Abstract
A range includes a cabinet, defined by at least a front, side, bottom and top portions, as well as upper and lower oven cavities each having a respective gas burner assembly. At least one passageway is formed to create an airflow path enabling a portion of an ambient airflow introduced into the cabinet to reach the gas burner assemblies of the upper and lower oven cavities for combustion purposes, preferably through natural convection, while the remaining portion of the airflow passes over and cools portions of the range. In a preferred form of the invention, insulation is maintained in a desired position below a respective oven cavity by a holder through which the airflow passes to the burner assembly.
