Adjusting plate assembly (Figure 11)
 
  Make sure spline nut (item b) and bottom acorn nut (item 
c) are loose.
Initial head position (Figure 11)
The indicator plate assembly (item e) markings correspond 
to head position settings.  Slide the secondary adjusting 
plate (item f) toward the rear of the burner until the number 
on the indicator plate corresponds to the initial head setting 
given in Table 4 for the desired fi ring rate.
Figure 11 shows a typical example, with a head setting of 
6.
When the head position has been set, tighten the bottom 
acorn nut (item c) and the spline nut (item b).
Initial air settings (Figure 12)
Loosen the screw holding the air adjusting plate (item m). 
Set the air to the desired rate. (The numbers on this plate 
correspond to the approximate fi ring rate settings given in 
Table 5.)
Rotate the air adjusting plate until the lower edge of the 
pointer is opposite the number from Table 5 corresponding 
to the desired fi ring rate.
This initial setting should be adequate for starting the burner. 
Tighten the screw to secure the adjusting plate. Once the 
burner is in operation, the air setting will be adjusted for 
best performance as discussed later in this manual.
Follow the procedures given later in this manual for fi ne-
tuning the air settings.
