This is the bottom rack that holds the water bowl and the chip tray upside down with the AMNPS in the place of the chip tray and somewhat snug to the water bowl side
I moved it to the water bowl side for one important reason, the AMNPS needs air, and the air inlet for my model is dead center of the bottom panel, so this way, incoming fresh air will be more readily available rather than placing over the other way, the fresh air inlet will be right between the water bowl and the AMNPS (under it of course) and the air would be naturally flowing under, past and across the bottom of both the water bowl and the AMNPS, this way the AMNPS will always have a supply of oxygen rich fresh air to prevent any issues with the pellets not staying lit or just sloppy smoke distribution inside the cabinet.
Also since I see that many have had a issue with the AMNPS going out due to lack of air, I wanted a way to secure or fix the position the AMNPS is in and to make sure it would consistently be in the same position always, this mod grants all of those factors, it secures it next to the water bowl and it secures it in the same position every time I put it in.
All that said, the MOD is easy and requires no parts, one tool, I used a angle grinder, but I know there are many ways to get the same result such as a Nibbler maybe, but it is stainless and I did not want to damage my Nibbling Tool on hard metal which is rather thick too regarding a Nibbler.
Anyway, I used a screwdriver to hold up the AMNPS in place and made marks on the small flat bar rails that support the AMNPS, and all I did was use the angle grinder to grind out recesses in the flat bar supports on each corner and additional ones for that cross support wire, so now when I set it in there, the recesses allow the AMNPS to sit lower and to held in place, when done like this it can be turned 180 degrees and then be away from the water bowl, but I want it this way to force and or induce air to the AMNPS.
Here is a shot of it done
Not really that big of a deal, but if my smoker were to be bumped now, it surely will not move, as it is sitting over the wire in 4 corners and on that cross support wire as well, and not only that, but it will be in the same place every time, most importantly, it will be positioned very well over the air intake hole in the bottom, forcing fresh air to pass by and under it to ensure the pellet smoker will not be starved for oxygen and arbitrarily extinguish and it will also move smoke generation to a better center weighted spot to enhance smoke distribution.
Here is the Finished Product in place
You see how the wire is above the bottom of the flat bar supports under the AMNPS, the wire literally sits up in the recesses on each corner, and the cross support wire does the same sitting up into the recesses of the flat bar as well holding it from sliding left to right
I have another mod in reference to positioning the AMNPS, but I will reveal that one later, now all I need is a drip guard for the AMNPS so grease or fat dripping will not snuff my pellets out and get ashes all over meat !
That mod is on the way too !
