Found this info from Kiddie:
"There is no specific height for carbon monoxide. CO weights almost the same as air so it spreads pretty evenly. As well, CO alarms measure for the overall exposure to CO, not just its presence. They simulate the absorption rate into the human body because low levels of CO over a long period of time is as dangerous as high levels in a matter minutes. If you are unsure about the potential for CO, consider gettting a digital display alarm that lets you know of low levels of CO, well before it gets dangerous."
On the other hand, the CO alarm instructions for the one I have at home said to place it 3' from the floor.
