe. And Metal Fab is a fine brand of pipe with which to do it. ideally, you would begin your venting run with a Chimney Pipe Support Plate (MFB-12MHS). You may view one here: Metal-Fab Type B Round Chimney Pipe Heavy-Duty Support Plate - For Chimney Pipes with a 12 Inch Inner Diameter Metal-Fab does indeed offer various lengths of 12" B-Vent rigid pipe. Here are some examples: Metal-Fab Type B Round Chimney Pipe Length - 12 Inch x 18 Inch Metal-Fab Type B Round Chimney Pipe Length - 12 Inch x 24 Inch Rigid B-Vent pipe is one of the approved methods of completing exhaust vent runs for vented gas appliances. Metal-Fab has a full line of venting components available for completing such an installation.
