6.
Start up the product with the check programme
P.01
.
▽
If
S.85
is shown, the hot water circulation must be
extended.
◁
S.93
is briefly displayed.
◁
If the display switches to
S.04
, the product is ready
for the measurement.
7.
Measure the gas flow pressure in comparison with the
atmospheric pressure.
–
Permissible gas flow pressure for operation
with G20 natural gas: 1.8 … 2.5 kPa (18.0
… 25.0 mbar)
–
Permissible gas flow pressure for operation
with G25 natural gas: 1.8 … 2.5 kPa (18.0
… 25.0 mbar)
–
Permissible gas flow pressure for operation
with G31 liquid gas: 4.25 … 5.75 kPa (42.50
… 57.50 mbar)
8.
Decommission the product.
9.
Close the gas isolator cock.
10. Remove the pressure gauge.
11. Tighten the screw on the measuring nipple
(1)
.
12. Open the gas isolator cock.
13. Check the measuring nipple for gas tightness.
Conditions
: Gas flow pressure
not
in the permissible range
Caution.
Risk of material damage and operating
faults caused by incorrect gas flow pres-
sure.
If the gas flow pressure lies outside the per-
missible range, this can cause operating
faults in and damage to the product.
▶
Do not make any adjustments to the
product.
▶
Do not start up the product.
▶
If you are unable to remedy the fault, contact the gas
supply company.
▶
Close the gas isolator cock.
7.12.2 Checking the CO
₂
content
Caution.
Risk of operating faults caused by the
corruption of the measured values during
the calibration.
Operating the product with the front casing
open or not completely installed, or with the
flue pipe open, may negatively influence the
calibration of the gas-air mixture.
▶
During the calibration and when measur-
ing the CO
₂
content, you must operate the
product with the front casing installed and
closed, and with the flue pipe completely
installed.
1.
Start up the product.
Note
Since the combustion can be continuously
monitored by the product, you do not need to
check the combustion.
2.
Press
and
at the same time to activate the max-
imum output operation.
▽
If
S.85
is displayed in the
Live Monitor
, the circula-
tion must be increased in the heating system.
◁
The display shows
Chimney sweep
and
S.93
at the
same time.
◁
The product runs through a calibration process on
the flue gas installation and the gas quality.
3.
Wait until the calibration process has taken place.
◁
After the calibration procedure ends, the display
shows
Chimney sweep
and
S.04
at the same time.
4.
Now measure the CO
₂
content at the flue gas analysis
point.
◁
The product restarts the measuring programme after
the burner has been operating for five minutes so
that it can take heating effects into consideration.
◁
The combustion automatically optimises itself. CO
₂
content of 8.0 to 10.5 vol.% (natural gas) and of 9.0
to 11.8 vol.% (liquid gas) can be measured.
Note
After initial start-up or starting the check pro-
gramme
P.04
, depending on the heating par-
tial load that is set and the existing heat con-
sumption by the heating installation, it may
be the case that the product runs through the
measuring programme several times. During
the calibration process, no flue gas analysis
is possible.
7.13
Checking leak-tightness
▶
Check the gas pipe, the heating circuit and the hot water
circuit for leak-tightness.
▶
Check that the air/flue pipe has been installed correctly.
Conditions
: Room-sealed operation
▶
Check whether the vacuum chamber has been closed
tightly.
7.13.1 Checking the heating mode
1.
Make sure that there is a heat requirement.
2.
Call up
Live monitor
.
◁
If the product is working correctly, the display shows
S.04
.
7.13.2 Checking the hot water generation
1.
Ensure that the cylinder charging mode is requesting
heat.
2.
Call up
Live monitor
.
◁
If the cylinder is charged correctly, the display
shows
S.24
.
Conditions
: Controller connected
▶
Set the hot water temperature on the boiler to the max-
imum possible temperature.
