Start-up
Incorrect start-up makes the manufacturer's guarantee for the
unit void. If you have questions, please contact our Technical
Customer Service.
5.1
Initial start-up
After the ROTEX GCU compact has been erected and fully con-
nected, it can be put into service by skilled staff.
5.1.1 Requirements
–
The ROTEX GCU compact is fully connected.
–
The burner trim is closed and is sealed tight.
–
The heating and hot water system are filled and charged with
the right pressure.
–
The storage tank is filled to the overflow point.
–
The control valves of the heating system are open.
5.1.2 Checks before start-up
Ɣ
Check all connections for leakage.
Ɣ
Check all the items in the enclosed checklist (see section 5.2
- Before start-up). Log the test results on the checklist.
Only when
all items
on the checklist can be answered with
Yes
should the ROTEX GCU compact be put into service.
5.1.3 Start-up
1. Open the gas stopcock.
2. Switch on the mains switch. Wait for the start phase.
–
In case of starting problems, see chapter 10.
3. Configure the heater system from the RoCon BF control.
–
For setting and explanations, see the enclosed operating
instructions "RoCon BF Control" -> chapter "Initial start-
up".
–
Enter modified setting values in the corresponding table in
the operating instructions of the RoCon BF control.
4. First
automatic calibration
:
Ɣ
From the RoCon BF control, select the programme
[Emission Measurement] ->
[Full Load]
(see chapter 15.2),
but do not confirm
.
–
Make sure heat can dissipate into the heating network
during the calibration.
–
In the event of burner starting problems, see
chapter 7.3.4.
Î
Automatic calibration of the GCU compact and adaption
of the gas valve complete.
Î
Calibration and adaption are complete 2 minutes after the
burner symbol
appears in the display. GCU compact
runs under full load.
Ɣ
End programme [Emission Measurement].
Î
Burner blower switches off.
Ɣ
After the burner blower has come to a stop, switch off the
mains plug on the boiler control panel.
Î
GCU compact switches off.
Ɣ
Wait 20 seconds before switching the mains switch on
again. Wait for the start phase.
5. Second
automatic calibration
and
performance of flue gas
measurement
:
Ɣ
From the RoCon BF control, select the programme
[Emission Measurement] ->
[Full Load]
(see chapter 15.2),
but do not confirm
.
–
Make sure the heat can dissipate into the heating network
during emission measurement.
–
In the event of burner starting problems,
see chapter 7.3.4.
Î
Automatic calibration of the GCU compact and adaption
of the gas valve complete.
Î
Calibration and adaption are complete two minutes after
the burner symbol
appears. GCU compact runs under
full load.
Ɣ
Use the glue gas analyzer 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 further measures are required.
b) If the O
2
/CO
2
concentrations lie outside the permissible
values:
Î
Carry out a 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.
Ɣ
Document the measured values in the "Installation certifi-
cation" and in the operating manual.
WARNING!
A ROTEX GCU compact that is installed or started in-
correctly may not operate properly and is dangerous
for the health and safety of individuals.
Ɣ
Only heating engineers, authorised and trained by
gas and energy supply companies are allowed to
start up the ROTEX GCU compact.
CAUTION!
A ROTEX GCU compact not put into operation
properly can lead to damage to property and the envi-
ronment.
Ɣ
Observe the regulations in VDI 2035 in order to
avoid corrosion and deposits.
Ɣ
Measures for desalination, softening or hardness
stabilization are necessary, if the filling and top-up
water has a high total hardness (>3 mmol/l - sum
of the calcium and magnesium concentrations,
calculated as calcium carbonate).
–
We recommend Fernox scale and corrosion
protection agent
KSK (
15 60 50)
.
Ɣ
During the plant operation, the water pressure at
the manometer (green area) must be checked at
regular intervals. If necessary, readjust by topping
up.
