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.
Dirt and Blockage
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

O. COMMONLY ASKED QUESTIONS
Q.What does the alarm sound like?
A.A series of 4 short beeps (loud 85 db sound) with synchronized red LED flashing.
Q.Should I position the unit in a high or low location?
A.Carbon monoxide is virtually the same weight as air and therefore, the alarm protects you in a high or low location.
Q.Will this unit detect smoke and fire?
A.No, a carbon monoxide alarm only detects carbon monoxide. Smoke alarms are still necessary.
Q.How do I test the unit?
A.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.
turn on. If you press the test button this sequence will repeat itself. Refer to Section H.
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.
A. Indicators
Your carbon monoxide alarm displays information from four sources:
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.
C. What are the potential sources of carbon monoxide?
Although many products of combustion can cause discomfort
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:
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

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

and adverse health effects, it is carbon monoxide (CO) that presents the greatest threat to life.
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
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
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.
F. Where should you install the alarm?
Since carbon monoxide moves freely in the air, the suggested location is in or as near as possible to sleeping areas of the
