Adjusting the air flap
The air flap is opened or closed
until the soot pattern has an
oil-free colour, soot “0 – 1” and
the CO
2
value is 12 - 14 %. When
carrying out the settings, keep in
mind that the soot level may climb
and oil may appear in the soot
pattern if there is significant excess
air.
If the flame should give off
sooty smoke or break away with
a fully opened air flap, reduce
the pressure behind the baffle
plate using the adjusting screw.
Adjusting the air volume
“stage 1”
Blue shift lever
Disconnect the 4-pin plug
connection (thermostat stage 2).
Rotate the
orange shift lever
“air volume stage 2” and black
shift lever “solenoid valve 2”
in a clockwise direction to such
an extent that neither switching
cam is pressed in order to ensure
that adjustments to the switching
cam “air volume stage 1” are not
hindered.
Stage 1, less air:
Move the blue shift lever in
an anti-clockwise direction
to a smaller opening angle.
If the burner is operational,
the actuator will rotate
automatically.
Stage 1, more air:
Move the blue shift lever in
a clockwise direction to a larger
opening angle.
If the burner is operational,
the actuator will rotate
automatically.
Adjusting the switching point
“solenoid valve 2”
Black shift lever
Rotate the shift lever for “solenoid
valve 2” back in an anti-clockwise
direction and place the switching
point “solenoid valve 2” just
behind the switching point “air
volume stage 1”. The switching
point “solenoid valve 2” will now
work between the settings “air
volume stage 1” and “air volume
stage 2”.
Adjusting the air volume
“stage 2”
Orange shift lever
Rotate the shift lever for “air
volume stage 2” back in an anti-
clockwise direction and place the
switching point for “air volume
stage 2” behind the switching
point “solenoid valve 2” in line
with the burner output. Re-
establish the 4-pin plug connection
(thermostat stage 2). The actuator
moves to the position “air volume
stage 2” via “solenoid valve 2”.
Stage 2, less air:
Once the calibration of stage 2
is complete, fine-tuning of the
1st stage may only be carried
out using the blue adjusting
lever or the pump pressure for
the small load.
Changes to the nozzle fitting
or the air inlet nozzle will
eliminate the settings for
the 2nd stage
Ensure that the switching cam of
“solenoid valve 2” cannot under
any circumstances be pressed
before the switching cam “air
volume stage 1” , otherwise
“solenoid valve 2” in the area
“air volume 1” will open and
the burner will operate with
a significant air deficiency.
IMPORTANT
IMPORTANT
Move the orange shift lever in
an anti-clockwise direction to
a smaller opening angle.
Switch the burner back to stage
1 briefly. After re-activating
stage 2, the actuator rotates to
the modified air volume.
Stage 2, more air:
Move the orange shift lever
in a clockwise direction to a larger
opening angle.
If stage 2 is operational,
the actuator will rotate
automatically.
The actuator or the air flap
must not be subjected to
mechanical contact at any
point or this will result in
damage to the actuator.
