A:Answer Thanks for the question. Each burner on the FX510BGS is designed for a different level of BTUs (the amount of gas allowed through each orifice), which determines the height of the flame. The center oval burner is rated for 9,500 BTUs, which is nearly double that of the right rear simmer burner (5,000 BTUs), but much less than the right front power burner (17,000 BTUs) as well as the left front (15,000 BTUs). If your center burner does not appear to fall within this range, I would suggest contacting your installer or another licensed technician to adjust the flame height for you.
