Hey, looking for a little guidance. Now that it is the shoulder season again, we aren't needing fires as often but wanting to take the chill off happens on occasion. I have been noticing that from our single wall to double that smoke has been leaking when I have the door open during a start up. Wondering why this is happening now as it never did before. Any thoughts? Here is a pic of where I am getting the smoke.
It is leaking out at the first two double wall seams.
