hi, I am after some advice, I recently fitted a new gas valve to a vaillant ecotec earlier. the boiler was fitted in 2015 and has been serviced since
anyway I put my analyser in the combustion side of the flue and the readings were extremely high, something along the lines of
CO ppm —OR—
Ratio 0.2555
CO2 10.0 (lpg co2 perfect)
I thought the gas valve was faulty, so fitted another and still get the same problem, why am I getting ridiculous parts per million when it should be no more than 250? It’s that high my Kane anyliser doesn’t give a number.
I inpected the main burner and all appeared normal, I also cleaned it and then fitted a new vaillant graphite seal. I also inspected the flue and it was all perfect.
still I was getting these ridiculous readings so I put the analyser into the other side of the flue to get an O2 reading which was correct at 20.9 and there was 0 ppm.
can anybody point me in the right direction as to what the problem is as I have never had readings as high as this before. I often have to adjust them but they are always only slightly out.
