I have a question about how sections fit together. I recently assembled a new chimney and found that the inner 6 inch tubes did not fit well into each other. There were gaps of about 1/4 inch in places. I called Selkirk and their response was that it was normal and that expansion and contraction would allow it to settle into place in the future. Does anyone have any experience with this problem? I found it very odd and troubling. :-/
