Bought a house in Camas WA last year and it had this beauty. Obviously marked as a "Truman" but I can't find any info on it online. Has the 2 adjustment knobs on front, but otherwise I don't have any other ways to adjust airflow. The unit is in a fireplace that has the side fans, but those don't seem to do anything now that the insert is in place (they turn on and move some air, but don't seem to move any heat). Seems to eat a lot of wood and produce ok-ish but not great heat. Made it through winter in our 3300 single level house, but had to rely on the furnace as this couldn't get heat to the bedrooms (north, west and east of unit, which is fairly centrally located). The room this is in could get to 80, but not much higher. I kinda expected it to blast so much heat that room would almost unusablely warm, but it never did. The house is stucco and has good wall insulation and OK but not great windows. I tried using the furnace in fan only mode, but the wood stove couldn't produce enough heat to offset whatever was lost running through the attic. Ground fans blowing in or out of the room didn't seem to help either; I just don't think it produces enough heat, or it's all going out the chimney. IDK. My 78 year old father has used wood stoves and fireplaces almost his whole life, and he agrees it doesn't seem to produce the heat you would expect (its pretty big, don't have measurements on me, but it's no lite weight). I fixed the asbestos (or whatever that is) cord and replaced the blower assembly but I'm thinking of replacing the whole unit. I would like to know more before I make a decision as maybe I'm just ignorant on how to operate it efficiently. It seems to do better If I heat it to 700 but then it goes through a ridiculous amount of wood, and I don't get usable coals even if I load at 11pm and go to restart at 7am. Is 700 to low/high, I have no idea and I obviously don't want to damage it. Looking at the Kuma Sequoia as an option, but wood like to not spend the money if this guy can do the job. any help or info would be appreciated. If I left out any important info sorry, wood stoves are new to me and I'm still learning.
