My oven opening is approximately 250 square inches. 1/10th of this is 25 square inches. So if I go with a rectangular flue from Superior Clay (Superior Clay Flue Liners) the closest standard size (with out going undersize) would be the 4.5" x 13" which hs an effective flue area of 34 square inches. This seems like an awfully small flue compared to some that I have seen. If I went with the round flue it would be a 6" diameter.
Thanks again for all your help!
