Questions & Answers

Question on Damper size

I need to order a Lyemance Top Sealing Damper. The flue at the top of my chimney is a rectangular clay pipe. The width of this pipe is 10 5/8" inside - outside dimensions are 13 1/4". The length of the existing flue is 15 1/4" inside - 17 1/2" outside. The 12 X 16 damper dimensions does not specify if the flue sizes that it fits are inside or outside dimensions. I therefore am unsure if this damper will work or I need to order the larger 13"x17" damper.
