Abstract:
A gas burner assembly comprising:a burner head including a side wall provided with a plurality of circumferentially spaced burner ports and an enlarged igniter aperture, said burner head being adapted to contain a combustible air/gas mixture therein with the combustible mixture being directed to flow through the plurality of burner ports;an electrode extending within the burner head and including an end portion projecting, at least partially, through the igniter aperture; andan electrical insulator including an outer peripheral surface and a bore formed diametrically inward of the outer peripheral surface, said end portion of said electrode being positioned in the bore with said insulator being located between the burner head and the electrode at the igniter aperture, said insulator further defining at least one passage extending therethrough at a position spaced diametrically inward from the outer peripheral surface, wherein the at least one passage opens into the bore and extends along said electrode and wherein a percentage of the combustible mixture is adapted to be delivered, without substantial obstruction, from within the burner head through the at least one passage of the insulator while exiting the insulator adjacent the end portion of the electrode such that a spark created at the end portion of the electrode will ignite the percentage of the combustible mixture.
