A CO Alarm is useful only if it works. The following illustration explains proper maintenance: WARNING: K. 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 odor or taste and it cannot 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. Do not paint over this CO alarm.

Test/Reset button 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. Confining or enclosing gas-fired equipment If you have partitioned off your furnace and water heater, you may need additional ventilation. Danger Signs Stuffy, stale or smelly air, back drafts and soot from a fireplace or furnace chimney usually means your home needs more air for proper combustion and healthy living. For gas-fired equipment, mostly yellow (rather than clear blue) burner flames, a pilot light that keeps going out, or a smell of gas indicate trouble. Turn off the equipment and contact your gas company emergency service. Additional Safety Tips Have your fuel-burning equipment checked periodically for safety and efficiency by a qualified service technician. 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-yourselfers” 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. Following sensible maintenance and safety procedures in the home will give you fuel savings without endangering your health. Q. COMMONLY ASKED QUESTIONS Q. What does the alarm sound like? A. The alarm signal consists of 4 constantly repeating rapid beeps every 5 seconds, with the red LED light flashing every time the alarm horn beeps. Q. Should I locate 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. Is it normal that the unit is slightly warm? A. Yes, your alarm may be slightly warm due to a transformer located inside. Q. Will this unit detect smoke or 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.
