I went ahead and disassembled the burner pan. As you can see in the first picture the mixing tubes where sticking out at different lengths. A problem that need to be fixed but I was unclear of the solution until I stripped it down and found out that they were just pressed in place. An easy fix. Upon inspection I found the Ottoway burn pan to be badly warped on the bottom, with differences between the peaks and valleys being almost a full inch.
