A number of heated nozzles are seated in each plate with the nozzles in one plate extending in an opposite direction to the nozzles in the other plate. The nozzles in the one plate are held in place by the manifold being secured to that plate. The nozzles in the other plate each have retaining apparatus to hold them in place during assembly and disassembly. Each nozzle retaining apparatus has a main body with a screw opening therethrough and an elongated pin extending laterally therefrom. The pin extends into a hole in the nozzle and a screw extending through the screw opening in the main body is tightened into a hole in the manifold retainer plate to secure the nozzle in place during assembly and disassembly of the manifold retainer plates.
