Abstract
A cooktop appliance, as provided herein, may include a top panel and a gas burner assembly positioned at the top panel. The gas burner assembly may include an annular burner body, a fuel manifold, and a thermal break. The annular burner body may be positioned at the top panel at a top surface thereof. The annular burner body may define a central combustion zone, a plurality of flame ports at the central combustion zone, and a fuel chamber upstream from the plurality of flame ports. The annular burner body may be open at the central combustion zone such that a circumferentially bounded portion of the top panel is vertically exposed. The fuel manifold may be selectively connected to the annular burner body upstream from the fuel chamber. The thermal break may be formed along the circumferentially bounded portion of the top panel below the plurality of flame ports.
