I have been reading several posts regarding this. I am new to burning coal and am excited about burning it this year.
I own a Brunco Hearthglow Insert. It was just installed into an existing masonry chimney (30 ft.) which is clay tile lined and in excellent shape. The flue on the stove is 4 x 12 inches (rectangular). The installer installed a rectangular adapter to the stove, then connected an 8 inch 316 Ti grade liner (standard for my insert) to the adapter, and ran the 8 inch liner up through the smoke chamber to the first series of clay flue tiles.
Where will the fly ash most likely accumulate? I ask this because in many users' posts they reference "bottom of the chimney." What area is this? Is it the ground of the chimney, where my chimney's ash dump is? I would think because everything about my system runs down that most of the fly ash would stay in my stove or on the "ground" of my chimney as I described a couple of sentences earlier.
This forum is phenomenal by the way.
