Oil Furnace swing exhaust damper (swing which way?)
I have an oil furnace which has it's swing damper swinging outward (like in the pic below). I was checking out a friend's oil funance and saw that his swing damper swings inward. Which way is it supposed to swing? I googled up the pic below to show what mine looks like (similar) but the site I got it from was warning that if your air intake was in the same location (mine is 4' lower than the vent) that it poses a problem of sucking in exhaust fumes. In or Out? Was mine installed backwards? Thanks for any answers!!
