I tried the Cornell chicken recipe (no water in the pan) on my 22" with the Flame Boss temperature regulator. I used a little less than two full Weber chimneys for fuel. The recipe called for a temperature between 325 and 350. I set the Flame Boss for 325. The Flame Boss fan was going 100% the entire time but I had difficulty getting the temperature above 300. The chicken was done in about an hour which was fine but I am wondering about my technique. 1) Not enough charcoal? or 2) Did I install the fan in the vent incorrectly (does it matter if the fan is not directly opposite a hole?)? or 3) The Flame Boss has difficulty maintaining a 300+ temperature in the 22"?
