5 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
Once the ROTEX GCU compact has been fully installed and con-
nected, it can be started up by suitably trained staff.
5.1.1 Requirements
– The ROTEX GCU compact is fully connected.
– The cover of the heat cell is closed and 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 heating system's control valves are open.
5.1.2 Checks before start-up
●
Check all connections for leakage.
●
Go through all items of the checklist (see chap. 5.2 - Before
start-up). Log the test results on the checklist.
Only once
all points
on the checklist can be answered with
yes
may the ROTEX GCU compact be started.
5.1.3 Start-up
1. Open the gas stopcock.
2. Switching on the mains switch. Wait for the start phase.
– In the event of starting problems, see chap. 10.
3. Configure the heating system on the RoCon BF controller.
– For configuration and explanations, see the enclosed
operating instructions "RoCon BF controller" ->
chapter "Initial start-up
"
.
– Enter modified setting values in the corresponding table in
the operating instructions for the RoCon BF controller.
4. First
automatic calibration
:
●
On the controller RoCon BF select the program [Emission
Measurement] ->
[Full Load]
but
do not confirm
.
– Make sure that heat can dissipate into the heating network
during calibration.
– In the event of burner starting problems, see chap. 7.3.4.
Automatic calibration of the GCU compact and adjust-
ment of the gas valve complete.
Calibration and adjustment are complete 2 minutes after
the burner symbol
appears on the display.
GCU compact runs at full load.
●
End the program [Emission Measurement].
Burner blower switches off.
●
After the burner blower has come to a stop, switch off the
mains plug on the boiler control panel.
GCU compact switches off.
●
Wait 20 seconds before switching the mains switch back
on. Wait for the start phase.
5. Second
automatic calibration
and
measurement of the
flue gas
:
●
On the controller RoCon BF select the program [Emission
Measurement] ->
[Full Load]
but
do not confirm
.
– Make sure that heat can dissipate into the heating network
during emission measurement.
– In the event of burner starting problems, see chap. 7.3.4.
Automatic calibration of the GCU compact and adjust-
ment of the gas valve complete.
Calibration and adjustment are complete two minutes
after the burner symbol
appears on the display.
GCU compact runs at full load.
●
Use the flue gas analyser to check the burner settings and
compare them with tab. 5-1 to tab. 5-4.
a) If the O
2
/CO
2
concentrations lie within the permissible
values:
No further measures are required.
b) If the O
2
/CO
2
concentrations lie outside the permissible
values:
Carry out a 100 % calibration and adjust [Drop Io-base] so
that the setting range is reached (see chap. 7.3.4) and
repeat the measurement.
●
Document the measured values in the "Installation certif-
icate" form and in the operating manual.
WARNING!
A ROTEX GCU compact erected and installed incorrectly may
not operate properly and can be dangerous for the health and
safety of individuals.
●
Only heating technicians, authorised and trained by gas and
energy supply companies are allowed to start up the ROTEX
GCU compact.
CAUTION!
If the ROTEX GCU compact is not started up properly, it could
lead to material or environmental damage.
●
Observe the information concerning water quality in
accordance with chap. 1.2.5.
●
Observe the current technological regulations to prevent
corrosion products and deposits.
●
Measures for desalination, softening or hardness stabili-
sation are necessary, if the filling and top-up water have a
high total hardness >3 mmol/l - total of the calcium and
magnesium concentrations, calculated as calcium
carbonate.
– We recommend the use of Fernox lime scale and corro-
sion protector
KSK
(
15 60 50)
.
●
During operation of the system, the water must be checked
at regular intervals on the building-side manometer (green
range) or by querying the controller (see accompanying
controller manual). If necessary, correct the pressure by
topping up with water.
CAUTION!
The firing unit is programmed to take into account the ageing of
the components. 100 % calibration of the firing unit can still have
a negative impact on this despite compliance with the flue gas
setting values (tab. 5-1 to tab. 5-4).
●
Only calibrate the firing unit when the flue gas setting values
are not adhered to or when a mechanical change has been
made, e.g. by replacing the component with ROTEX original
spare parts.
