The scope of inspection includes:
Opening the combustion chamber.
If there is damage around the combustion chamger, the
burner must be removed (see chapter 7.4).
Clean the burner surface (cloth, plastic brush).
Conduct a visual inspection of the ignition and ionisation
electrodes for damage and correct electrode gap
(see chapter 7.3.7 "Setting ignition and Ionisation
electrodes").
In the course of maintenance work, the safety relevant
components must be additionally inspected for the
expiration of their nominal service life:
– Automatic firing CM124-R1: 10 years or 250.000
burner starts,
– Safety gas control block 10 years or 250.000 burner
starts,
– Overpressure safety valve: 10 years.
If necessary, replace faulty parts.
Replace the combustion chamber inserts if they were
removed for cleaning of the combustion chamber.
Close the combustion chamber.
Check the gas line for leakage.
Put the burner into operation and let it run for about 5 minutes
in Emission Measurement operating mode.
Check combustion values:
– Flue gas temperature at measuring sockets of the flue gas
pipe. (Target value < 90 °C),
– O - or CO -content (see chapter 7.3.1 "Settings"),
2 2
– CO content (target value < 50 ppm).
If the combustion values do not fall within the target range,
the burner must be adjusted accordingly (see chapter 7.3)
We recommend, to enter all measured values and the
conducted work with the date and signature into the
enclosed operating handbook.
