A burner head insert (20) is disposed within the cylindrical outlet end 44. The burner head insert (20) has an axially elongated annular body (22) having an axially extending inner flow passage (25) passing therethrough and a plurality of circumferentially spaced, axially extending splines (30) radiating outwardly therefrom toward the surrounding wall of the outlet end (44) of the burner tube.
