1. Information About Carbon Monoxide

Conditions That Can Produce Carbon Monoxide

The following conditions can result in transient CO situations: 

• Excessive spillage or reverse venting of fuel-burning appliances 

caused by outdoor ambient conditions, such as, wind direction and/

or velocity, including high gusts of wind, heavy air in the vent pipes 

(cold/humid air with extended periods between cycles).

• Negative pressure resulting from the use of exhaust fans.

• Simultaneous operation of several fuel-burning appliances competing 

for limited internal air.

• Vent pipe connections vibrating loose from clothes dryers, furnaces, or 

water heaters.

• Obstructions in, or unconventional, vent pipe designs which can 

amplify the above situations.

• Extended operation of unvented fuel-burning devices (range, oven, 

fireplace, etc.).

• Temperature inversions which can trap exhaust gases near the 

ground.

• Vehicle idling in an open or closed garage, or near a home.

To be safe, know the possible sources of CO in your home. Keep fuel-

burning appliances and their chimneys and vents in good working 

condition. Learn the early symptoms of exposure, and if you suspect 

CO poisoning, move outside to fresh air and get emergency help. Your 

first line of defense is an annual inspection and regular maintenance of 

your appliances. Contact a licensed contractor or call your local utility 

company for assistance. 

Information About Carbon Monoxide Alarms –  

What They Can and Cannot Do:

CO alarms provide early warning of the presence of CO, usually before a 

healthy adult would experience symptoms. This early warning is possible, 

however, only if your CO alarm is located, installed and maintained as 

described in this guide.
Because carbon monoxide is a cumulative poison, long-term exposures to 

low levels may cause symptoms, as well as short-term exposures to high 

levels. This Kidde unit has a time-weighted alarm – the higher the level of CO 

present, the sooner the alarm will be triggered.
