first time on the forum... I have a VC defiant encore (with catalyst) vintage 1989, it is installed on the first floor in a big living room (great room) Presently, the combustion air is pulled from the room, or we occasionally open a nearby window both arrangements tend to be drafty to very drafty the wall behind the stove is a brick "false wall" with a 3" (or so) airspace between the brick and the wall board behind it there are 26 openings at the top and bottom of the wall for air circulation, each opening is 1/2" x 4" that wall is an outside wall I was thinking of my own fresh air kit - putting an opening in that wall to bring in outside air for combustion. I figure it would deliver the air to the warmest part of the room, distribute it thru the openings and reduce the drafty feeling we currently have can anyone imagine the problems I might encounter? condensation inside the wall space? the need to out a "check valve" to limit airflow out when the wood burner is not going? pests getting in the vent? (put a screen over it) will the air cool the brick which serves as a sort of radiator, too? thanks in advance!
