I cannot run my stove right now while we wait for the chimney guy to come over and give it a clean out. So, me and the G/F spoke about getting a new stove for the 2009 burning season. (we need a bigger fire box) We already know that we will be going with welded pipe from the stove to the wall, and we spoke about an outside air kit. My question is, do they REALLY make a difference, I know it will NOT pull air from inside the house but is it noticeable? Also, when the stove is not running/ running slowly,can you feel a draft from the outside air kit. I would assume that the fit from the air kit to the stove is NOT air tight and air must leak out no matter what. Thanks for any input that you can give.
