I attempted to smoke salmon in my MES 40 today using my amznps. I filled the amznps with apple pellets. I used the blow torch to light boths ends of the pellets. I lit the ends and let them burn for around 10 minutes as directed. I closed up the smoker and checked around 15 minutes later and it was still smoking. Two hours later I went back and no smoke. When I looked at the amznps,there was only a small portion of the pellets burned. I restarted the pellets burning again. I made sure to really put the blow torch to it. Go them burning good and blew out and relit several times. Once I let it burn for awhile, I put back into the smoker. I have the tray pulled out about 1 1/2 " and the wood feeder is out about 1". It went out again! I am not sure if it's the apple pellets that are hard to burn or something else. I used hictory pellets last weekend and didn't have this issue.
