Very happy to find this forum. I have an old Fisher woodstove in a house we recently bought. The 8" pipe feeds horizontally into a brick wall to a masonry chimney.

I was cleaning things out last week and noticed after pulling the pipe from the wall, there was a small, finger-width gap where the brick met the ceramic chimney. It looked like there maybe have been some cement there that perhaps had broken, but I saw no evidence in the clean-out.

The red dots in the drawing below mark where this gap sits. My questions are:

1. Is this alarming? Perhaps all the heat and smoke get sent to the chimney, so maybe not?
I went to the attic to see if there was any evidence of heat/smoke etc from above the wall and saw nothing.

2. Proper solution and/or most logical remedy?
