Mount the burner
Mount fl ange(s) on air tube
This section does not apply to burners with welded fl ang-
es.
Do not install air tube on burner.
For non-pressure fi ring fl ange, refer to Figure 3: Install
gasket (item a) and fl ange (item d). Ignore the next
paragraph.
For pressure-fi ring fl ange, 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 fi ring plate (item
b) to match the appliance studs. Slide the pressure fi ring
plate (item b) and fl ange (item d) onto the air tube as
shown. Wrap ceramic fi ber rope (item c) around the air
tube and press tightly into the inside diameter of the fl ange
(item d).
Slide the air tube (item e) into position in the appliance
front. Tighten the fl ange-mounting-stud nuts. Set the
insertion of the air tube so dimension G is ¼” nominal.
Pitch the air tube at 2° from horizontal as shown and secure
the fl ange to the air tube. See Figure 2.

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.
The end of the air tube must not extend into the com-
bustion chamber unprotected unless it has been facto-
ry-tested and specifi ed by the appliance manufacturer.
Position the end of the air tube ¼” back from fl ush with
the refractory inside entry wall to prevent damage from
overheating.

Mount air tube to burner
Insert the air tube into the burner housing. Carefully align
the the four screw holes.
Attach the air tube to the burner using the four provided
screws.
Install nozzle
Install 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

y
Adjust the electrode gap and position in relation to the
nozzle to the specifi cations shown in Figure 4.

Failure to properly maintain these specifi cations
could cause ignition malfunction, puff-back of
hot gases, heavy smoke, asphyxiation, explo-
sion and fi re hazards.
Maintain Electrode
Specifi cations
Check, 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.
