I had the guys from the stove shop come out to clean the chimney, 'cause I was having some problems with smoke coming into the room. They cleared off the cap, and the smoke problem was 80% better, but still a little bit of smoke entered the room. Then, they decided to remove the firewool blanket, and now, the smoke problem is gone. By the way, the firewool seemed to be "saturated" with ash. So, I'm wondering: is it's o.k. to leave the firewool blanket out? Does the baffle reflect enough heat back into the firebox to provide for a clean burn, without the firewool? Will the stove run hotter, with a greater danger of over-firing? It sure is nice to be able to open the door as wide as it goes, and not have any smoke come out!
