To check that the nozzle is approximately centered with the
head inside diameter on FBX and F heads place gauge in head
and note the gauge center mark location with respect to the
nozzle center. Rotate the gauge and check several positions.
For NX, HLX, AF2, L and V heads, align the edge of the gauge
with the inside diameter of the head and note the location of the
gauge center mark with respect to the center of the nozzle. See
Figure 5.

To position the electrode tips in front of the face of the nozzle
and above the center line, select one of two cross marks for
the burners as shown in either Figure 2 or 3. Set one tip to the
gauge position then adjust the other to match. Electrode tip
setting reference chart is shown below. (See individual instruc-
tion manuals for more details.)
Figure 1.
F, FBX, L and V
head settings are
set by aligning the
electrode tip with
the
5/16
" cross
marks (Figure 2).
After setting pro-
ceed to 'Tip Gap
Spacing', Figure 4.
Note:
Be careful
not to scratch the
nozzle face.
Set the NX, HLX or
AF2 tip positions by
aligning the electrode
tip with the mark
shown in Figure 3.
Set the electrode tip
gap spacing (5/32”)
by adjusting the tips
to meet the two out-
side marks shown
in Figure 4. Make
sure the tips are
centered above the
nozzle by maintain-
ing the center mark
of the gauge directly
above the nozzle
centerline. (Also see
Figure 1.)
