I use an AMNPS in an MES 30 [an older one]. When it's all said and done, I get successful results every time. However, half the time, not always, I have a hard time getting the AMNPS to stay lit. When this happens I remove it, blow it to cherry red and return to MES. Usually doing this a couple of times gets it going so it stays lit. Then, sometimes I see smoke billowing out and this is because somehow the pellets ignited on the unlit end and now I've got both ends burning! What would cause this spontaneous combustion issue? As far as it going out, I know all the advice and I follow it all: CookinPellets Perfect Mix Nuke pellets for 1 min. on High Light w/ torch for 45-60 sec. Let pellets flame for 10 min. [blowing to get cherry red included!] Chip tray 1 1/2" open Chip Loader 2" out Tray on bottom rail left of chip tray Vent open full Vent with 4" elbow "chimney" foil covered cookie pan drip tray on water tray rails forming roof over AMNPS. Could over filling the AMNPS be part of the problem for either of these issues? I fill it to the top. Might I need to nuke pellets on high for more than 1 min.? Other suggestions, advice, input? Thanks folks. I love the AMNPS. I couldn't live without it.
