Hello, Yesterday I had a new C350 insert installed in my ZC fireplace. The stove looks great and seems to be burning quite well (measured 600 F with an IR thermometer). I have only had it a couple of days, but it seems to put out zero heat. I didn't expect to heat the whole house, but I thought it would add some heat to the rear of our house which is about 800 sq feet. As a matter of fact I think I feel a draft or considerable cool air movement while the stove is burning. I might even go as far as say the room is less comfortable while burning. Any thoughts on this?
