I just had a direct vent gas fireplace installed in a corner of my basement. I'm about to start framing it in so I can drywall the entire corner (ceiling to floor, with a space for the fireplace, of course) My question is whether I should wrap insulation around the vent pipe. It gets very hot to the touch. I know of a good wall insulation called Safe N Sound, which is non-flammable.
I've had one "expert" tell me to insulate and another says I shouldn't.
