•Check Retention Head Alignment and Cad Cell Sighting (Refer to Figure 8.)

The cad cell sighting holes in the throttle cup and the retention head must be aligned to allow the cad cell to detect the flame. Make sure the stamped key in the retention head collar lines up with the keyway in the nozzle adapter when mounting the retention head. Note that in specific applications, the reten- tion head may not have a sighting hole.

• Check/Adjust “Zero” Calibration

On burners with factory-installed air tubes, the zero calibration has been factory set. Make sure the retention head (Figure 8) is securely against the stops in the retention ring when the adjustment plate pointer is at “0” (Figure 5).

If the zero calibration has not been set, perform the following procedure:

1.Install the nozzle line, with the adjustment plate assembly attached, into the burner.

2.Install and tighten the rear door to hold the air adjustment plate assembly in position.

3.Slightly loosen the upper acorn nut, the splined nut, and the lower acorn nut.

4.Turn the air adjustment screw clockwise to adjust the plate with the pointer to the zero position.

5.Referring to Figure 8, slide the nozzle line as- sembly forward until the retention head engages the fixed stops in the retention ring at the end of the air tube.

6.Tighten the upper acorn nut securely.

7.The rear door must be kept tightly closed. The adjustment screw may now be turned to adjust the head/air setting.

8.Turn the adjusting screw to a setting that is 1/2 number lower than the proper set point as indi- cated in Table 1. Then turn the adjusting screw counterclockwise to the proper setting.

9.Tighten the splined nut and lower acorn nut after the head/air setting has been adjusted.
