Abstract
A more uniform heating of a griddle surface of a gas-fired cooking device is provided by a plurality of heating chambers disposed below the griddle surface, with each of the heating chambers heated by at least one naturally fed gas burner. A portion of the hot combustion gases rise into upper zones associated with each heating chamber that have relatively low average front-to-back air flow therein. The upper zones have sidewalls and downwardly extending dam walls that cooperate to create the low flow zones beneath the griddle surface. The relatively low flow rates within the low flow zones allow a more uniform layer of hot combustion gases to be formed along the underside of the griddle surface, thereby more evenly delivering heat to the griddle surface. There may be two or more such heating chambers.
