Evos technology allows independent heat adjustment across inner and outer cook surface zones for managing a wide range of menu possibilities. Heat is delivered to each burner via separate inner and outer control knobs.Edge-to-edge even surface temperatures range from 225F to 550F (121C to 288C) from the center to the outside edge without the hot spots and temperature problems prone to traditional square griddles. The burner system has a push button electronic ignition system which ignites both burners simultaneously. A stainless steel drip pan completely surrounds the underside of the cook surface catching all food debris. Separate spill over trays that contain and hold drip pan debris are concealed in front doors at right and left side of the control panel. Operating on either Natural Gas or Propane LP Gas, the Affinity 30G Cooktop is an ideal solution for creating a social cooking space with any outdoor kitchen.
