Inquiry (采购产品): backdraft damper Hi In my web search, I think you have what I am looking for. I have a Portland Stove fireplace that was installed 25 years ago without a damper. I heard that someone manufactures a damper that sits on the chimney flue and when heat is present, the damper opens and when there is no fire/heat the damper closes. Do you produce such a product and if so how much and if you don't make it ,Do you know ware I might find it.
