Southbend Ultimate Series 60" freestanding gas range, model 4603AD_NG, is a commercial natural-gas unit with a convection oven base and a standard oven base, built for high-volume line cooking and baking. It has ten 33,000 BTU star burners for a total 407,000 BTU, a 60.75" wide floor footprint, and needs 120V/3PH power for the convection motor and ignition, so it fits full-service kitchens that want a heavy-duty range-plus-oven package rather than a compact cookline unit. Standout details include stainless front and sides, removable cast-iron grates, standing pilot top burners, battery spark ignition on the oven bases, a front manual gas shutoff, and a factory-installed regulator; the standard oven fits full-size pans, while the convection oven adds 3 racks and 175°F–550°F control.
