Oil Flow Rate Settings by means of Berger STM30../Siemens SQM40.. actuator
1 Check the fan motor rotation.
2 Prime the oil pump acting on the related contactor ( CP - see next picture): check the pump motor rotation (see “Fan and pump
motors direction” on page 11) and keep pressing for some seconds until the oil circuit is charged;
3 bleed the air from the M pressure gauge port (Fig. 18) by loosing the cap without removing it, then release the solenoid starter.

4 Before starting the burner up, drive the high flame actuator microswitch matching the low flame one (in order to let the burner ope-
rates at the lowest output) to safely achieve the high flame stage.
5 Turn the burner on by means of its main switch A (see next picture): if the burner locks (LED B on in the control panel) press the
RESET button ( C ) on the control panel - see chapter “OPERATION”.
6 Start the burner up by means of the thermostat series and wait unitl the pre-purge phase comes to end and that burner starts up;
7 drive the burner to high flame stage, by means fo the thermostat TAB (high/low flame thermostat - see Wiring diagrams), as far as
fully-modulating burners, see related paragraph.
8 Then move progressively the microswitch to higher values until it reaches the high flame position; always check the combustion
values (see next steps).
