i had a direct vent fireplace installed. It was vented via a coaxial vent pipe (pipe within a larger pipe-fresh comes in through the outer pipe and exhaust vents out the inner pipe). How close can 1) roxul insulation get to the pipe 2) blue foam board get to the pipe and 3) how close can house wrap get to the pipe, if at all.
Thanks
Seems as though the people making the pipe don't know either. See cop out below.
I'd certainly want a couple of inches depending on how hot it gets. The blue foam melts at 190 degrees but the pipe should not be getting that hot.
