RECOMMENDATIONS TO PROPERLY SET THE GEARED MOTOR
The geared motor is set upon testing as follows:
CAM V (2 Stage) : is set on approx 90°-120°
CAM IV (1 Stage) : is set on approx 25°÷50°.
CAM II-III (MV1-MV2): is set in such a way that the 2nd stage valve opens when the air
shut-off valve is at 60°÷80°.
Changes to this calibration during installation are legible even when the burner is in
operation by acting on the adjusting screws of the cams.
Tightening the screws increases the angle and positioning of the cams.
