Output on the NGMP655UC is closer to a restaurant line than a domestic kitchen. This Benchmark gas cooktop, 36 inches wide with five sealed burners, was rated at 59,500 BTU overall. Bosch has discontinued it, and its US page confirms it is unavailable.
Cooktops of this class need ventilation matched to the heat and a gas supply that can deliver enough flow. In older high-output installations we often find the supply line was chosen for a smaller appliance. Owners notice burners that fade whenever several are lit at the same time.
The cause is therefore often outside the cooktop. Heavy grates and intense heat also wear the enamel faster than on a modest model. We begin a visit by watching the burners together, since that is when a supply problem shows, then examine the grates and the hood. Anything involving the gas supply is handled with a written price first.
Yes. We often meet it in older high-output kitchens whose gas line was chosen for a smaller appliance. A gas professional should assess the line, and we can see how the burners behave under load.
If the burners are fine alone but lose strength when several run together, the supply is a likely cause. A qualified gas professional should evaluate and change the line, since that work is outside the cooktop itself.
Yes. Burning this much gas releases heat and moisture, and a hood should be matched to it. Without enough ventilation, the kitchen gets hot and surfaces collect moisture.
