The NGM8658UC was an 800 Series 36 inch gas cooktop with five sealed burners at 42,700 BTU. A useful thing to know about any Bosch gas cooktop of this generation is where the model and serial plate lives: it is on the underside of the appliance, which means identifying the machine requires either lifting it or finding the paperwork. Photographing that plate at installation saves a lot of trouble a decade later when nobody can remember what was fitted.
