Appendix B - CO Detector Installation Overview
B-1. Selecting Installation Location
Selecting a suitable location is critical for the CO detector. The Consumer Product Safety Commission (CPSC) recommends to use at
least one CO detector per household, located near as possible to sleeping areas of the home, because the human body is most
vulnerable to the CO gas effect during sleeping hours.
For added protection, install additional CO detectors in every separate bedroom and on every level of your home. If your bedroom
hallway is longer than 14 meters (40 feet), install a CO detector at BOTH ends of the hallway. Install an additional detector 6 meters (20
feet) away from the furnace or fuel burning heat source.
