I will try and take some pics tomorrow. What I did was take out the flame buster. Take a piece of 8 inch black single wall flue pipe, cut it off so that it dropped 2 inches below the level of the two bars that the flame buster sits on. Then I took tin snips and cut 1 inch cuts down all the way around one end of the flue pipe and bent them inward so that they would fit into the flue opening. I think the flue opening is something like 7 3/4". I used an old piece that had the seams locked togeather for a long time. If you used a new piece you could try not locking the seam since they seem to have a lot of outward spring before you lock the seams. I then drilled a 1/2" hole through the flue just above those bars for the flame buster. I slid a 1/2" threaded rod all the way through which rests on the bars and keeps the flue pipe up. Then I took some 2 pieces of 9 gauge wire, made a hook on one end, drilled two holes through the flame buster fed the other end of the wire through the holes and bent an L to keep the flame buster from coming off of the wire, then hung it off of the hooks I bent in the wire on the threaded rod. I left a two inch gap between the bottom of the flue pipe and flame buster.
