SOURCE: I have just purchased three
When I worked Electrical in a Hardware store we were told by Nighthawk and f\First Alert and we told our customers that you want the detectors 4-6 feet off the floor never near a water heater or furnace since this can cause false alarms. The CO will rise, so one on each floor should be enough near a central stair if possible. Other wise make sure at least one is in the bedroom.
