First timer, no experience here so I have no idea what I'm doing. How close should the chip bowl be to the heating element? I assembled a cheap Masterbuilt bullet electric smoker and the instructions were... vague. If I install the heat shield (beneath the heating coil) one direction, the chip bowl sits maybe 1/2" or more above the coil. If I have the shield the other way, the chip bowl is basically sitting in full contact with the inner ring of the coil. So which way should it be?
