AbstractA self-cleaning gas-fueled oven for cooking with a flameholder and door which permit self-cleaning at temperatures exceeding 900° F. The flameholder has a grille divided into two opposed, substantially flat portions, each of which contains an array of ports of two distinct sizes. The smaller-sized ports are tapered, increasing in cross-sectional area in the direction of gas flow through the grille. The oven door has a lip extending substantially perpendicularly from the door's sidewalls so as to overlap the periphery of the door's inner panel.
