I am new to this site and I apologize if I have posted this in the wrong place. We just bought a house (2280 sq ft) with a D D King Wood-burning Furnace. Does anyone know how to use this? The house is 40 years old, but I don't know how old the furnace is. The company on the tag (Davison Mfg Co, Marshall, AR) is no longer in business. I had a Hardy in my other house and loved it, I would love to use this one, but I am afraid to. Please help! I thank you in advance!
