I tried several different settings for the top and it did not make much of a difference. The 19 only only has one vent on the bottom. Next time I will try to pull the bottom vent plate out to increase air from from the bottom to see if that is the issue.

I have a 19" table top and having issues getting the grill hot when the pizza stone is in place. I followed advice on this forum to use large chunks of charcoal for maximum air, bottom vent open all the way and top open about 3/4 of a turn to maximize draft. With no stone on the main grate, and the charcoal fire going well, the dome temp runs right up to 500-600 degrees. If I place the stone in place, the dome temperature drops to about 300 and it takes hours to get it to 450. I let it run even after cooking to see how hot it would get and it never went over 500 - about 5 hours after putting the stone in. Seems like the stone blocks airflow, limiting temperature rise? Tried different settings of the upper vent but pretty much the same. Any suggestions?

Is that the standard upper grate that came with your 19"? I have the 19 but mine came with a 2nd grate that only sits a few inches above the main grate? The legs on your upper grate seem to be about 6" - mine are 2"? Just wondering if I received the wrong grate. Thanks
