I have burned wood for 40 years. Barrel stoves, older style Earth stoves, Ashleys and such. Now I have a beautifully burning Morso stove that is doing great. It is a large stove with a 6" flu that quickly adapts to an 8" pipe and is connected to an 8" clay chimney. The Chimney is tall and goes above the ridge of this ranch style house. It draws very well, no problems there. I burn dry hard wood and have great, clean and very hot fires. I always see the gasses burning through the jets across the top of the fire box and the glass stays very clean all the time. Sometimes the firebox is full of beautiful flame as I often have the air supply open 50% or a little better to heat this large house. I wonder if I should have a damper on this stove? I have never had a stove installed that didn't use a damper. This burns so clean and hot, but I would like to get it hotter of course without sending all the heat up the chimney!. I have no idea about this kind of stove with the secondary burning and all. I see many stoves like this without dampers. But I have this great draw and all. I look forward to the recommendations.
