I purchased a used Napoleon 1900P a few months back. In cleaning it up I have noticed two areas that show signs of over-firing. The first is the middle support bar that has holes in it. This is not the replaceable piece, it is the H shaped piece that looks to be welded to the stove. It is warped and sagging a little in the front. The second place is the metal plate on the ceiling of the inside of the stove. Looks like a welded on plate that I am guessing is there to help dissipate heat in that area. Mine is warped down near the front of the stove. See the pics... am I asking for trouble if I use this stove?
