I have a Harman Accentra insert. I was thinking about getting a lint eater setup up. Is it easier to clean from the top or the bottom? I was thinking of cleaning from the top, and have my shop vac running at the bottom while I clean, or block the opening and deal with the ash after I get down from the roof. Or, I could clean from the bottom while running the leaf blower trick on the roof. Either way I think I'm going to have to build a support frame so that I can slide out the insert for access.
