DESC: SUMMIT brings classic designs and durability to apartment sized ranges, with our 20, 24, 30 and 36 inch models. These models are all made in the USA , and have much larger ovens than most competing products. Our ovens are fully porcelain, as are the tops, manifolds and burner boxes. SUMMIT ranges also have oven windows and lights, and clocks with timers. Gas models are available with sealed burners and electronic (spark) ignition, and electric models are 220 volts. Our ranges use more steel and porcelain than virtually all of the competition, and NEVER use cinder-blocks to add weight and balance, as many imported ranges do. Gas models are all convertible from natural to LP without any kits.
