Abstract: A gas cooking range includes a number of energy-efficient features. The range includes an oven section in which combustion air is preheated by heated discharge gases. Panels are spaced from the walls of the oven and circulation fans are included to provide exceedingly effective airflow within the oven. A gas shutoff valve automatically controls the discharge of heated gases from the oven so that heated gases are discharged only when combustion is occurring. The range also includes a compact, rotatable oven/broiler burner unit, a smoke-free drip pan, an efficient piloted ignition, flame-containing rangetop burner rings atop which pots and pans can be supported, and a small, portable oven which can be supported atop the burner rings.
