1.
Press until the service display has counted up to
"100" (= 100 %).
2.
Check the CO
2
content at the flue pipe.
For permissible CO
2
content, see above table.
3.
Check control cables:
■
Connection and kink-free routing
■
Application and seating of retaining clips
Note
The unconnected end of the hose is open in open
flue operation. For
room sealed
