Abstract
An igniter electrode assembly for gas ignition of an oven burner includes a pop-in and pop-out feature that allows for the easy installation, removal, and replacement of an igniter electrode. The feature allows maintenance access to the igniter electrode without any tools or the need to disassemble the burner assembly. A bushing surrounds the igniter electrode and is held in position by set screws. Ball plungers screwed into the burner plate guide the bushing along keyways in the bushing surface. The ball plungers securely snap into recesses located at the end of the keyways. The invention allows for precision positioning of the igniter electrode tip and repeatability of positioning without having to readjust the igniter electrode or the bushing.
