Hi all...just kind of concerned about something. Had a good roaring fire to start up the stove today...let it burn down, pulled all the coals to the front of the stove and started up a couple of splits of dry cedar (one large, the other medium). Let it char, shut down the damper to half and went about my business. Stack thermometer was reading about 450. I just went outside to do something and was shocked to see smoke coming out the chimney! So my question is, is it normal to still get some smoke even if you've done things by the book?
