Dr. I don't know what setup the Bear carver uses now but the picture he sent me had both the heat deflector and water pan that was about the same size as yours in the picture but yours is attached to the pan as far as I can tell. He stated he would move his to the left if needed. Your set up looks good .Let us know how it works out. Jted
My deflector is simpler than Dr K's, as I just put it above the water pan, and I don't trim it around the pan. The right edge of the deflector fits in between the rack holders on the right, and the left edge rests on top of an "A" shaped support, sitting in the water pan. If I need more heat on the left, I elevate the left edge a little higher by sliding the "A" support to the right a little more. If for some odd reason I need more heat on the right, I slide the whole deflector away from the right wall by a half inch or so.
I use a foil pan cut in half & set upside down above my AMNPS to protect it from drips, and it doesn't effect the smoking of the AMNPS, as long as you don't have it too close above the AMNPS.
