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.

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

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:

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.

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.

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.

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
