Hi, in the end of Dec I had the chimney cleaned. It had clogged bad after only 3 months of burning. Long story short - the handyman that cleaned it in the summer wasn't thorough. But now, 6 wks after a professional cleaning, it's a bit clogged. Wood is dry, 4 days worth in the house at all times... about 5 feet from the stove. When I add wood (to the Kuma Tamarack) I take it up to 475 or so & in 3 or 4 hours (when it cools down to 280 or 300) I add more. Am I taking it too low or did I get another bad cleaning? Thank you. Laura PS Some pieces do have pitch - could this contribute this much to clogging?
