A convection heating apparatus with smoke and grease management means and an improved temperature controlled gas delivery system. The apparatus includes an exterior cabinet, an interior chamber and intermediate walls disposed between the exterior cabinet and interior chamber such that an intermediate cavity is provided between the interior chamber and intermediate walls and an outer cavity is provided between the exterior cabinet and intermediate walls. The apparatus further includes a product support, preferably a conveyor, disposed in the interior chamber. A blower for circulating temperature controlled gas into said interior chamber is also provided which is in fluid communication with at least one duct (preferably a plurality) having a jet plate with orifices positioned to direct temperature controlled gas toward the product support. A second blower is provided for circulating air through the outer cavity and intermediate cavity to cool the exterior cabinet walls and interior chamber walls. An improved air delivery duct is provided having a dual taper resulting in uniform distribution of the temperature controlled gas to a food product. An air filtering system is also provided comprising a perforated filter plate or louvers and/or catalytic converter disposed in the temperature controlled gas return path.
