I hope this is a straight forward question for someone to answer. Is CO heavier or lighter than air and depending on the answer is it likely to accumulate in areas above or below the scource of combustion (eg a gas boiler)?

Carbon monoxide is lighter than air (1.250 kg per cu.m. compared to air 1.275, at Standard temp and pressure

the difference is minor and the slightest of air currents (e.g. the heat from the boiler) will mix it with the air so you are very unlikely to get a specific area of accumulation

Whoops - didn't read the whole questio!!

Agree with the comment above... the density difference is slight and if there is any substantial airflow, there will be mixing.
