Abstract: A cooking oven having an electric heating element in the bottom for baking, warming and high temperature-self cleaning, and an infrared gas broiler in the top of the oven. The infrared gas broiler is supplied with a fuel gas/air mixture from a venturi tube that uses the stream of fuel gas to draw clean air into the oven from outside the oven. A flue duct is provided in the top rear of the oven for the discharge of the combusted gases but no other opening is provided, such as for secondary air that is normally required for a gas oven. The venturi tube assembly creates a fuel gas/air mixture that contains 100% of the air necessary for full combustion of that gas and a positive pressure for distributing the gas/air mixture through ceramic radiants for combustion to heat the radiants to a temperature for producing the infrared light waves.
