I have a Desa CWC42C firebox. We have had it for three years and cannot stop it from smoking up our home. We have the damper open, we have installed a vent on the side, and the stack is over the top of the highest peak of our home. Have windows open and have them closed and it does not help. Have the are on and the air off does not help. Had a fan off and on does not work. I am about to rip it out it is so upsetting.
