You use the ring of fire method without the smokenator. I don't use a fire brick to seperate the ends. I just leave a small gap. I do put foil in the middle shaped like a bowl, and then fill that with a little bit of water so it acts as a drip pan so the fat doesn't drip into the bowl.
here is a good thread on how to set it up with lump charcoal.

If you do it with briquettes, just do a 2x2 snake around the charcoal grate.
