I installed a late model Clydesdale this fall that I really only use on weekends and other days off. The rest of the time it's not in use. I notice on days with certain weather the draft is actually down, and on those days I can feel cold air coming out of the stove even with the air control "fully closed". I have read that the air control never really closes all the way, so it's not a surprise that air should be coming out. A few times I've noticed that a pool of cold air has collected in the room with the fireplace, and that never used to happen prior to installing the insert. Presumably when the draft is up, which is most of the time, it's taking warm air out of the house that is not as noticeable but is equally costly. Any advice on what can I do about this? Thanks as always!
