I just bought a new smoker today, a smoke hollow pro 4400. I have a question about the flame out of the burners. I have a good flame from everywhere except form out of the first couple of holes closest to the front. From the first 3-4 holes I am getting a yellow flame that is 2-3 times higher than all the other flames. Is this normal, or is there a way to adjust the flames other than just the control knobs on the front. Hopefully this question makes sense. Any help would be appreciated. Thanks in advance.
