Sealent for furnace exhaust vent

I have rebuilt my furnace and now I need to cut a new access hole in the roof for the vent. Any idea on what type of sealent can I use around the pipe that wont melt from the exhast heat, and seal it from any water that may get under the cap that covers the opening?

Still looking for information. I will need to make a new pipe coming out of the top of the furnace going thru the roof, so I will also need a sealent to use on the pipe as well. Figured I can rivet the pipe together, but still need something to seal it from letting the gases out ?

Dan, I'm wondering the same thing. I'm replacing my furnace, and the vent tubes exit the side of the trailer. The installation guide says to use caulking, but doesn't specify what TYPE of caulking. The surrounding vent has to get really hot. Too hot for regular caulk, I would think.
Maybe Andy with Inland RV has some info?

I recommend RTV silicone, such as TremPro 644 High Temp RTV, SikaSil-GP.

Work is never done, so take time to play!
