Abstract

A glowing wire type electric lighter or ignition system for a burner assembly in a gas heated stove having a vitreous ceramic cooking plate is provided. The system incorporates a direct warning indication not only that the associated burner assembly is "on" or "off", but also that the heated zone region of the cooking plate over such burner assembly remains too hot to be safely touched after such burner assembly has been switched off until such heated zone region has cooled to a predetermined harmless temperature.
