I'm in agreement and, frankly, am curious why the answer wasn't obvious to everyone. I take off the cooking grate, set my chimney on the charcoal grate and when the coals are ready, dump them either into my Slow n Sear or my Vortex. The I simply set the chimney down on a concrete paver to cool off while I put the cooking grate back on and get ready to cook.
I can't imagine lighting it on the cooking grate. Why would you do that?
Also,
@BamaKettle, just curious as to your lighting method since you've given up on chimneys.
