Abstract
An improved pilot burner includes an orifice plate defining a central orifice for metering a supply of gas and a gas tube. The gas tube includes a tube wall and defines a supply opening at a first end. The orifice plate is positioned within the gas tube at the supply opening, and the tube wall is crimped around the orifice plate to secure the orifice plate to the gas tube. The pilot burner also includes a burner tube having a first end for receiving a first end of the gas tube. The burner tube further includes a second end defining a flame opening. In another embodiment, a clip is used to secure the gas tube and the burner tube to a bracket.
