Pre-setting without flame
General advice before starting the burner
End of the setting without flame menu
When all the ventilation speed setting positions have been determined according to the required
presetting, 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 press the
key.
If it is necessary to quit the menu without saving the pre-settings, position the cursor on the
symbol
and confirm with the
key.
Preparing the burner start-up
Before starting the burner, draw 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. In this situation,
the vacuum pressure must not exceed
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
If required, optimise the combustion
values by setting the ventilation speed or
pump pressure.
For 1st stage and 2nd stage, the C02
level obtained must be between 13.0% -
and 13.5%. To optimise burner start-up,
the ignition speed can be reduced to a
value which corresponds to a CO2 level
of between 14% and 14.5% (inclusive).
Warning: To avoid condensation,
observe the minimum required flue
gas temperature which complies with
the boiler manufacturer's
instructions and with the
requirements for flue gas ducts.
Risk of deflagration
Continuously check CO, CO
2
and
soot emissions when adjusting the
output of the burner. Improve
combustion values in the event of CO
emissions. The CO level must not
exceed 50 ppm.
Function check
Flame monitoring must be checked to
ensure that it is fully functional as part of
initial commissioning and also after
servicing or if the system has been out of
operation for any significant period of
time.
- Starting attempt with flame detection
cell obscured:
at the end of the safety time, the
control and safety unit must switch to
malfunction mode.
- Start-up with the flame detector cell lit:
after pre-ventilation, the control and
safety unit must switch to malfunction
mode.
- Normal start-up; if the burner is
operational, the flame detection cell
should be obscured: after restarting
and at the end of the safety time, the
control and safety unit must switch to
malfunction mode.
