Start-up procedure
9.8
Carry out a leakage test in operating conditions
WARNING:
Leaks may be caused to pipes and screw connections
during commissioning and maintenance activities.
▶ Carry out a proper leak test.
▶ Only use approved leak detection agents for leak
detection.
▶ Press and hold the "Chimney sweep"
(approx. 2 seconds), until the dot in the right-hand bottom corner of
the display ( fig. 65, [9]) appears ( table 12, page 31).
▶ After the LED "Burner operation" ( fig. 65, [6]) has lit up wait for
1 minute until the boiler is burning at full load.
▶ Use a foaming product to check all sealing locations in the total gas
circuit of the burner while the burner is active.
d
▶ Press the "Chimney sweep"
reading ( table 12, page 31).
9.9
Check and adjust the flue gases CO
CAUTION:
Take adequate time to properly measure the CO
▶ Changes will only be measurable after about
1 minute.
▶ Let the CO
value stabilize for about 30 seconds
2
before reading and/or readjusting.
▶ Open at least 2 radiator valves, if present. Do not switch ON the
boiler.
▶ Push on the control panel to open it.
▶ Switch OFF the appliance by pressing the main switch of the BC10
basic controller ( fig. 65, [1]).
▶ Remove the cover from the flue gas measuring point ( fig. 66, [1]).
▶ Connect the flue gas analyzer to the left-hand measuring point, insert
it roughly 2" ( fig. 66).

▶ Press and hold the d button ( fig. 69, [3]) (approx. 2 seconds),
until the dot in the right-hand bottom corner of the display
( fig. 69, [9]) appears ( table 12, page 31).
▶ After the "LED Burner operation" ( fig. 69, [6]) has lit wait for
1 minute until the boiler is burning at full load.
▶ Measure in the flue gas measuring port, with closed boiler door, the
CO
percentage. The value has to be 9.3% ± 0.2%.
2
▶ If necessary: open the boiler door and adjust the CO
9.3% by means of the adjustment screw on the gas valve with the red
sleeve ( fig. 67) and close boiler door again. Note the set value in
table 27 on page 56.
If the CO
percentage is not adjustable above 9% the problem can be:
2
• The gas pressure is to low ( § 9.7, page 36).
• CO
analyzer set incorrectly. Set CO
2
• Very low calorific gas. No solution, accept lower CO

NOTICE
▶ The adjustment screw has no limit stop, there for it is
not defined, in advance, that turning left or right will
give a higher or lower value.
▶ Simultaneously press and hold the
2 seconds, to activate service mode for partial load setting.
c
▶ Press and hold the
button until the display shows:
– [l/3/6| with a 80 kW boiler or
– [l/3/0| with a 100 kW boiler.
▶ After the load is adjusted to partial load, wait for 1 minute until the
boiler burns at partial load.
▶ Measure in the flue gas measuring port the CO
value has to be 1 to 1.5% lower than the measured value at full load.
E.g. full load measured value = 9.3:
9.3 - 1 = 8.3 and 9.3 - 1.5 = 7.8
So when the CO
percentage at full load is 9.3%, the partial load CO
2
percentage value has to be between 8.3% and 7.8%.
If necessary:
▶ Adjust the CO
percentage to the calculated value, by means of the
2
air/gas ratio adjustment screw [1]. The adjustment screw is located
behind the screw plug.
▶ Open the screw plug.
▶ Turn adjustment screw to the left for a lower CO
