Thanks for your help, I'm gonna get that book it looks like it explains better than the Viper one at least!

If you only doing first fix you shouldn't be worried too much about numbers.

For flueless heater the CO² should be no more than 2800ppm where personnel are likely to be working. (unless it's changed) over the last 5years.

I've got no card so far, would this number be on my ACS certificate?

hell boy mine was on my acop certificate

Cheers, I've read that bit in the commercial viper book but was wondering how this is tested in practice. Would I use a flue gas analyser to measure the POC and check the CO2 level, or just ensure there is adequate ventilation following manufacturer's instructions?

I am mainly going to be servicing flueless radiant tube, warm air and spot heaters but obviously I want to be sure the ventilation is adequate for them before I sign them off as being safe.
