Abstract: A sealed gas surface burner having a ring portion that sits on the main top around the periphery of the main top aperture through which the burner extends. The ring portion forms a substantially liquid tight seal with the main top, and has a raised shoulder to prevent liquid on the main top from running down through the burner aperture in the main top. A burner body is supported by the ring portion at spaced intervals to provide passageways from underneath the main top. A cap is supported by the burner body thereby forming a chamber which receives a mixture of gaseous fuel and primary combustion air. The mixture issues from ports in the side wall of the burner body where it is ignited to produce a cooking flame. Secondary combustion air is drawn from underneath the main top through the passageways in the burner to support combustion of the flame.
