I am trying to figure out if a flue damper will benifit me at all. what exactly will it or is it supposed to do for temp of stove,wood consumption,burn time,heat output. I have 30' of chimney and a real good draft,the stove is vented out the back and has a heat sheild in place, I only have 6 " of space between the stove back and the slate tile on the wall " within min clearance with shield" If I were to put in a damper it would be verry close to the stove and I might also have to cut a small hole in the side of the shield to be able to operate it all this considered, is it worth the effort ? Thanks, Darren
