I got my AMNPS last week and decided to give it a try this weekend. I filled the tray about 3/4 full of apple pellets & lit one end, it burned about 1/2 the pellets then went out. I had the smoker (MES 30) running at 230º & had water pan 3/4 full of apple cider vinegar. Is it possible that the cider in the pan put out too much moisture and affected the pellet tray that was sitting on the rack directly above? Do I need to use a mailbox setup or some other method of introducing smoke to the MES?
