I recently installed a Kent Barker log fire insert it came out of an old fireplace brick fireplace that was in a home from the 1900s anyway I believe this stove is from 1982 and I have all the pieces and parts and I installed it in my home with the body of the stove on the exterior of the house and just the face facing inside in my kitchen. There is two dampers one that controls a pan style damper on the chimney and then one on the front of the stove for air intake how do I work these two together to get the best result?
