brock, i would highly reccomend against burning bit in your 130, it might be interesting to try it, but really don't think it will work out, especially for any sustained use in that appliance, it's just not designed for it.
Smitty, i'm glad you enjoyed your bit coal
If you want to burn bit on a more regular basis, you will want to do three things, remove the screen from your chimney cap, put T's instead of elbows in your connector pipe, and "bank" the coal when loading rather than spreading it out on top- this will reduce the density of the smoke and allow a much cleaner, less smelly burn. Also If possible, you're going to want large sizes of low coke button coal, especially something like a kentucky lump if possible - around 14,000btu's/lb and burns long, steady and controllable with low ash.
as far as cleaning the chimney, other than any horizontal run of connector pipe (or connector pipe smaller than 7") you won't have to sweep the chimney, the soot will just periodically fall off inside the stack, just be sure to check your clean-out periodically.
If anyone around buffalo is interested in trying some kentucky lump or other bit coal, i keep it on hand and will give a couple buckets to you.
