A:Answer Hi - Thanks for viewing our GE® Gas Range JGBS30REKSS! The BTU (Natural Gas) ratings are as follows: Left Front 9,500, Left Rear 9,500, Right Front 13,000, Right Rear 5,000, Bake 18,000, Broiler 18,000 (Total: 73,000 BTU). If you need venting, check out GE® 1.6 Cu. Ft. Over-the-Range Microwave Oven JVM3160RFSS (Stainless/Black). Two-speed, 300-CFM venting system removes smoke, steam and odors. We hope this is helpful. Keep in touch! SUE@GEA
