of the boiler is correct. If NOT, adjust the CO
2
setting according
to the instructions in the chapter below.
12

sampling point back in its place. Make sure it is gastight.
13
Put the front panel back in its place.

To adjust the carbon dioxide setting
INFORMATION
Only adjust the CO
2
setting when you have checked it first
and are sure adjustment is necessary. In Belgium, any
modifications to the gas valve MUST be performed by a
