Checking the expansion vessel

1. Remove the cover from the sealed chamber.
¼ see chapter: "Removing the cover from the sealed
chamber", page 57
2. Check the expansion vessel and replace it if necessary.
8.2.3.

Checking the ionization current

Check the ionization current at full load and low load. The value is
stable after 1 minute. If the value lies below 3 µA, replace the ignition
electrode.
¼See chapter: "Reading out measured values", page 65.
8.2.4. Checking the tightness of the flue gas
evacuation and air inlet connections
Check the tightness of the flue gases evacuation and air inlet
connections.
8.2.5.

Checking combustion

The check on combustion is done by measuring the percentage of
O in the flue gas discharge flue. To do this, proceed as follows:
2
1. Unscrew the plug of the flue gas measurement point.
2. Insert the probe for the flue gas analyser into the measurement
opening.
WARNING
Ensure that the opening around the sensor is completely
sealed when taking measurements.
CAUTION
The flue gas analyser must have a minimum accuracy of
0,25 % O .

3. Set the boiler to full load.
¼ see chapter: "Checking/setting values O
61
The boiler is now operating at full load. Measure the percentage
of O and compare this value with the checking values given.
2
4. Set the boiler to part load
¼ see chapter: "Checking/setting values O
62
The boiler is now operating on part load. Measure the percentage
of O and compare this value with the checking values given.
