The most powerful cooktop burner offered by Jenn-Air, the 20,000 BTU dual-stacked PowerBurner can sear, create a rapid boil, or achieve high heat for wok cooking, and can reach an ultra-low 700 BTUs that makes it possible to melt chocolate or butter without scorching. With a power output ranging from 6,000 BTUs to below 1,000 BTUs, this simmer burner gives you maximum control while simmering sauces and melting delicate ingredients like chocolate and butter. If the flame is accidentally blown out by a draft, a spark occurs that automatically re-ignites the extinguished burner. A white indicator light glows, indicating when a burner is on, providing a modern look and a convenient reminder for cooks. With an extremely low profile, you can have a minimal look —nearly flush with the countertop — for an integrated transition to the cooktop.
