10 Maintenance
10.1 General
The boiler requires little maintenance if it is correctly set. The boiler
only requires an annual check and cleaning if necessary.
10.2 Inspection
The annual inspection of the boiler can be restricted to the following
operations:
- Measure the combustion and check the operation
- Clean the siphon
- Checking condensates discharge
- Checking the ignition electrode and the ionization sensor
- Set the gap between the ignition electrodes: 3 to 4 mm
10.2.1 Checking the combustion in the boiler
This check can be carried out by measuring the CO
the combusted gas at the measurement point.

Correct the burner setting to ±0.3% CO
The temperature of the combusted gases can also be measured at the
measurement point in the evacuation pipe. The temperature of the
combusted gas must not exceed the temperature of the return water by
more than 30 °C. If it turns out that boiler combustion has not been
optimised after this check, clean the installation.

- Check the general condition of the flue
- Checking the hydraulic pressure
(minimum 0.3 bar for Gas 110 Eco 65,
minimum 0.5 bar for Gas 110 Eco 115).
Add water to the installation if necessary (Recommended pressure:
1.5 mbar)
- Check the ionization current: 4 to 9 µA.
