Abstract
A sealed gas burner assembly provides fast spark ignition of the primary air/gas mixture by supporting the electrode in an electrically insulative member that is disposed in a fluid-tight sealing engagement through the electrode aperture of a burner head, whereby ignition is facilitated by providing an ignition port directly adjacent an exterior terminal end portion of the electrode. The burner head has a low profile defined partly by a circumferential curved sidewall which eliminates turbulence in secondary airflow to the burner ports during high burner rates. A venturi tube providing the primary air/gas mixture to the burner and ignition is fully contained within an internal chamber of the burner head. The assembly is detachably secured to the burner opening of a range top through a twist lock engagement therewith, and is also provided with a seal to prevent spillovers from leaking between the assembly and the range top into the burner box.
