Five gas hotplates two burners each on the right and left, one large middle burner (1000/2 x 1750/2700/3500 watts). Stainless steel for the surface. A black cast pan supports/grill. Premium stainless cylindrical gas knobs .The flush installation of the hob and pan supports means that pots and pans are at a lower height for improved ergonomics and safety, regardless of shape and diameter. Pots and pans can also be moved easily from one hotplate to another without lifting them. Extremely easy to clean thanks to the smooth stainless surface.
