ROTEX GCU compact -
5 x Start-up
6. In the programme [Emission Measurement] select the setting
[Base Load] (see chapter 15.2), but do not confirm.
– Make sure the heat can dissipate into the heating network
during emission meas
urement.
Ɣ Use the flue gas analyser to check the burner settings and
compare them with tab. 5-1 to tab. 5-3.
a) If the O
2
/CO
2
concentrations lie within the permissible
values:
Î No additional measures are required.
b) If the O
2
/CO
2
concentrations lie outside the permissible
values:
Î Carry out 100% calibration and adjust the [Drop Io-base]
in such a way that the setting range is reached (see
chapter 7.3.4) and repeat the measurement from step 5.
Ɣ Document the measured
values in the "Installation certifi-
cation" and in the operating manual.
7. End programme [Emission Measurement].
8. Set manual mode from the RoCon BF control (see operating
instructions "RoCon BF Control").
9. Check the resistance in the flue gas line (see chapter 4.5).
5.1.4 After start-up
Ɣ Mount the sound insulation hood (see chapter 4.4.3).
Ɣ Check all items on the "Checklist after start-up" (see
section 5.2).
Ɣ Log the test results on the checklist
.
Only when it is possible to answer all items on the checklist
with Yes, i
s it allowed to hand over the ROTEX GCU compact
to the operator.
CAUTION!
The firing unit is programmed to take into
account the ageing of th
e components.
A 100 % calibration of the firing unit can have
a negative impact on th
e above even if the
exhaust setting values (tab. 5-1 to tab. 5-3) are
adhered to.
Ɣ Only carry out a calib
ration of the firing unit
when the exhaust setting values are not
adhered to, or when a mechanical change
was carried out, e.g. by replacing the
component with original ROTEX spare
parts.
