*Venting Requirements: This unit requires venting pipe with an inner diameter of 3 Inches. Please see the Venting Components section on this page if available for venting pipe that must be used with this unit.

Both compact and economical, this Metal-Fab Adjustable Type B Round Chimney Pipe Length is ideal for any homeowner who literally wants the most for the least. An advanced dual-wall construction allows this vent pipe to be very efficient without taking up a lot of space. It also requires just a single inch of clearance to combustible materials, giving you quite a bit of installation flexibility even if you've got a smaller home.

Another unique feature of Metal-Fab Type B Round Chimney Pipe is its innovative SureLock locking system. This patented system makes creating a secure vent connection as simple as putting two pipes together, twisting, and pushing a button. There's no need for tools and it's completely impossible for the pipes to accidentally twist apart. As a result, Metal-Fab chimneys are remarkably safe, yet require a fraction of the time - and therefore money - to install.

And, perhaps even more impressively, this Metal-Fab Adjustable Type B Round Chimney Pipe Length is compatible with a variety of other brands of vent pipe. Without requiring a hard-to-find specialty adaptor. That means that you can connect it to an existing common vent rather than have to do an expensive remodel or create an entirely new vent line. All in all, you won't find a more convenient and cost-effective way to vent your gas appliance than with a Metal-Fab Type B chimney.

*Please Note: Pipe overlaps 1.5" when joined together. Therefore, the assembled length is 1.5" less than listed.
