Gas conversion
Applicability:
Except Belgium
1.
Observe the applicable national regulations.

To convert the gas, use only Vaillant conversion sets or
Vaillant spare parts.
3.
Follow the instructions contained in the documentation
that is supplied with the conversion sets or spare parts.
6.4
Checking that the flue gas sensor works
correctly
If the flue system is fully or partially blocked or the local air
pressure conditions restrict the smooth flue system, the flue
gas sensor registers an increase in temperature and inter-
rupts the gas supply.
Check that the flue gas sensor is working correctly, as de-
scribed below.
