Mount the Burner
Mount Flange on Air Tube
Note: This section does not apply to burners with welded
fl anges.
Do not install air tube on burner.
For non-pressure fi ring fl ange, refer to Figure 4:
Install gasket (item a) and fl ange (item c). Ignore the
next paragraph.
For pressure-fi ring fl ange, refer to Figure 4: 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 c) onto the air tube as shown. Wrap
ceramic fi ber rope around the air tube and press
tightly into the inside diameter of the fl ange (item c).
Slide the air tube (item d) into position in the
appliance front. Tighten the fl ange-mounting stud
nuts. Set the insertion of the air tube so dimension G
is 1/4” nominal.
Pitch the air tube at 2° from horizontal as shown and
secure the fl ange to the air tube. ○

Mount Air Tube to Burner
Remove the rear access door from the back of the
burner for improved access to the interior.
Attach the air tube to the burner with the bolts and
acorn nuts provided. The acorn nuts must go on the
outside of the burner, with the bolts inserted from the
inside.
Install Nozzle
See Figure 5. 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
○
○
Check, and adjust if necessary, the critical dimensions
P, Q, R
and S shown in Figure 5. Verify that the oil tube
assembly and electrodes are in good condition, with no
cracks or damage.
Protect the air tube from
overheating.
Overheating could cause damage to the air
tube and other combustion components
leading to equipment malfunction and
impaired combustion performance.
The end of the air tube must not extend into the
combustion chamber unprotected unless it has
been factory-tested and specifi ed by the appliance
manufacturer.
Position the end of the air tube 1/4” back from
fl ush with the refractory inside entry wall to prevent
damage from overheating. y

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