Stop using the burner and obtain appropriate advice. The intended flame arrangement should not be guessed from a similar-looking hob.
What the observation means
If owner-removable pieces were recently cleaned, incorrect seating is relevant history, but it does not justify adjustment while hot or repeated ignition attempts.
A useful next step
Follow the manual only for permitted cool, safely-off reassembly. If normal operation cannot be confirmed through its procedure, leave the appliance unused for assessment. Do not file parts, enlarge ports or continue cooking around a visibly abnormal flame.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
