Mount the burner

Protect the Air Tube From

Overheating

Overheating could cause damage to the air tube and other combustion components lead- ing to equipment malfunction and impaired combustion performance.

yThe end of the air tube must not extend into the com- bustion chamber unprotected unless it has been facto- ry-tested and speciﬁed by the appliance manufacturer.

yPosition the end of the air tube ¼” back from ﬂush with the refractory inside entry wall to prevent damage from overheating.

Mount ﬂange(s) on air tube

yThis section does not apply to burners with welded ﬂang- es.

yDo not install air tube on burner.

yFor non-pressure ﬁring ﬂange, refer to Figure 3: Install gasket (item a) and ﬂange (item d). Ignore the next paragraph.

yFor pressure-ﬁring ﬂange, refer to Figure 3: Slide gasket (item a) onto the air tube, making sure the top of the air tube is up. Pre-drill holes in the pressure ﬁring plate (item b) to match the appliance studs. Slide the pressure ﬁring plate (item b) and ﬂange (item d) onto the air tube as shown. Wrap ceramic ﬁber rope (item c) around the air tube and press tightly into the inside diameter of the ﬂange (item d).

ySlide the air tube (item e) into position in the appliance front. Tighten the ﬂange-mounting-stud nuts. Set the insertion of the air tube so dimension G is ¼” nominal.

yPitch the air tube at 2° from horizontal as shown and secure the ﬂange to the air tube. See Figure 2.

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.

Check electrode settings

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 4. Verify that the oil tube assembly and electrodes are in good condition, with no cracks or dam- age.

Install nozzle line assembly

y Insert the nozzle line assembly into the burner air tube. Reference Figure 5.

y Slide the secondary adjusting plate (Figure 6, 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).

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