An oversized flame can heat handles or surrounding areas instead of the pan base. Pan dimensions and burner selection must follow the manual.
What the observation means
Turning a large burner fully up beneath a small pan is not automatically faster or safer. Unstable cookware and overhanging handles add separate hazards.
A useful next step
Use a suitable burner and pan under the stated guidance. If the flame remains abnormal at normal settings, stop and obtain gas assessment. Do not modify jets or restrict gas flow with improvised adjustments to create a smaller flame.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
