Abstract
A cooktop appliance includes a top panel. A gas burner assembly includes an annular burner body positioned on the top panel at a top surface of the top panel. The annular burner body defines a central combustion zone. The annular burner body also defines a plurality of flame ports at the central combustion zone. Gaseous fuel is flowable from a fuel chamber within the annular burner body into the central combustion zone through the plurality of flame ports. The gas burner assembly further includes features for direction the gaseous fuel into the fuel chamber of the annular burner body. The annular burner body is open at the central combustion zone such that the top panel is exposed through the annular burner body at the central combustion zone.
