What locations should I avoid when installing the CO alarm?

Do not install the alarm in closed spaces (kitchen cabinets, behind curtains), obstructed areas (behind furniture), on floors, near doors/windows, behind fans or air vents, in areas with temperatures below -10°C or above 45°C (unless necessary), in dusty or damp locations, near kitchen appliances, or where it can be easily blocked. Avoid areas with excessive soot and dust that could clog the sensor.
