Was raining today, so I took apart the Ultima for some cleaning. It's a pain to do - have to remove all the firebrick panels, burn tubes, and deflector plate, the latter two of which are attached with phillips-head screws that unsurprisingly don't turn all that well after years of flame exposure. Had to turn one of them into a slotted screw. Last shot is of the now-empty box; it was getting a little rusty, especially behind the firebrick, so I painted it with black stove paint. (After I took the pics, obviously.) The paint won't last long in the exposed areas, but behind the brick it will. Swept the chimney from the bottom, pics are looking up before and after and the pile it generated. That's a full two years worth with an air-cooled chimney; I may start going 3 or 4 years given the hassle factor.
