extra parts....

Ive been installing my supervent stove pipe today and got it from my stove to the ceiling but I have an extra part. It came with the universal chimney pipe adapter. It has two holes on it and looks like it wraps around it somewhere. Kinda stumped, don't wanna be tearing it apart in the winter. http://www.menards.com/main/heating...niversal-chimney-adapter/p-1323231-c-6890.htm

This is what it came with it, can really figure it out. Anybody else use this?

Came in the box with the chimney pipe adapter. its a band of steel about 2 inches tall with 2 holes at the end, kinda like a huge braclet.

yes its sellkirk. I'm guessing then its supposed to cover up the 3 holes in the outer casing of the upper part?

Thats what i have but, it came with this http://www.menards.com/main/heating...niversal-chimney-adapter/p-1323231-c-6890.htm
What do I use then? The band or the chimney adapter?

Page 2 states to only use one of them. I do have one spare part
