Why is my oven smoking when I'm grilling? How can I fix it?

"Reasons: Food placed too close to heating elements, incorrect rack position, excessive fat content in food, failure to use the included drip pan, grease residue inside the oven;
Solutions:
Adjust rack position (place meat on racks 3-5), trim excess fat from food;
Use the included drip pan (with grid to allow grease to drip through);
Clean the oven promptly after grilling to remove grease residue."
