Mount air tube to burner

yInsert the air tube into the burner housing. Carefully align the the four screw holes.

yAttach the air tube to the burner using the four provided screws.

Install nozzle

yInstall the oil nozzle in the nozzle adapter. Use a 3/4” open-end wrench to steady the nozzle adapter and a 5/8” open-end wrench to turn the nozzle. Tighten securely but do not over-tighten.

Maintain Electrode

Speciﬁcations

Failure to properly maintain these speciﬁcations could cause ignition malfunction, puff-back of hot gases, heavy smoke, asphyxiation, explo- sion and ﬁre hazards.

yAdjust the electrode gap and position in relation to the nozzle to the speciﬁcations shown in Figure 4.

yCheck, and adjust if necessary, the critical dimensions shown in Figure 5. Verify that the oil tube assembly and electrodes are in good condition, with no cracks or damage.

Install nozzle line assembly

yInsert the nozzle line assembly into the burner air tube. Reference Figure 6.

ySlide the secondary adjusting plate (Figure 7, item f) com- pletely to the left on the indicator adjusting plate (item e). Finger tighten acorn nut (item c) to secure the two plates together. Slide both plates completely to the right (Indica- tor Plate will read 0). Tighten fastener (item d).

yInstall the spline nut on the end of the nozzle line, leaving the nut loosely placed so the plates can be moved.

Set dimension Z

yLoosen fastener c in Figure 7. Slide the nozzle line and

plate assembly until dimension Z in Figure 6 is:

CF500 - 1-9/16” ±1/16” CF800 - 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 (item c).

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

yBefore proceeding, check dimension Z once again. Loos- en acorn nut c if necessary to reposition the nozzle line. Once dimension Z is set, do not loosen the acorn nut (item) c again. Note that for the setting of fastener d, refer to Initial Head Position procedure on Page 11.

Insert burner

yPosition 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 Figure 4.

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