Abstract
Abstract According to the invention, a universal frame is provided for use in both high and low broiler configuration gas ranges. The range frame has a housing with an internal wall surface defining a cooking space. A gas burner is mounted in the cooking space between a main oven compartment and a broiling compartment in the low broiler configuration. Structure is provided to selectively mount a wall within the cooking space to shield the lower compartment from the heating element. The lower compartment can thereby be adapted for use as a storage compartment in a high broiler configuration. With the wall omitted, the heating element is directly exposed to the bottom compartment for broiling therein.
