Last night I noticed that I wasn't getting any type of secondaries. Turns out that the top plate of the secondary air manifold warped and no longer forms a seal. Please take a look at the picture below and let me know what you think. If you look closely you can see the gasket coming down at an angle towards the right side of the center tooth. This morning when the stove was cool the gap was much smaller. This picture was taken at about 500 so the hotter it gets the wider the gap becomes. I bought the stove used and unfortunately the baffle and manifold are warranted for life only to the original purchaser. Any thoughts?
