How warm does the gas pipe get where the exhaust pipe touches it?

You could fold a couple layers of fiberglass cloth and slide it between them. Or just re-position the vent pipe a bit. Maybe just run a wire around the vent and pull it away a bit to get rid of the rattle.

Did they teach you that at MIT?
