Fireproofing Advice

I used 2" pink foam board around my basement and then put up drywall.

For the section where the wood stove outlet goes thru the wall, I have the 2' foam board up, and I plan on going up with 1 1/2" furring strips, then 1/2" cement board, and then my Faux Stone panels. However, I have a cavity where the pipe can radiate high heat onto my foam board. Do I just fill the cavities with fiberglass? Or is there a better way to fireproof this?

Thanks for any advice on this matter

The exit pipe should go through a terra cotta nipple, or triple wall pipe, so heat should not be an issue. A direct single wall pipe should not be used to penetrate your wall.

Yes there is a clay liner inside of the outlet pipe. Even running the stove all day wouldn't be a danger?

So I take it just filling with fiberglass would suffice?

You must maintain clearance to combustibles, so filling something with fiberglas may not work. Fiberglas is not considered non-combustible. Roxul, on the other hand may give good results. How did you put up your wallboard on the foam? Just glue?
