End of settings menu without flame
When all the positions of the servomotor have been determined according to the required
settings, it is then possible to move on to the next section for commissioning - "Setting the flame".
To do this, place the cursor in the lower part of the screen on the symbol and confirm by
pressing the button .
If it is necessary to quit the menu without saving the pre-settings, position the cursor on the
symbol
and confirm with the button .
Commissioning
Pre-setting without flame
General advice before starting the burner
Preparing the burner start-up
Before starting the burner, draw fuel oil
in using a hand pump until the filter is
completely filled. Then start the burner
by switching on the boiler regulator.
Open the bleed screw on the oil filter to
allow the oil line to bleed fully during the
pre-ventilation phase. The negative
pressure must not fall below 0.4 bar.
Close the bleed screw when the filter is
completely filled with fuel oil and fuel oil
is flowing out without bubbles.
Optimising combustion values
Optimum combustion values can be
achieved by adjusting the position of the
baffle plate (dimension
Y ) if necessary.
Doing this can have an effect on starting
characteristics, pulsation and
combustion values. Any reduction in
dimension
Y increases the CO
2
value.
However, starting characteristics
become harsher.
Compensate for the change in airflow if
necessary by adjusting the air flap
position.
Precautions: To avoid condensation,
observe the minimum required flue
gas temperature specified by the
boiler manufacturer and comply with
the requirements for flue gas ducts.
If dimension Y needs to be corrected
again when the 2
nd
stage is adjusted, it
will be necessary to check the
adjustment values for the 1
st
stage.
Risk of air blast!
Continuously check CO, CO
2
and
soot emissions when adjusting.
Optimise combustion values if CO is
present. The CO level must not
exceed 50 ppm.
Function check
Flame monitoring must be checked for
safety as part of initial commissioning
and also after servicing or if the system
has been out of operation for any
significant period of time.
- Start attempt with the flame detection
cell obscured:
at the end of the safety time,
the control unit must switch to
malfunction mode!
- Start-up with the flame detection cell lit
up: the automatic combustion control
unit must switch to malfunction mode
after 10 seconds of pre-ventilation.
- Normal start; if the burner is in
operation, cover the flame detection
cell: the automatic combustion control
unit must switch to malfunction mode
after a restart and the end of the safety
time
