800 Series 30" Gas Cooktop

The 800 Series gas cooktop with FlameSelect® is a better way to cook with gas and delivers precision flame levels for consistent results.

Eliminate the guesswork of cooking with FlameSelect®

Introducing FlameSelect® on Bosch cooktops, an entirely new and better way to cook with gas. 9 preset power levels let you easily adjust flame level for more precise, controlled heating. Whether you’re rapidly bringing water to an intense boil or delicately melting chocolate, the numbered flame levels deliver the exact temperature every time. There’s no more hot or cold spots, just precision heating for perfect results.

Sleek Knobs with LED Indicators

Control knobs with an embedded red LED light line indicate if the burner is on or if there is residual heat.

Simmer delicate sauces with the OptiSim® Burner

The OptiSim burner design is wider and thicker which diffuses heat evenly for better flame control when simmering delicate sauces.

Dual-Flame Power Burner

Dual-flame power burner has two rings for low and high flame settings to go from simmer to sear with ease. Heat level 1-3 uses the inner ring, and 4-9 uses both rings for maximum heat.

Easy to clean, low-profile design

The low-profile cooking surface provides a timeless, streamlined look while keeping spills contained and makes clean-up easier than ever

Dishwasher-safe grates

A special enameling process allows the grates to be washed directly in the dishwasher instead of by hand for easier clean up.
