I was cleaning creosote accumulation and the side panel to the left of the side door of my 1975 Defiant Stove pushed in and I removed it to find myself behind the fire wall. I thought that was great because a pile of creosote had accumulated back there so I shop vacuumed it out. Then I went to put back the side plate and my troubles started. I don't want to remove the chimney - since it was a pain to install it. For the life of me I could not get it to fall in place. See picture of the part. I could not find any diagram anywhere showing me how this pieces assembles into the stove.
