A friends glow worm 24cxi has recently been serviced and have noticed a slight difference after the service and wanted to check to ensure that it is not something significant.
The Combustion Analyser Test Point on the Flue use to have a glowing pale blue colour emanating from it and after the service is now colourless. Is this something to be concerned about?
Thanks
