CF1000 Burner Manual
Section: Prepare the Burner for Start-up
Z Dimension
Should be set according to the instructions given
previously in this manual. The top acorn nut (Figure 16,
item d) should never be loosened once the Z dimension
is initially set.
Adjusting Plate Assembly
Make sure spline nut (item b) and bottom acorn
nut (item c) are loose (Figure 16).
Initial Head Position
(See Figure 16)
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 16 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
(See Figure 17)
Loosen the screw holding the air adjusting plate
(item L). 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 stop tab on
the air adjusting plate is in line with 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.
