RECOMMENDATIONS TO PROPERLY SET THE GEARED MOTOR

The geared motor is set upon testing as follows:

Red cam:

is set on approx 90°-120°

Orange cam: is set on approx 25°÷50°.

Black cam:

is set in such a way that the 2nd stage valve opens when the air shut-off valve

is at 60°÷80°.

Blue cam:

is set on 0°

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.

NOZZLE HOLDER ADJUSTMENT

The special shape of the draught tube and the diffu-

ser, the position of which is adjustable even

when the burner is working, allows optimisation

of combustion parameters right across the burner

flowrate range and even in critical working conditions.

Turning the screw (17) clockwise results in the advan-

cement of the nozzle port and a smaller flow of air

around the deflector disc. Turning the screw counter-

clockwise increases the passage of air.

PUMP PRESSURE ADJUSTMENT

Pump pressure is calibrated at the factory at 10 bar for the 1st stage and 18 bar for the 2nd

stage. However, should it be necessary, pressure can be adjusted by turning the screw (P1)

for the 1st stage, and screw (P1) for the 2nd stage. To check the obtained pressure fit a pres-

sure gauge on the pressure take-off point (P).

N.B. With a scale range of up to 30 bar the working range of the pump is min 7 - max 14 bar.
