Does anyone know the correct setting for the air damper on the Riello
40 G7X burner of a Myson Velaire Vitesse 60/80 burning 28 second oil?
An 'engineer' - who fiddled about then admitted he did not really know
what the fault was - moved the aperture and it has never worked
properly since. I want to check the aperture is correct before I check
the electrode settings in the combustion head.
The boiler often fails to fire up automatically, but starts after the
reset button has been pressed a couple of times. The fault finding
chart in the manual suggests the electrodes may be sooted up but also
makes it clear that the air damper setting is critical to clean
Thanks in advance.
