Where Should You Mount A Carbon Monoxide Detector. 15cm from the ceiling. But if not correctly placed carbon monoxide detectors wont be effective.

However this is not always possible. Mount detectors on the wall at least a couple of feet below your ceiling or even lower. Thus I recommend that you install as many CO detectors as needed to be safe in your home.
Any fuel burning appliance vehicle tool or other device has the potential to produce dangerous levels of CO gas.
If you are getting a single carbon monoxide detector place it near the sleeping area and make certain the alarm is loud. Homeowners should remember not to install carbon monoxide detectors directly above or beside fuel-burning appliances as appliances may emit a small amount of carbon monoxide upon start-up. Just as important as where to place your CO detector is where not to place it. WHY IT MATTERS WHERE YOU INSTALL CO DETECTORS.
