This ProFire Professional Series natural gas grill features two controlled grilling zones with four 11,000 BTU stainless steel burners that push 44,000 BTUs of total cooking power on the grilling surface. The 16 gauge, commercial grade stainless steel flavor plates are self-cleaning and distribute heat evenly over the entire 525 square inch cooking surface while minimizing flare-ups. The grill is constructed of commercial grade stainless steel, and the double walled hood features a seamless design that is accented with a polished mirror finish. The 5/16 inch stainless steel cooking grates are spaced more closely together than other grill models to better accommodate small items. This ProFire grill also comes standard with a stainless steel smoker tray, dual purpose thermometer, and electronic multiple spark igniter to enhance your grilling experience. Island opening must have a floor to support the grill or the island trim kit should be purchased.
