Superior 30-Degree Offset and Return with Adapter for 12-Inch Chimney

The Superior 30-Degree Offset and Return with Adapter for 12-Inch Chimney lets you shift your chimney pipe around framing without breaking the run. It's two 30 degree elbows working together, the first angles the pipe off to one side, and the second brings it back parallel to where it started, so you end up with a clean step over instead of running straight through. This comes in handy when a roof rafter, beam, or duct sits right in the path and there's no way to keep the chimney perfectly vertical.

This offset and return is designed specifically for use with the Superior 12" Standard Wood-Burning Chimney with a 12 3/8" inner diameter and 15" outer diameter. Built with a double walled design, a galvanized steel outer pipe wraps around a stainless steel inner pipe, giving you a premium installation component for your wood-burning fireplace system. Once the offset and return sections are joined together, the total rise comes to 16 3/8" with a centerline offset of 4 3/8". The adapter is there to tie the offset into your existing 12 inch Superior pipe, so it connects cleanly without any cutting or extra work on site.

Note: Superior offset kits feature an extended inner pipe for easier connection. They now include a 6-inch transition section required when adding a straight section between the offset and return elbows (not needed for direct offset-to-offset connections). Check the fireplace manual for full specifications and compatibility.
