Hi I wonder if anyone has thoughts on this. I'm getting a used Hearthstone Clydesdale insert that is missing it's fan and fan assembly. That's kind of OK by me because apparently eveyone hated the existing fan setup. Anyway, I'm working on my own setup that will actually sit down in a brick bench hearth in front of the raised fireplace, but I'm thinking I want to be able to either suck air in down into and through the hearth to heat it and blow the air out into a more central location, or blow air through the hearth up through the insert and out in the traditional way. Does anyone know of a ductable fan that could do that?
