Sealing drafty gas fireplace
I have a gas fireplace that has a pretty significant breeze coming from the bottom vent area when the north wind blows.
Here's the problem (click to enlarge): From misc
This does not lead directly outdoors. The breeze seems to come through the direct-vent chimney, around the back of the fireplace and out this hole. What can I safely use to seal around this gas pipe under my fireplace? Thanks!
