Don't install your CO detector in areas with high heat and/or humidity, or in direct sunlight – think bathrooms, sunrooms, small laundry rooms.
If your furnace is located in the basement, be sure to place a CO detector there, as well. Likewise, if you have a gas clothes dryer, put an alarm in the laundry room. Place one in the garage, if you park your cars there.
A carbon monoxide detector should not be placed within fifteen feet of heating or cooking appliances or in or near very humid areas such as bathrooms. For more information about carbon monoxide safety, visit the National Fire Protection Association.
Heat detectors should be placed at locations where smoke detectors are not suitable. These include kitchen, attic, garage, laundry rooms, furnace rooms, etc.

The Consumer Product Safety Commission recommends a detector on each floor of a residence. At a minimum, a single detector should be placed on each sleeping floor with an additional detector in the area of any major gas burning appliances such as a furnace or water heater.
The physical properties of carbon monoxide (CO) and the detectors themselves make positioning critical for your protection. CO is lighter than air and as it rises, it accumulates near ceilings. Detectors need to be placed higher on the walls or on the ceiling, but not so high that they're easy to ignore.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
Carbon monoxide alarms should be positioned at head height, either on a wall or shelf, approximately 1-3 metres away from a potential source of carbon monoxide. Individual manufacturer's instructions should be followed for both smoke and carbon monoxide alarms.
The International Association of Fire Chiefs recommends a carbon monoxide detector on every floor of your home, including the basement. A detector should be located within 10 feet of each bedroom door and there should be one near or over any attached garage. Each detector should be replaced every five to six years.
CO2 levels rise and fall regularly indoors. There are many factors that affect CO2 levels including ventilation, amount of people, and length of time in an enclosed space.
Carbon Monoxide sources in the home
Water heaters. Furnaces or boilers. Fireplaces, both gas and wood burning. Gas stoves and ovens.
A carbon monoxide detector should not be placed within three meters of heating or cooking appliances or in or near very humid areas such as bathrooms. For more information about carbon monoxide safety, visit the National Fire Protection Association.
Appliance malfunction – there are a number of home appliances that use combustion to operate, including clothes dryers, hot water heaters and stoves. Should any of these appliances be poorly vented or have a problem where CO is escaping, your CO alarm will trigger.

The U.S. Consumer Product Safety Commission (CPSC) recommends that every home should have a carbon monoxide (CO) alarm.
What Does an Emergency Alarm Chirp Mean? This meaning is probably the most self-explanatory. When your carbon monoxide detector chirps 4 times in a row and pauses, this means it has detected unsafe levels of carbon monoxide. This means your entire household should evacuate immediately and seek fresh air.
The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances – like stoves and hot water heaters. Poorly ventilated fireplaces and other gas- or wood-burning appliances can also pose danger.
