Pre-setting without flame
Setting is carried out in 2 phases:
- pre-adjustment without flame
- setting the flame, to fine tune the
settings based on the combustion
results
When the burner is switched on, the
control unit displays the screen below.
Important
At this point, no setting position for the
servomotor has been defined, therefore
the burner cannot be started under
these conditions.

or
, the value will scroll quickly up
or down.
- Confirm the new value using the button . The value stops
flashing.
N.B.:
It is possible to set different positions within a large range of
values. However, for safety reasons, the control unit enforces
a minimum interval of 2° between the different positions
(except between the ignition position and the 1
st
stage).
The control unit then opens
the settings mode. The screen
displays the factory pre-
settings for the different
positions of the air flap (here
for example: for a VG3.290 D).
The following positions for the
air flap are presented:
- ignition position (when the
menu is opened, the curser
goes to this position)
- position of the air flap during
the 1
st
stage
- position of the air flap when
the 2
nd
stage fuel oil valve is
opened
