Appreciate the great comments on interior masonry chimneys on an older thread.  About to remodel and ready for new chimney but wouldn't have to be masonry.  Considering a boxed in 6" metal up interior wall thru a cathedral ceiling   (1) Could you  thimble into it thru wall same as with a masonry?  (2) What would the cleanout be like?  I'm guessing it would be a cap/plug at bottom so you could run a brush all the way down through it.  (3) With  this type installation would you make front panel removeable so as to be able to examine chimney top to bottom occassionally?
