The Dangers of Carbon Monoxide
Carbon Monoxide (CO) is a toxic gas. It cannot be seen, felt, tasted, or smelled. The
effects of CO poisoning can cause household members to become extremely ill or
even cause death. Due to damage, poor maintenance, or defects, many
appliances like furnaces, ovens, fireplaces, kerosene heaters, and grills may silently
emit CO. Advance warning of CO poisoning is only possible if you install and maintain a CO detection device.
The amount of CO in the air is measured in parts per million (ppm). Carbon
monoxide occurs when fuel burns without sufficient oxygen (incomplete
combustion). This type of malfunction can happen to any fuel-burning appliance at
any time. Many fireplace chimneys, for example, can become filled with leaves during
the fall season. If enough leaves, dirt, and soot are accumulated in the chimney,
proper ventilation will be interrupted. This can cause a backdraft of CO into the
home. The result can be fatal. With proper maintenance and cleaning, however, the
potential for CO build up can be reduced.
Carbon monoxide poisoning is a serious issue. Many families suffer daily, and over
one thousand lives are lost each year because of this deadly household gas. With
proper maintenance and care, this CO alarm can give family members advance
warning to CO emissions. Please read this manual thoroughly to learn how to properly install, operate, clean, and repair your CO alarm, and for important safety tips to
safeguard your family from deadly CO poisoning.

CO Alarm Features cont.
! WARNING
This CO alarm is designed to detect carbon monoxide gas from any
source of combustion. It is NOT designed to detect smoke, fire, or any
!
other type of gas. If this CO alarm sounds its alarm horn, DO NOT
! alarm horn requires your immediate
assume that it is a false alarm. The
action.
! WARNING
This product is intended for use in ordinary indoor locations of family living
units. It is not designed to measure compliance with Occupational Safety
!
and Health Administration (OSHA) commercial or industrial standards.
!
Where to Install Your CO Alarm
! WARNING
Carbon monoxide gas can be anywhere and everywhere. CO gas is equal
to or slightly lighter than air, and disperses evenly with the air in a room.
!
Therefore, install this CO alarm where air circulation is best. DO NOT
mount the CO alarm within 1 foot of the ceiling/wall or wall/wall intersection, or other dead air spaces.
Since most CO fatalities occur while families are sleeping, we recommend that you install
at least one CO alarm in the hallway outside each separate sleeping area and one inside
each bedroom or sleeping area.
!
We also recommend that you install a CO alarm on every separate living level of the home
where household members frequently spend
! time, as well as in the basement.
See figures 1, 2, and 3 for typical CO alarm locations within the home.
! CAUTION
This alarm will only indicate the presence of carbon monoxide gas at the sensor.
Carbon monoxide gas may be present in other areas.

Symptoms of Carbon Monoxide Poisoning
Carbon monoxide poisoning has many symptoms. However, some symptoms are
very similar to flu symptoms, the effects of intoxication, or drug usage. In many CO
cases, people feel ill and stay home to rest. This only compounds the CO poisoning
because they stay in the home where CO is present.
As CO levels rise, the symptoms become more extreme. At low levels people will suffer headaches and mild nausea. At higher levels unconsciousness, heart failure, and
even death can occur.
The following symptoms are related to CARBON MONOXIDE POISONING and
should be discussed with ALL members of the household:
Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as flu
symptoms).
Medium Exposure: Severe throbbing headache, drowsiness, confusion,
fast heart rate.
Extreme Exposure: Unconsciousness, convulsions, cardio-respiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims
are aware they are not well, they become so disoriented they are unable to save
themselves by either exiting the building or calling for assistance. Also, young children, the
elderly, and household pets may be the first affected by CO poisoning.
The important factor with any CO poisoning, however, is time. At high levels, CO can
cause death in just minutes. At lower levels, it could take from hours to days of constant CO exposure to have the same life-threatening effect.
The chart below illustrates the symptoms of CO poisoning by concentration of CO
and its effect over time.
Slight headache within 2-3 hours.
Frontal headache within 1-2 hours.
Dizziness, nausea, and convulsions within 45 minutes.
Insensible within 2 hours.
Headache,dizziness and nausea within 20 minutes.
Death within 2 hours.
Headache,dizziness and nausea within 5-10 minutes.
Death within 30 minutes.
Headache,dizziness 1-2 minutes.
Death in less than 15 minutes.
Death in less than 3 minutes.

Conditions That Can Cause CO Levels To Change
The following conditions can result in transient CO situations in the home.
1. Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as:
a. Wind direction and/or velocity, including high gusts of wind. Heavy air in the
vent pipes (cold/humid air) with extended periods between cycles.
b. Negative pressure differential resulting from the use of exhaust fans.
c. Simultaneous operation of several fuel burning appliances competing for limited
internal air.
d. Vent pipe connections vibrating loose from clothes dryer, furnaces, or water
heaters.
e. Obstruction in or unconventional vent pipe designs which can amplify the
above situations.
2. Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.)
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage, or near a home.

Home Safety Tips
Many CO poisonings are caused by equipment failures due to poor maintenance,
product defects, and damaged parts. The following is a list of safety tips to help prevent CO poisoning within your home:
1. Have all fuel-burning appliances inspected and cleaned yearly by a qualified
service technician. The furnace, water heater, and stove are some of the leading
sources of CO in homes.
2. Clean fireplace vents and chimney regularly. A blocked chimney could cause a
backdraft of CO into the home. Do not cap chimney. This will cause a backdraft of
CO into the home.
3. Do not cap or cover a drafthood or exhaust vent to any appliance. This will trap
dangerous CO inside the house.
4. Do not close off or confine your fuel-burning appliances in a closed area. They
need plenty of ventilation to operate properly.
5. Do not use liquid propane (LP) or charcoal grills indoors.
6. Do not operate any gasoline-powered equipment indoors.
7. Allow for plenty of ventilation when using a kerosene heater. Do not use in small
areas.
Preventive maintenance, common sense, and a CO detection device are some of the
best solutions to preventing CO poisoning. However, a dangerous situation can happen to anyone at any time.
The following list illustrates some danger signs of CO presence.
1. Soot and dirt build-up seeping out of chimney or other exhaust vents.
2. A mostly yellow, rather than clear blue, burner flame or pilot flame in gas
appliances.
3. A draft of air coming from appliances, chimneys, or vents.
IF YOU HAVE FLU-LIKE SYMPTOMS OR SUSPECT CO POISONING,
SEEK MEDICAL ASSISTANCE IMMEDIATELY.
