My husband and I purchased a house with an insert woodstove, and we cannot figure out how to get it working. It is a silent flame, but the plaque with model number and info is illegible. It is wood burning, I am used to an old school fireplace. I cannot figure out how to open the damper/flue. There is a rod at the top, only the knob at the end of it turns 3/4 of the way, and I cannot see that it does anything. There is also a rod at the bottom which goes in or out, no idea what it is supposed to do. Also a button along the side which can go to auto, off or manual. None of the settings seem to do anything. I would love to find a manual but I don't have a model number. Help???
