Instruction Manual – Model CF1400 Oil Burner

Prepare the burner for start-up - continued

❏Z dimension

•Should be set per these instructions (see page 7). The top acorn nut (Figure 11, item d) should never be loosened once the Z dimension is initially set.

❏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 corre- sponds to the initial head setting given in Table 4 for the desired firing rate.

•Figure 11 shows a typical example, with a head setting of

5.

•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 firing 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 firing rate.

•This initial setting should be adequate for starting the burner. 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 fine- tuning the air settings.
