7.Check/Adjust Zero Calibration for older style Head/Air Adjustment Mechanism. Refer to Figure 5a.

a.Loosen the splined nut and lower acorn nut approximately one turn. (DO NOT loosen the upper acorn nut. This is used only for setting the zero adjustment.) (See Figure 5a.)

b.A 5/16” nut driver or ﬂat blade screwdriver can be used to turn the adjustment screw for head/air setting.

8.Check/Adjust Zero Calibration for newer style Head/Air Adjustment Mechanism. Refer to Figure 5b.

a.Slightly loosen the zero setting acorn.

b.Turn the screw until the reading is set to zero. (Mid-point of pointer should line up with zero.

c.Turn the air adjustment screw counterclock- wise to adjust the plate with the pointer to the zero position.

d.Slide the nozzle line assembly forward until the retention head engages the ﬁxed stops in the retention ring at the end of the air tube.

e.Tighten the zero setting acorn nut.

f.The rear door must be closed. The adjustment screw may now be turned clockwise to adjust the head/air setting.

g.Turn the adjusting screw to a setting 1/2 num- ber lower than the proper setpoint as indicated in Tables 3a and 3b. Then turn the adjusting screw counterclockwise to the proper setting.

h.Tighten the spline nut after the head/air setting has been adjusted.

NOTICE

The NX burner has a reduced diam- eter air tube, precision-designed air throttle cup and combustion head for improved performance. This design provides very accurate control of the air/fuel ratio, but the light reaching the cad cell through small holes in these components is limited. Be- cause of this, the average cad cell resistance may be higher than conventional burners with larger openings.

NOTICE

Use factory-set or manufacturer’s recommended Head/Air Setting for ‘Starting the Burner and Set- ting Combustion’. The Head/Air Settings shown in Figures 3, are provided for reference purposes and represent a general range of rates and settings. Individual ap- pliances, vent systems, and ﬁeld conditions will impact the overall burner set up required for satis- factory combustion performance.
