sealing stove pipe at firebreak

DoRight's picture

I have a new wood burning stove.  The double walled pipe enters the attic through a metal fire block.  However the  block does not seal tight to the pipe.  What chaulk or foam can I use to seal this block so as to stop air from moving up through the gap from my interior chimney chase?

Google "fireproof caulk".

Sure, I can do that. And I have.

I guess the questions are:

Is chaulk the right product?

Is a foam better or possible?

What is typically done at this gap?

If you stop that gap up with anything you will violate the fire rating on the pipe assembly I believe.

What did the pipe manufacturer suggest?
