okay, poo - hat off too everybody and bowing. cant find the reg that says 200 ppm is ID, give me 24 hours to dig deeper into my memory to where that came from.
best i can do today is point towards gas safe edition six, 10.6.
remember MI beats gas regs.
failure to achieve satisfactory combustion readings.
villa tom hits nail on head,
all though today found out potterton EC two 160 only allow 50ppm CO which was a shock, and they would only class it as AR
annoyed cos i think ime rigt on that number then potterton says ime not its lower, will chase tommorow with more time.
on the plus side i do look beautifull on my video .
