18 The low flame position must never match the ignition position that is why cam 

BF2

 must be set 20°- 30° more than the ignition position.

19 Turn the burner off; then start it up again. If the adjustment is not correct, repeat the previous steps.

As far as fully-modulating burners, see paragraph on page 30.

Light oil circuit

The fuel is pushed into the pump 1 to the nozzle 3 at the delivery pressure set by the pressure governor. The solenoid valve 2 set the
fuel immission into the combustion chamber. The part of fuel that is not burnt goes back to the tank through the return circuit. The fuel
amount to be burnt is adjusted by means of the burner actuator according to the adjustments set (see prevoius paragraph).
