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 overtighten.
Check Electrode Settings
Slide the secondary adjusting plate (item
f
)
completely 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 left on the primary adjusting plate (item
g
) and
fi
nger-tighten acorn nut (item
d
).
Slide the completed adjusting plate assembly
over the nozzle line end. Move the plate assembly
and the nozzle line so the plate assembly
fi
ts into
position as shown in
Figure 6
.
Install the spline nut (item
b
) on the end of the
nozzle line, leaving the nut loosely placed so the
plates can be moved.
Connect the high-voltage leads from the ignition
transformer to the electrodes.

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

. Assemble the adjusting
plate assembly per the instructions in the assembly
packet.
