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