9.10 Measure the flue gases CO emissions

Open at least two thermostatic radiator valves, if present.
Do not switch ON the boiler.
Push on the control panel to open it.
Switch OFF the heating system by pressing the main
switch of the BC10 basic controller (fig. 64, pos. 1).
Remove the cover from the flue gas measuring point
(fig. 65, pos. 1).
Connect the flue gas analyser to the left-hand measuring
point (fig. 65).
Switch ON the heating system by pressing the main
switch of the BC10 basic controller.
Press and hold the "Chimney sweep" button (fig. 64,
pos. 3) (approx. two seconds), until the dot in the right-

appears. See also table 8, "Flue gas test", page 41.
After the LED "Burner operation" (fig. 64, pos. 6) has lit
wait for one minute until the boiler is burning at full load.
Measure the carbon monoxide content at the flue gas
measuring point (fig. 65).
The CO values in air-free condition must be less than
400 ppm or 0.04 vol. %.
Values of 400 ppm or more indicate an incorrect burner
adjustment (see paragraph 9.8, page 52), a dirty gas burner
or heat exchanger or burner faults.
You must determine and remove the cause (see
chapter 12 on page 65).
