Finally got the pipe through the damper and the offset box in place. Whew what a challenge. Here a pic of the stove and the catalytic combustor. I think its in pretty good shape. The combustor looks to me to be in good shape. I also managed to get the stove in place and am working on getting the face plate to fit. I need to cut the sides by 2 inches, as well as the top piece of the faceplate.
