ABSTRACT:
A cooking appliance includes a gas burner element, at least one electric heating element and a convection airflow system having a convection fan about which is disposed the at least one electric heating element. A control unit selectively activates the gas burner, the electric heating element and the convection fan to establish a desired temperature within the oven cavity. Once established, the control unit then cycles operation of the gas burner and electric heating element to maintain the desired temperature. With this arrangement, in a start-up period during which products of combustion are highest, operation of the electric heating element aides in the combustion process to reduce emissions from the appliance, as well as causing a reduction in overall cook time.
