1. To position the electrode tips in front of the face
of the nozzle and above the center line, select the
cross mark for the burner being serviced, DC (direct
current) Fig. 1 or AC (alternating current), Fig. 2.
You will be setting only one of the tips. After setting,
proceed to Step 3. Be careful not to scratch the
nozzle face.
DC burner F head settings are set by aligning the
electrode tip with the (1/4”) cross mark shown in

2. AC burner F head settings are set by aligning the
electrode tip with the (5/16”) cross mark shown in
Fig. 2.
3. To set the electrode tip gap (5/32”), place the
gauge so that the tip (set in Step 1 or 2) is on one of
the tip gap marks in Fig. 3 (top view). Adjust the
remaining tip to the other mark.

4. To check that the nozzle is approximately
centered with the head inside diameter, place the
gauge in the head and note the gauge center mark
location with respect to the nozzle center. Rotate
the gauge and check several positions (see Fig. 4).

5. The “Z” dimension is important because it locates
the nozzle for the precise relationship with the
combustion head. To set the “Z” dimension for F
heads, position the gauge as shown in Fig. 5 and
loosen the nozzle line electrode assembly so that it
can be moved forward or backward in the air tube
until the nozzle becomes flush against the gauge.
Tighten the nozzle line escutcheon plate screw to
lock this “Z” dimension securel
