Abstract: The invention is directed to cooktop apparatus wherein a cooktop panel is seated in a frame and is made of glass ceramic, glass or ceramic. The cooktop panel has a cutout for accommodating an atmospheric gas burner in the cooktop panel. A component assembly holds the gas burner in the cooktop panel and the component assembly includes a collar annularly overlapping a portion of the panel in the region of the cutout. The collar has an inner region defining an edge which, in turn, defines a first abutment for engaging the gas burner. A resilient metal element is attached to the gas burner and extends outwardly from the gas burner to engage the panel on the lower side thereof. The lower side of the panel defines a second abutment against which the resilient metal element applies a force F to hold the gas burner on the panel via the collar and the resilient metal element. A seal is sandwiched and clamped between the collar and the panel thereby preventing any spillage from reaching the frame through the cutout.
