Unfortunately if you do that LA, it would mess up the way the pit runs. It was designed to run with the bottom vent set to your altitude and with the 4 holes to have the rebar ran through them for the cook. This is nothing like a UDS where you can get away with adjusting the airflow to slow down the burn. I have learned with my PBC to just light the coals,wait 20 minutes and get cooking and I just gotta say it:
"It is so neat, to hang your meat!!"
