EMISSIONS

B Open at least 2 thermostatic radiator valves. Do not
switch on the boiler.
B Push on the control panel to open it (
page 40).

B Switch on the heating system by pressing the mains
switch of the BC10 basic controller (
B Press and hold the "Chimney sweep" button
( fig. 90, [3]) (approx. 2 seconds), until the dot in
the right-hand bottom corner of the display
( fig. 90, [9]) appears. See also table 10, "Flue gas
test", page 42.
B After the "Burner" LED (
for one minute until the boiler is burning at full load.
B Measure the carbon monoxide content at the flue gas
measuring point ( fig. 91).
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
( section 10.2.7, page 52), a dirty gas burner or heat
exchanger or burner faults.
B You must determine and remove the cause
( chapter 12, page 61).
B Press the "Chimney sweep" button (
clear the reading. See also table 10, "Flue gas test",
page 42.

10.2.10 CARRYING OUT A FUNCTION TEST

B During initial start-up and annual inspection and/or
needs-oriented servicing, make sure that all control,
regulating and safety devices are in full working order
and, if applicable, check them for correct adjustment.
B The gas and water circuits must be tested for leaks
( sections 10.2.1 and 10.2.8).

10.2.11 MEASURING THE IONISATION CURRENT

B Push on the control panel to open it (
page 40).
B Open at least 2 thermostatic radiator valves. Do not
switch on the boiler.
B Switch off the heating system by pressing the mains
switch of the BC10 basic controller
B Turn the vent key through a quarter rotation to undo
the boiler door lock (
page 47).
B Push the fastener down and open the boiler door
( fig. 71, page 47).
