....said my chimney sweep today as he was packing up his gear. Last winter was our first with the Osburn 2200, and I was a newb with a modern stove. Apparently my wood was good and my burning practices were sound. He said that what was in my liner was very light and came out with little effort. Thanks to all who've directly or indirectly taught me so much about proper wood prep and good burning practices. I'm really impressed with these stoves. I recommend them to all my friends who still burn open fireplaces. I'm sure they're annoyed with me.
