7.11.5 Checking the CO
₂
content and, if
necessary, adjusting it (air index setting)
1.
Start up the product with the check programme
P.01
.
2.
Wait at least five minutes until the product reaches its
operating temperature.
3.
Measure the CO
₂
and CO/CO
₂
content at the flue gas
analysis point.
4.
Compare the measured value with the corresponding
value in the table.

▶
For natural gas only: Only perform the adjustment
in small increments of a 1/8 turn and wait approx.
one minute after each adjustment until the value
stabilises.
▶
For liquid gas only: Only perform the adjustment in ex-
tremely small increments (approx. 1/16 turn), and wait
approx. one minute after each adjustment until the value
stabilises.
▶
After you have implemented the settings, press
(
).
▶
If an adjustment is not possible in the specified adjust-
ment range, you must not start up the product.
▶
If this is the case, inform Customer Service.
▶
Refit the covering cap.
▶
Install the front casing.

Checking leak-tightness
▶
Check the gas pipe, the heating circuit and the domestic
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.
7.12.1 Checking the heating mode
1.
Make sure that there is a heat requirement.
2.
Call up

Thoroughly flushing the heating installation
("hot")
1.
Operate the appliance until the boiler and the heating
system are up to temperature.
2.
Check the heating system for leaks.
3.
Connect a hose to the drain valve located at the lowest
position of the heating system.
4.
Shut off the boiler, open the drain valve and all purge
valves on the radiators and allow the water to flow out
of the heating system and the boiler quickly and fully.
5.
Close the drain valve.
6.
Fill the heating system again with water as described in
Filling the heating installation (
→
Page 19) and Purging
the heating installation (
→
Page 20).
7.
Re-fill the system until the system design pressure of
0,1 MPa (1,0 bar) is attained.
