Cleaned chimney and inside the top of the fire box. There is no draw anymore until the chimney is heated. This is a problem because at night when I am sleeping the coals will burn down, chimney will cool off and then the back draft will start heating the coals but then pushes the smoke out into the house. I am looking for a manual or something so I can figure out and make sure everything is set the way its suppose to be. CFM Corporation, Intertek Warnock Hersey Model: FW300007
