I cleaned my flue tonight, and I always have a tough time getting the pin for the baffle back in. This time I sorta put it in backwards so it isn't flush....It's bothering me, and I need to correct it tomorrow. Problem is, it seems as if the baffle goes up in the rear ever so sleightly and the holes don't line up...Is the baffle warped...I checked and its not sitting on debris or anything....help!
