When it comes to getting that steakhouse quality steak off of your backyard gas grill, its simply not possible without an infrared burner. Installs in less than 1 minute, this infrared sear zone burner (IRB-18) replaces the standard stainless steel burner in your American Outdoor Grill L-Series Grill. Use your infrared searing burner for a variety of foods - fish, steaks, vegetables, fajitas and more. Typical stainless steel tube burners reach upwards of 500 degrees, this infrared searing burner however, gets up to 1,000 degrees. The IRB-18 only fits the AOG L-Series Grills and does NOT fit any other model and brand of grill.
