What's the correct way to attach stovepipe to a wood stove?
I didn't see it before, but there were two small holes in the stove's flue collar. I put sheet metal screws through the holes in to the stovepipe, and things feel really solid. 

Before inserting the pipe, I put some fire cement on the crimped end. After inserting, I spread some more around the joint, like caulking around a bathtub.
