No fire tonight so I though I would take a look at the inside of the stove and what I found just about made me throw up. In the corner of the air channel on the left hand side I found a hair line CRACK. The air channel itself is no cracked I don't think just looks to me like the weld cracked. Over the last three years when I load the stove I always make sure no flames are directly hitting the air channels and I have yet to see it happen. I have been very careful of this because I have read where they will crack. ALL Lopi owners please inspect the corners of the air channels VERY carefully.
