ABSTRACT:
A thermally efficient gas range includes a top surface adapted to be sealed to a gas burner assembly, and a downdraft plenum adjacent the gas burner assembly adapted to draw cooking vapors, heat and the products of combustion and cooking from adjacent the surface of the range and the gas burner assembly, and a sealed, powered gas burner assembly comprising an open flame surface burner and a combined air and gas supply means adapted for connection with an air flow source and a gas flow source to provide a combustible gas/air mixture to a sealed conduit connected between the gas burner and the combined air and gas flow supply means. The combined air and gas flow supply means combines flows of primary combustion air and gas from their respective sources and controls the air flow and gas flow to provide a burning gas/air jet at each burner outlet with rapid, substantially complete combustion in a short, stable flame which is substantially immune to such outside influences as the downdraft exhaust and limits generation of CO and NO.sub.x.
