3-4 Checking the CO2
①
The combustion may be checked after running the boiler for several minutes.
To do this it is necessary to set the boiler to Calibration Mode.
②
Ensure that all external controls are calling for heating with maximum output.
③
The appliance should be check visually for obvious defects.
④
There are two test points in the flue, one for flue gas and the other for air.
⑤
Open the air and flue gas test points.
⑥
Insert the flue gas analyzer probe as far as the retainer.
⑦
Allow the boiler to reach thermal equilibrium (around 5~10min)
⑧
The CO and CO2 values should be check each below 200ppm and 5%.

NOTE
: To ensure correct readings the boiler must have reached maximum operating temperature.
. Testing the boiler before thermal equilibrium has been attained will give incorrect readings.
NOTE :
If you have only 1 probe, measure separately air and flue gas, close the test point not in
use.
