In keeping with my "over on another site" theme, there have been some folks who modified their smoker (very similar look, different make) by enlarging the existing hole, or drilling additional holes in the bottom to increase air flow. Of course, it was acknowledged that the warranty was voided, and I would guess that would include the heating element, probe, controller, all of it. Then came the predicament of where specifically to place the AMNPS, left, right, where.
Judging from comments, I suppose it worked. The reason for the mod? They were after the "thin blue smoke", and smoke that would last for the entire smoking process be it 4 hours or 16. Some sort of plug was fashioned to plug the holes when not needed.
