yInsert the nozzle line assembly into the burner air tube as in Figure 5.

ySee Figures 5 and 6. Assemble the adjusting plate assem- bly per the instructions in the assembly packet.

ySlide the secondary adjusting plate (item f) completely to the left on the indicator adjusting plate (item e). Finger tighten acorn nut c to secure the two plates together. Slide both plates completely to the left on the primary adjusting plate (item g) and ﬁnger-tighten acorn nut d.

ySlide the completed adjusting plate assembly over the noz- zle line end. Move the plate assembly and the nozzle line so the plate assembly ﬁts into position as shown in Figure 5.

yInstall the spline nut (Figure 5, item b) on the end of the nozzle line, leaving the nut loosely placed so the plates can be moved.

yConnect the high-voltage leads from the ignition trans- former to the electrodes.

Set dimension Z

yReplace the rear access door on the burner, making sure that the adjusting plate assembly is now securely in the groove.

yLoosen acorn nut d in Figure 5. Slide the nozzle line and plate assembly until dimension Z in Figure 5 is 1-3/4” ± 1/16”. When dimension Z (from end of air tube to ﬂat area of front face of head) is correctly set, tighten acorn nut d. Verify that the adjusting plate assembly is properly seated in the adjusting groove.

yAttach the oil line from the oil valve to the nozzle line end. Tighten securely.

yBefore proceeding, check dimension Z once again. Loosen acorn nut d if necessary to reposition the nozzle line. Once dimension Z is set, do not loosen acorn nut d again. For the setting of acorn nut c, refer to Page 13.
