Beckett manual Initial Head Position, CF1400 Initial Indicator Adjustment Plate Settings

Section: Prepare the Burner for Start-up

Initial Head Position

The indicator plate assembly (item e) markings correspond to head position settings (Figure 16).

○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 Tables 4a and 4b for the desired firing rate and burner (high-fire).

○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).
