Thanks, guys. Chris, I just removed and modified the existing ductwork on the outlet side of the oil furnace. The actual duct was made by a professional! The furnace was installed in November, 2007 after the "big flood". My homeowner's policy paid for all of it except the $500 deductable. I was just starting on my second season burning coal. If I knew then what I know now I would have installed a stoker furnace. I do remember thinking "I should install a coal furnace here".
As far as servicing the EFM, it's very tight. I can't remove the whole stoker assembly, pot and all. I have to separate the pot and take it out through the ash door, then I can pull the stoker mechanism off.
