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

○Loosen acorn nut (item d) in Figure 6. Slide the nozzle line and plate assembly until dimension Z in Figure 6 is:

CF2500A/CF2500 = 1-3/4 ±1/16” CF3500A (tube KM) = 2-5/8” ±1/16” CF3500A (tube KR)= 3-9/16” ±1/16”

○When dimension Z (from end of air tube to flat area of front face of head) is correctly set, tighten acorn nut (item d). Verify that the adjusting plate assembly is properly seated in the groove.

○Attach the oil line from the oil valve to the nozzle line end. Tighten securely.

○Before proceeding, check dimension Z once again. Loosen acorn nut (item d) if necessary to reposition the nozzle line. Once dimension Z is set, do not loosen acorn nut (item d) again.

Insert Burner

○Position the burner in the front of the appliance and loosely tighten the nuts on the mounting studs. The burner should be pitched downward 2° as shown in Figures 3 and 4.

○See Figure 8. Install the pedestal support kit (recommended) by attaching the 3/4” NPT flange (item a) to the bottom of the burner using the (4) #10 screws provided. Cut and thread (one end only) a 3/4” pipe nipple (item b) with length 11 inches less than dimension D in Figure 8. Thread the pipe into the flange.

○Secure the burner to the appliance by tightening the nuts on the burner flange mounting studs.
