Setting the pump pressure
The pump pressure should be
adjusted, and checked if necessary,
during burner commissioning and
during every service.
Adjust the pump pressure as
follows:
1. Remove the stopper on
the measurement nozzle “P”.
Remember to remove the seal.
2. Fit a suitable oil pressure
manometer here.
3. Open all oil shut-off devices.
4. Switch on the burner.
5. Set the required oil pressure
in accordance with the nozzle
size and the unit capacity.
6. Please note that the required oil
pressure of the full load stage
(DV2) must be set up before
the oil pressure of the partial
load stage (DV1) because
the DV2 pressure adjustment
can have an impact on DV1.
7. Switch off the burner after
completing the adjustments.
8. Remove the oil pressure
manometer again.
Re-fit stopper incl. seal.
Adjusting the secondary air
(nozzle fitting adjustment)
Carry out the presetting
of the secondary air as follows:
Set the nozzle fitting [2]
to the desired value with
the adjusting screw [1].
Turning to the left
(
+
)
= larger scale value
lower

Turning to the right
(
–

NOTE
Never let the pump run for
extended periods without any
fuel. Never leave the units for
extended periods with a pump
that has run dry.
ATTENTION
If the burner should carry out
a fault shut-down once again
after the start phase, then
another reset should be carried
out after a waiting period
of 5 minutes has passed.
Further reset procedures must
be prohibited as there is
a danger of deflagration.
NOTE
All values provided are only
preliminary settings and must
be adapted or calibrated in
accordance with the exhaust
gas analysis.
NOTE
The burner setting must be
checked after every change
of location and adapted
to the new environmental
conditions and atmospheric
conditions if necessary.
