The NGMP655UC was a Benchmark 36 inch gas cooktop with five sealed burners and a very substantial 59,500 BTU total – the sort of output that turns a domestic kitchen into something closer to a restaurant line. Cooktops in this class demand matched ventilation and a gas supply capable of delivering the flow, and a common finding on older high-output installations is a supply line sized for a smaller appliance, which shows up as burners that lose pressure when several are running together.
