7.12.1 CO
2
content, natural gas type A (minimum output)
If CO
2
content is below 9,0 % or above 9,5 %.
▶ Use the low-output adjusting screw to adjust the level to 9,1 % CO
2
.
– Turning the screw clockwise increases the CO
2
level.
– Turning the screw counter-clockwise reduces the CO
2
level.
7.12.2 Reading off and comparing CO
2
levels
▶ After reading off the CO
2
level or adjusting it on the Monitor readings/
Burner menu, read off the flame ionization current and compare with
the specified levels.

7.13 Checking and monitoring CO
2
level at maximum
output
▶ Press the button to increase the boiler output to a higher
percentage.
▶ Read off output on the RC35 or by means of the service keys.
▶ Wait until at least 70 % of the load is reached.
▶ Check CO
2
content again.
▶ Read off flame ionization current (and compare with the specified
levels).
7.14 Recording measured values
▶ Take the following readings at a test point on the vent pipe and record
them in the commissioning report (

Section 7.20, page 39):
– Pressure differential
– Flue gas temperature t
A
– CO
2 level or oxygen content
(O
2
) (Carbon Dioxide)
– CO content (Carbon Monoxide)

7.14.1 Switching the status display on the BC10 to show the boiler
temperature
▶ Press the button to change the display to the next status.
The current operating pressure is displayed.
▶ Press the button to change the display to the next status.
The operating status (display code) is displayed.
▶ Press the button to change the display to the next status.
The boiler temperature is displayed.
7.14.2 Returning to operating mode from the flue gas test
▶ Press the button to cancel the flue gas test.
▶ Switch the RC35 back to the operating mode.
▶ Close the flap on the RC35.
▶ If the boiler is intended for operation with the Logamatic 4000
control system, remove the RC35 again.
▶ Switch on the Logamatic 4000 control system.
7.14.3 Pressure differential
The required pressure differential for the flue gas/air supply system
installed must not be greater than 0.4 inches W.C.
▶ If the pressure differential at maximum output is higher than 0.4
inches W.C., contact the flue system planner responsible and check
the calculations and design of the flue gas/air supply system.
7.14.4 CO content
The CO content in an air-free state must be below 400 ppm or 0.04% by
vol.
Levels above 100 ppm indicate incorrect burner adjustment, incorrect
appliance settings, dirt in the burner or heat exchanger or burner faults.
▶ Identify and eliminate the fault.

DANGER: Risk of fatal injury due to poisoning by
escaping flue gas!
▶ Only operate the boiler in conjunction with a
connected and approved venting system.
