Just had my chimney swept for the first time since the Progress install on 12/8. Only got a cup full of very fine coffee grounds (like powder). Chimney sweep thinks one sweep a year will do it, two to be extra safe. He also installed the new door gasket and the ashlip (well, I installed one screw and was wrestling unsuccessfully with the other screw as my dh made dire predictions about the outcome when the sweep took pity on me). Unfortunately, have to wait 72 hours (!) for furnace cement on door gasket to dry before we can use the stove. Arrrrgggghhhh! There we go with that patience factor again :-/
