A reignition device (32) for a gas burner includes a reig- nition flame chamber (31) which opens into a burner face of the gas burner. The burner face is also provided with a plurality of circumferentially spaced burner ports (28, 29). The reignition chamber (31) includes at least one port (98) for receiving an air/gas mixture flowing within the burner head. A reignition flame is initially ignited at the reignition chamber by a burner port flame or an electrode (47) which also can be used to ignite the gas flowing out of the various burner ports (28, 29) in the burner face. The reignition device (32) is designed so that the reignition flame burns in a balanced and stable manner both when the burner is set at a high rate and when the gas burner is turned down to a low setting. Subsequently, should the flames about the burner face be extinguished by an external influence, the reignition flame will remain ignited and will function to reignite the burner flame.
