I had reported ealier that I had a belly sag in my baffle. I took the stove apart yesterday to see if the seal was good on the secondary air inlet because I too was getting secondary from the rear of the stove. What I found surprised me. In the back, bottom edge of the baffle there is a, for back of a better word "flange", that runs across the full length of the baffle. UNDER this flange are secondary air holes (all the way across just like the ones in the front.) So its my assumption that secondareis from the back of the stove are expected to happen. Also the back edge of the baffle was straight as an arrow so no leakage was occuring.
