Hi all, I have a Fisher fp insert wood stove. I have it in a fireplace that has a heatilator. Last year was my first year using it and it worked great. The stove came with a faceplate and side "wings" that are supposed to be used to seal the insert into the fireplace. I believe that in masonry fireplaces, this keeps the heat in the room and not going up the chimney. My fireplace is a heatilator and the size of the opening is larger than the faceplate (and side wings). So I have two options (maybe more, but I see two) -- one is to take the faceplate stuff off and just let the heatilator reflect heat into the room. The other is to get a welder to enlarge the faceplate stuff so that it covers the opening to seal it (I know a welder who can do this). Which would maximize the heat in the room? Thanks!
