Carbon monoxide is slightly less dense than air.

Install as directed by the manufacturer.

If carbon monoxide is LESS dense than air (and it is), it would rise, not sink to the floor so a detector should be mounted higher. That said, the difference in density is only slight so it mixes with air and so is present at all levels.
