z Open at least two thermostatic radiator valves, if present.
Do not switch ON the boiler.
z Push on the control panel to open it.
z Switch OFF the heating system by pressing the main
switch of the BC10 basic controller (fig. 64, pos. 1).
z Remove the cover from the flue gas measuring point
(fig. 65, pos. 1).
z Connect the flue gas analyser to the left-hand measuring
point (fig. 65).
z Switch ON the heating system by pressing the main
switch of the BC10 basic controller.
z Press and hold the "Chimney sweep" button (fig. 64,
pos. 3) (approx. two seconds), until the dot in the right-
hand bottom corner of the display (fig. 64, pos. 9)
appears. See also table 8, "Flue gas test", page 41.
z After the LED "Burner operation" (fig. 64, pos. 6) has lit
wait for one minute until the boiler is burning at full load.
z 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.
z You must determine and remove the cause (see
chapter 12 on page 65).
