Hmmm, I usually just put it on the grates. I have a variation to that though. When I use the Wolf I use all the burners on medium to just over and I turn on the big infrared rotisserie burner in back. With the lid closed it heats up to a fierce amount of very even heat. I can cook 2 to 3 very nice crispy pizzas on it without pre-cooking/browning the crust. I literally just throw the za right on the cast iron grates and leave the IR burner on high. Toppings and bottom cook perfectly and the result is as good as anything I ever ate (even in Italy from wood-fired ovens). I even sometimes put a nice chunk of wood on foil on one burner and it gives that very subtle smoke flavor like I remember from Italy. I would highly recommend it to anyone who has a Summit with IR burner. The only caveat for some of the newer Summit owners is the grate bars are spaced so far apart the dough will sag though. I don't have that issue as the cast iron grates on the Wolf are only about 3/16" gap.
