Hey guys, sorry if this has been covered but I've searched and can't seem to find anything on my particular issue. My 5x8 AMNPS Tray burns perfect with dust but when I use pellets it goes out halfway through the maze. Every time it goes out exactly halfway through. I'm using pellets for more smoke on some things. I get a good white ash and air flow doesn't seem to be a problem. I also nuke the pellets. I'm sure it has something to do with the draft but I don't know how to correct. I pull it out and light the other end and it burns all the way to where it stopped the first time. Any ideas why the pellets would go out halfway through the maze and how to correct?
