Additional Safety Tips  
Have your fuel-burning equipment checked periodically for  
safety and efficiency by a qualified service technician.  
Warning: This carbon monoxide alarm is designed to  
detect carbon monoxide gas from ANY source of  
combustion. It is Not designed to detect smoke, fire or  
any other gases. This device is not suitable for  
installation in a hazardous location, as defined in the  
Canadian Electrical Code.  
• After 4 minutes it will flash quickly 4 times  
(synchronized with the horn), repeating every  
minute.  
If you are adding a wood or coal burning stove to a home,  
make sure that the stove is properly installed and vented.  
Check with the Building and Inspections Department of  
your local municipality or consult a heating contractor  
before installation. If you have already installed a wood or  
coal stove without a building permit or inspection, consult  
your local municipal building authority. Some “do-it-your-  
selfers” have unknowingly created dangerous conditions.  
Once you file for a permit, a qualified inspector will check  
your installation and explain how to rectify any mistakes.  
Do not expose yourself to carbon monoxide through  
carelessness. Never operate a gasoline-powered engine in a  
confined or enclosed space such as a garage or tool shed.  
Never use a kerosene stove or charcoal grill in a confined  
space such as a closed garage or recreational van.  
On masonry chimneys inspect the clean-out regularly to  
ensure that the chimney is free and clear of debris.  
Regardless of the fuel your furnace, fireplace or stove uses,  
your chimney should be inspected from time to time by a  
competent chimney contractor.  
Never try to add a “heat reclaimer” or “automatic flue  
damper” to your gas furnace or water heater. Gas  
installation safety codes prohibit use of these devices as an  
add-on to an existing furnace because of the risks of  
incorrect installation and mechanical failure.  
When using paints, household cleaning supplies or similar  
materials, be sure that you’re using them in a well  
ventilated area.  
- Within 5 ft. (1.5 m)  
of any cooking appliance  
Yellow: Indicates malfunction or “End of Product Life”.  
Refer to Section H.  
- In damp or very humid areas or next to bathrooms with  
showers. Install detectors at least 5 ft. (1.5m) away from

N. Tips for the homeowner  
Energy Conservation and Indoor Air Quality  
Two steps that homeowners take to conserve energy may  
adversely affect indoor air quality.  
Since air leakage can account for as much as 40% of heat  
loss, houses are being made more air tight. Reduced air  
leakage will contribute to higher concentrations of air  
contaminant's from indoor sources and can cause draft  
reversal in the furnace or fireplace chimney when the  
demand for air by fireplaces, furnaces and exhaust fans  
exceeds the air supplied by leakage area and supply ducts.  
Converting from oil to gas, without taking steps to prevent  
chimney deterioration, will increase the risk of chimney  
blockage, draft failure and the associated release of  
alarm, press the  
 Obstructions, or unconventional vent pipe designs  
that can amplify the above situations;  
No, a carbon monoxide alarm only detects carbon  
monoxide. Smoke alarms are still necessary.

circuitry when in use.  
Push the Test/Reset button. Refer to Section H. Do  
not test with car or vehicle exhaust. This method is  
dangerous to you and the pollutants from car or  
vehicle exhaust may damage the alarm.  
IMPORTANT: American Sensors CO alarms CO8 and  
CO8B-D have been designed to operate for 6 years. A  
replacement date label has been placed on the device. On  
the replacement date label write the month and the year,  
corresponding to 6 years/72 months from the installation  
date. Under no circumstances should the alarm be used  
beyond 6 years from installation. The alarm may no longer  
detect CO accurately and should be immediately replaced.  
See Section H for the “End of Product Life “ signal.  
b) Extended operation of unvented fuel-burning appliances  
(range, oven, fireplace, etc.).  
LOW BATTERY:  
c) Temperature inversions that can trap exhaust near the  
ground.  
If your alarm has a low battery, the low battery icon will be  
displayed.  
A malfunctioning unit is indicated by a short single beep  
and flashing yellow LED every 60 seconds. If this occurs,  
reset the unit. If the unit again beeps intermittently, do  
not use this unit.

Step 3  
combustion products into the house. Qualified contractors  
and inspection by the gas company are recommended.  
When the battery is connected, the CO alarm will go  
through a test sequence (the horn will beep 4 times, followed  
by 5 seconds of silence, followed by 4 more beeps - this is the  
alarm pattern that you will hear in the event of an  
emergency). Additionally the red LED will flash with each  
beep and this will be followed by one flash of both green and  
yellow LEDs. Finally the LCD display (where equipped) will  
turn on. If you press the test button this sequence will repeat  
itself. Refer to Section H.  
Carbon monoxide (CO) is odourless, colourless, tasteless and  
very toxic. When inhaled, it produces an effect known as  
chemical asphyxiation. Injury is due to the combining of CO  
with the available hemoglobin in the blood, which lowers the  
oxygen-carrying capacity of the blood. In the presence of  
carbon monoxide, the body is quickly affected by oxygen  
starvation.  
The following symptoms are related to carbon monoxide  
poisoning and should be discussed with all members of the  
household so that you know what to look for:  
For questions about your CO alarm, please contact:

Dirt and Blockage  
B. What is carbon monoxide and why should  
you be concerned?  
Carbon monoxide is a dangerous, poisonous gas. It is often  
referred to as the Silent Killer because it has no odour or taste  
and it can’t be seen. The presence of carbon monoxide inhibits  
the blood’s capacity to transport oxygen throughout the body,  
which can eventually lead to brain damage.  
In any enclosed space (home, office, recreational vehicle or  
boat) even a small accumulation of carbon monoxide can be  
dangerous.  
1-800-387-4219  
Never insulate or try to seal up a draft hood, wind cap or  
exhaust vent on any gas appliance (furnace, hot water  
heater, range, dryer or space heater). Keep your equipment  
area clean. Don’t store anything that could restrict air  
circulation close to equipment.  
It is absolutely essential to your safety that panels and grills  
on the furnace are kept in place and that the fan  
compartment door is closed when the furnace is operating.  
If you have a gas water heater, make sure that combustion  
air openings at the bottom of the tank and the opening  
below the draft diverter (on top of the tank next to the  
flue duct) remain unblocked.  
If you have a gas dryer, the exhaust duct must be vented to  
the outside and have a hood at the end. Check that the  
exhaust system is not blocked by lint or debris and that the  
flapper in the hood moves freely.

Step 4  
While testing the CO alarm, have someone else check that  
the alarm can be heard easily from the sleeping areas, Refer  
to Section H.  
Extreme Exposure (more than 40% COHb):  
Unconsciousness, brain damage, death  
Medium Exposure (15% to 40% COHb): Dizziness,  
drowsiness, vomiting  
Mild Exposure (less than 15% COHb): Headaches,  
running nose, sore eyes, often described as “flu-like”  
symptoms  
What to do after resetting the alarm following an alarm?  
A full continuous alarm within six minutes after reset  
confirms ongoing presence of harmful levels of carbon  
monoxide. If this occurs follow instructions 1 - 2 above.  
What to do after a carbon monoxide problem has been  
corrected?  
After a carbon monoxide problem has been corrected  
reset your alarm by pushing the Test/Reset button as per  
the instructions on Section H.  
Your alarm should be  
tested at least once  
per week by pushing  
the Test/Reset button  
as outlined in Section  
H.  
C. What are the potential sources of carbon  
monoxide?  
Although many products of combustion can cause discomfort  
and adverse health effects, it is carbon monoxide (CO) that  
presents the greatest threat to life.  
A. Indicators  
Your carbon monoxide alarm displays information from four  
sources:  
LCD Display  
Many cases of reported carbon monoxide poisoning indicate  
that while victims are aware they are not well, they become so  
disoriented then are unable to save themselves by either  
exiting the building or calling for assistance.  
Young children and household pets may be the first affected.  
Exposure during sleep is particularly dangerous because the  
victim usually does not awaken.  
For most people, mild symptoms generally will be felt after  
several hours of exposure to 100 ppm of carbon monoxide.  
Higher levels will lead to more severe symptoms or death.

CO is produced by the incomplete combustion of fuels such as  
natural gas, propane, heating oil, kerosene, coal, charcoal,  
gasoline or wood. The incomplete combustion of fuel can occur  
in any device that depends on burning for energy or heat such  
as furnaces, boilers, room heaters, hot water heaters, stoves or  
grills and in any gasoline-powered vehicle or engine (e.g.,  
generator set or lawnmower). Tobacco smoke also adds CO to  
the air you breathe.  
When properly installed and maintained, your natural gas  
furnace and hot water heater do not pollute your air space with  
carbon monoxide. Natural gas is known as a “clean burning”  
fuel because under correct operating conditions the combustion  
products are water vapour and carbon dioxide, which are not  
toxic. (Carbon dioxide (CO2) is also present in the air we  
exhale and is necessary for plant life.) The products of  
combustion are vented from furnaces and water heaters to the  
outside by means of a flue duct or chimney.

If you use exhaust fans, a fireplace or other fuel burning  
heaters or stoves:  
Run exhaust fans for just a minute or two at a time.  
Prolonged use could remove too much air, and it wastes  
heat.  
Do not run power attic vents during the winter or when  
your furnace is on.  
When your fireplace, coal or wood stove is operating, open  
a window and close off warm air registers in the room or  
install a fresh air duct directly to the fireplace or stove so  
that it won’t steal air from your furnace.

Since carbon monoxide moves freely in the air, the suggested  
location is in or as near as possible to sleeping areas of the  
home. The human body is most vulnerable to the effects of  
carbon monoxide during sleeping hours. For maximum  
protection, a carbon monoxide alarm should be located outside  
primary sleeping areas or on each level of your home. The  
diagram suggests ideal locations for alarms in the home. The  
electronic sensor detects carbon monoxide, measures the  
concentration and sounds a loud alarm before a potentially  
harmful level is reached.
