a first valve associated with the gas burner to control a gas flow to the gas burner; and
a second valve configured to controllably supply gas to the gas burner via the first valve, the second valve being automatically adjustable based on a desired temperature of the cooking chamber and an actual temperature of the cooking chamber using a capillary tube operatively connected to a bulb that is exposed to the actual temperature of the cooking chamber, the second valve being configured to meter the gas flow to the gas burner as a function of the actual temperature of the cooking chamber to which the bulb is exposed to maintain the desired temperature inside of the cooking chamber.
