I saw a close out z-grills today at Menards and figured I could use the hopper assembly for my AZ bbq outfitters Boothill cooker. My smoker came with a pre-cut rectangle to accept a hopper assembly that was covered by a steel plate. The Z-grills screw configuration matched the pre-drilled holes on my boothill so installation was very simple. I have not played with it much, but I'm having a little trouble getting the cooker up to temp. I know it is not easy to trouble shoot from these pics, but I thought maybe someone would have some ideas.
There was already a hole drilled for another reason so that is where I put the temp probe into the side of the cooker. The temp probe that came with the pellet hopper may read around 260, and the grill thermometers may say around 215-220. The pellet probe and the grill probes are essentially on the same plane, but the pellet probe is slightly closer in proximity to the heat source.
The steel plate in the picture acts as the drip pan. The plates in the cooker to the far left and right are vented, so I can completely close them or let them fully open. You can see in the bottom that i have the diffuser that came with the grill in place over the firepot. So aside from the vented steel plates, it is fairly close to a traditional pellet grill setup aside from all the 3/16 steel to heat up.
I guess my dilemma is this: If the temp probe as its placed is reading high and the grill is low, then I'll never get much smoke as I'm trying to keep the temp up in the chamber. If I move the probe so that it reads hotter which will make it cycle on and off to produce more smoke, I still will never really be able to achieve the chamber temps. Anyone see any obvious problems or solutions?
