  • Method of coating a gas range top burner
    Patent number: 4009302
    Abstract: A burner assembly in which various elements are joined in a manner which ensures gastight integrity of the assembly. A porcelain-coated base plate is formed of a pair of overlying steel sheets with integral embossments defining air-gas ducts to burner heads mounted on the base plate and defining ignition tubes for conducting a flame from a pilot housing to the burner heads. The air-gas ducts are sealed by establishing a pressurized flow of a slurry of ceramic frit therethrough, which is effective to coat the full interior of the ducts and close any crevices formed between the sheets. The burner head elements are arranged to provide metal-to-metal sealing engagement with peripheral edges of apertures in the base plate sheets which are characteristically free of porcelain enamel coating. An annular embossment on one of the sheets is preloaded by deflecting it toward the other sheet during assembly of the burner head elements.
