re: Temp swing of your green mountain grill

After calling Green Mountain I figured out the problem my grill came assembled and they didn’t install the heat shield at the correct distance from the wall. I now have the heat shield at green mountains recommend 4 1/4” (Daniel Boone) and it is staying within 4 degrees of set point. Apparently if the heat shield is off by less than a half an inch it can cause huge temperature fluctuations and probably why my ribs didn’t get the bark I wanted. Also why I was running through pellets
