  • Method of making a tube burner for cooking apparatus
    Patent number: 5406703
    Abstract: A cooking-type elongate bar burner having a plurality of gas flow apertures and a top surface is defined in part by a stiffening ridge and by a pair of laterally extending flanges. The apertures are beneath the flanges and thereby substantially protected from grease clogging. The burner is roll formed of a single piece of sheet material and is configured to directly accept a gas flow control valve. Also a unique "intra-burner" cross-over ignition arrangement and a method for making the new burner by roll forming are described.
