7 Checking and maintenance

7.1 General
The boilers will undergo an inspection at least once a year or every
3000 hours of operation.

7.2 Checks

The annual inspection of the C 230 ECO includes the following
operations:

- Checking the combustion in the boiler

- Setting the ignition electrode

7.2.1 Checking the combustion in the boiler
This check can be carried out by measuring the CO
the combusted gas discharge duct at the measurement point and the
gas pressure in the combined valve unit. To do this, heat the boiler to
a water temperature of around 70°C.
7.2.2 Setting the ignition electrode
Check the setting of the ignition electrode. The gap in the ignition
electrode must be 3-4 mm. Otherwise, replace the electrode (and the
gasket). Check the good general appearance (particularly that there
are no shards, cracks, fouling on the porcelain) and the state of wear
of the electrodes.

- Checking tightness (hydraulics, combusted gas discharge and
gas)
- Checking the hydraulic pressure
/ O content in The temperature of the combusted gases can then be measured at
2 2
the measurement point in the combusted gas discharge duct. This
temperature may not exceed the flow temperature by more than
30°C.
If the combustion gas is more than 30°C higher than the flow
temperature setting, the heating body must be cleaned.
