Metal-Fab B-Vent Big Vent Vent Cap - 22MC

Metal-Fab's round Type-B vent is listed by Underwriters Laboratories for use with approved category 1 gas furnaces, heaters, and boilers. A category 1 appliance operates with a non-positive vent static pressure. The double wall design of B-vent enables the product to be used in homes and commercial buildings at close clearance to combustible. Metal-Fab's B-vent design incorporates features that make installation quick, easy, and safe. Some of those features are:

* Elimination of sharp edges by hemming the flue and casing.
* Assembly and disassembly, without tools, using positive twist lock.
* 360 degree rotation of small diameter fittings using swivel tees, wyes, and elbows.
* Space savings inside standard stud walls using oval pipe.

Commercial Vent or "BIG Vent" is available in round sizes of 14" - 30". Big Vent sections (in 16" - 30" diameters) are joined together using Metal-Fab's quick connect locking system.

We strive to ship within 5-7 business days, but in-season delivery can take up to 2 weeks or more. If you have any questions or concerns about delivery, please e-mail us at: info@woodstovepro.com
