Working on getting one going for other brother. Used a camera and inspected the back jacket and the entire firebox is very solid. No hint of rust out. One problem is the damper only opens a small bit and I can hear debris being compressed behind it. Tried vacuuming up, over and behind and there is quite a bit of leaves and junk. The thing hasnt been burned in who knows how long. I am trying to get the damper removed and it will not budge. Any clues? Is there a special way? Any other advice on inspecting and cleaning such a hard to reach area? Thanks.
