– Net flue gas temperature t
– Carbon dioxide content (CO
or oxygen content (O
– CO value
Fig. 40 Recording actual values

6.17.1 Draught
The required draught for the installed flue gas/ventilation
air system must not exceed 100 Pa (1.0 mbar).
DANGER: Risk to life from toxic flue gases
escaping.
B Only operate the boiler with a chimney or
flue system (
6.17.2 CO value
CO values in an air-free state must be below 400 ppm or
0.04 % vol.
Values above 100 ppm indicate an incorrect burner
adjustment, incorrect appliance setup, burner and/or heat
exchanger contamination or burner faults.
B Identify and eliminate the cause.
