Abstract: A gas burner for use in water heaters, boilers, cooking appliances or the like uses a ceramic cylindrical body to increase conductivity of the gas burner. The gas burner comprises a solid ceramic perforated tube and a flange arranged on one end of the tube. The burner assembly also compromises a cap arranged on the opposite end of the tube from that of the flange, wherein the tube has turn down characteristics of approximately 30 to 1. The tube is manufactured by molding a non-perforated shell within a die assembly. The non-perforated shell is then dried to a predetermined moisture content and machined with a plurality of orifices into the shell to create the burner tube for a ceramic burner assembly.
