CO2 is the most important reading not the ratio? Statement from Valiant literature.
If this is correct then why is this not on the landlords safety certificate for example?
A landlords certificate requires gas rate and gas ratio co/co2 reading.
If these are both correct the boiler is deemed safety checked.
The co2 readings are sometimes lower than 9% in the MI. Am I contravening any gas regulations by not correcting it?
For example 7per cent instead of 9 percent in MI. I rang vaillant and they said its 'my call'.
