The first step of assembly is to install the roll pin. This pin indexes the notched burner-end tube when inserted into the gooseneck. The holes drilled into the burner-end tube must face upward towards the top of the boiler. Their purpose is to allow any coal gas in the pipe to be vented safely into the burner pot. The clean-out wedges are loosely installed.

The shoulder bolt, set screws, and clean-out cover are installed. Properly installed, the clean-out cover will slide under the wedges in the closed position and fit snugly against the gooseneck. There will be no air entering in any of the five ports in the cover. The shoulder bolt is installed in the clean-out cover tab and is shown in this picture with the bolt head on the rear side of the cover. It's put there to protect it from damage during shipping and handling, but when the final installation is complete, the bolt head will be on the visible side of the cover and will be the lowest piece on the installed pot assembly.

A roll pin, part #82817 is installed into the air chamber as an index pin for the air tube. This pin will mate with the notched end of the air tube and hold the pot assembly, along with the two set screws, part # 81505, at a 90 degree angle to the stoker.

The burner plates (9436232K) are installed in the burner ring with six ¼ X 20 X 1 ¼” machine screws (82019) shown in the inner circle. The assembly is then bolted to the air chamber using another set of six screws. Note that the plates are concentric at their bottom. If the plates are not concentric, loosen the burner plate screws and move them until they are in a perfect circle, otherwise they will not fit into the gooseneck machining.

The gooseneck assembly is now bolted to the air chamber and secured with four allen head bolts (87085). Note the position of the gooseneck in relation to the air chamber. It may be necessary to use a rubber mallet to tap around the edges of the gooseneck to seat the bottom of the burner plates into the rope gasket in order to get the allen head bolts to engage the threads in the air chamber.
