Adjustment by the Siemens SQL33.. actuator
1
with the electrical panel open, prime the oil pump acting directly on the related contactor (see next picture): check the pump motor
rotation (see "Fan-pump motor direction" on page 10) and keep pressed for some seconds until the oil circuit is charged;
2
bleed the air from the M pressure gauge port (Fig. 21) by loosing the cap without removing it, then release the contactor.
3
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.
4
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) - see chapter "OPERATION".
5
Start the burner up by means of the thermostat series and wait until the pre-purge phase comes to end and that burner starts up;
6
the burner starts up with the actuator on the ignition position, set it to the MAN (manual mode), by the MAN/AUTO selector (ignition
position= read on the air damper index ID);

7
disconnect the TAB thermostat removing the wire from the terminal no. 6 or by setting MAN on the RWF40 modulator or by setting
0 by means of the CMF switch (only for fully-modulating burners);
8
set the actuator to the manual mode (MAN) by means of the MAN/AUTO switch (see next pictures).
9
manually drive the adjusting cam SV to the high flame position and set the actuator to the AUTO mode (by means of the related
switch - see picture) to lock the adjusting cam.
