I had a flue gas reading carried out by a local GasSafe engineer following a service, and so he disconnected it, telling me that it should be considered dangerous as the CO/CO2 ratio from his Flue Gas Analyser was 0.0405. I called out the manufacturers' engineer to see what was faulty, and he reported that the ratio was in fact only 0.0010 and within limits.
Now I'm piggy-in-the-middle, not knowing what to believe. The printout from the local engineer looks a little odd to me, as the readings include:
02% 20.6
CO2% -0>-
CO ppm 81
CO/CO2 0.405
The CO is only a little more than last year's test, but what does "-0>-" mean for the CO2%? Is this a blip which has caused the ratio to be wrong?
The meter ID (?) at the top is K450 1.0, but I'm not sure if that indicates who the meter maker is?
Thanks, Alec.
