All our gas and dual fuel products are fitted with a flame failure safety device that stops the gas supply if a flame is not detected. If the control knob is not held in for long enough (typically 5 to 10 seconds), the safety device will not be operated and the flame will cut out.
Ensure all burner parts including thermocouple and electrode are clean, dry and fitted correctly (see user instructions) and that that there is no food debris or grease around the small brass injector in the burner body
