A multi piece gas burner assembly that is machined or cast and having a burner base that contains holes for primary air where the hole dimensions do not exceed the height of a jet mounted therein. The burner base is fastened onto an appliance. The burner head rests upon a boss on the burner base and has a tube that directs a flammable gas-air mixture from the burner base into a cavity created between the burner head and the burner cap. The burner cap rests upon the burner head and contains an outer edge that is turned downwards in order to allow fluid to drip away from the flame. A groove is cut into the burner cap just inside the down turned outer edge and provides a location for a support flame. The location of the groove prevents fluid and dust from collecting inside the groove. The groove captures the flammable gas-air mixture, which provides a constant ignition source for the gas-air mixture through slots in the burner cap when ignited.This improved version of a multi piece gas burner assembly has simplified parts and has locating bosses moved to the outer edge of the gas burner assembly for simpler fixing of the components. Also, the burner cap now overlaps and rests on the burner head, which is simpler than using locating detents. Also, a multiplicity of larger and smaller holes drilled through an annular burner ring attached to the burner head improve the operation of the burner in extremely cold temperatures.
