It should not be managed by holding the control in an improvised position or bypassing safety features. Record the setting and burner concerned.
What the observation means
The normal minimum flame and adjustment arrangements are model specific. An owner should not turn internal screws to create a stronger low flame.
A useful next step
Stop using the affected function and seek appropriate gas assessment. Follow emergency advice if gas is smelled. Do not keep testing the lowest setting with food unattended or assume that using only maximum flame makes the unresolved fault safe.
