The Evo Affinity 25G Cooktop is the perfect solution for outdoor kitchens where the emphasis is on social cooking. Foods can be prepared directly on the cooktop, and either separately or simultaneously, pots and pans may be used as in traditional stove top cooking. The 25G has a 25” (635mm) diameter black oil-seasoned steel (optional ceramic-clad cook surface available) heated underneath by inner and outer gas tube burners. Evo’s 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. See less
