IONIZATION SMOKE ALARM,
CARBON MONOXIDE ALARM AND
NATURAL GAS ALARM
WITH BATTERY BACKUP
AND SILENCE FEATURE

ALARM LIMITATIONS AND FUNCTIONS
This Combination Ionization Smoke/Carbon Monoxide (CO)/Natural Gas alarm requires constant
120 VAC power to operate properly.
There are three basic smoke alarm types: IoPhic , Ionization and Photoelectric.
IoPhic is an ionization alarm containing a patent-pending Universal Smoke Sensing Technology.
IoPhic alarms are very effective at detecting fast flaming fires and also respond very quickly to
slow smoldering fires - up to 87% faster than the maximum allowable alarm limit (UL217 Smoldering
Smoke Test on 5/26/2010, Underwriters Laboratories Project #09CA38078).
Ionization smoke alarms are typically more effective at detecting fast flaming fires - fires which consume
combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a
wastebasket, or kitchen grease fires.
Photoelectric smokealarms,onthe other hand, aretypicallymore effectiveatdetectingslow smoldering
fires - fires which burn for hours before bursting into flame. Sources of these fires may include cigarettes
burning in couches or bedding.
Installing IoPhic smoke alarms ensures maximum detection of both types of fires from a single alarm,
while eliminating the need for a combination of ionization and photoelectric smoke alarms.
The enclosed alarm is a Smoke, CO and Natural Gas alarm.

SMOKE ALARMS WILL NOT WORK DURING A LOSS OF POWER. SINCE A SMOKE ALARM WILL
NOT WORK WITHOUT POWER, having an alarm(s) that works from two completely different power
sources, such as an AC direct wire with battery backup smoke alarm, can give you an extra measure of
protection in case of an AC power failure or a dead battery. Battery operated alarms cannot work if the
batteries are missing, disconnected or dead, if the wrong type of batteries are used or if the batteries are
not installed correctly.AC (only) powered alarms cannot work if the AC power is cut off for any reason. If
you are concerned about the limitations of the battery or AC power, install both types of alarms.
CO/NATURALGAS alarms are designed to detect carbon monoxide and natural gases from any source
of combustion or natural gas leakage that reaches their sensor.
USING AN IONIZATION SMOKE ALARM IN A SMOKY AREA, SUCH AS A KITCHEN, OR IN A HIGH
HUMIDITYAREA NEARASHOWER, CAN CAUSE NUISANCE FALSEALARMS. IT IS PREFERABLE
TO USE PHOTOELECTRIC ALARMS IN THESE AREAS. DO NOT TURN OFF THE AC POWER TO
QUIET THE ALARM. A SMOKE ALARM WILL NOT HELP PROTECT YOU IF IT IS NOT POWERED.
Properly locate your alarm to avoid nuisance alarms.
A SMOKE ALARM MAY NOT ALWAYS WARN YOU ABOUT FIRES CAUSED BY CARELESSNESS
AND SAFETY HAZARDS LIKE SMOKING IN BED, VIOLENT EXPLOSIONS, ESCAPING GAS,
IMPROPER STORAGE OF FLAMMABLE MATERIALS, OVERLOADED ELECTRICAL CIRCUITS,
CHILDREN PLAYING WITH MATCHES, NATURAL CAUSES SUCHAS LIGHTNING, ORARSON. FIRE
PREVENTION IS YOUR BEST SAFEGUARD.
INSTALLING SMOKE ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE RATES, BUT
SMOKEALARMSARE NOTASUBSTITUTE FOR INSURANCE. Homeowners and renters alike should
continue to insure their lives and properties.
SMOKEALARMS CANNOT DETECT FIRES IF THE SMOKE DOES NOT REACHTHEM. Smoke from
fires may not reach the sensing chamber and set off the alarm. One alarm should be installed inside each
bedroomorsleepingarea. Do not obstruct airflowaroundthesmoke alarm or placeinareasofobstructed
airflow.
BE AWARE OF VARIOUS SITUATIONS AGAINST WHICH THE SMOKE ALARM MAY NOT BE
EFFECTIVE. For example: (1) Fires where the victim is intimate with a flaming initiated fire; for example,
when a person's clothes catch fire while cooking; (2) Fires where the smoke is prevented from reaching
the alarm due to a closed door or other obstruction or (3) Incendiary fires where the fire grows so rapidly
that an occupant's egress is blocked even with properly located alarms.
SMOKE ALARMS MAY NOT DETECT FIRE ON ANOTHER FLOOR OR AREA OF THE HOME.
Recommendedminimumprotection is atleastone smokealarminevery sleepingareaand every bedroom
on every level of your home. Interconnected smoke alarms may provide earlier warning than stand-alone
smoke alarms since all smoke alarms alarm when one detects smoke.
SMOKEALARMSMAYNOTBEHEARD. Thealarm horninthis alarmmeets orexceedscurrent standards,
but it may not be heard if: (1) the smoke alarm is located outside a closed or partially closed door; (2)
residents recently consumed alcohol or drugs; (3) the alarm is drowned out by noise from stereos, TV's,
air conditioners or other appliances; (4) residents are hearing impaired or (5) if residents are sleeping.
CURRENT STUDIES HAVE SHOWN SMOKE ALARMS MAY NOT AWAKEN ALL SLEEPING
INDIVIDUALSAND THAT IT ISTHE RESPONSIBILITY OF INDIVIDUALS IN THE HOUSEHOLD WHO
ARE CAPABLE OFASSISTING OTHERS TO PROVIDEASSISTANCE TOTHOSE WHO MAY NOTBE
AWAKENED BY THE ALARM SOUND OR TO THOSE WHO MAY BE INCAPABLE OF SAFELY
EVACUATING THE AREA UNASSISTED.
SMOKE ALARMS ARE NOT FOOLPROOF. You must test the smoke alarm weekly to ensure your
continued protection. Smoke alarms cannot prevent or extinguish fires.
COMBINATION CO/NATURAL GAS/SMOKE ALARMS HAVE A LIMITED LIFE. The Combination CO/
Natural Gas/Smoke alarm should be replaced immediately if it is not operating properly. You should
always replace a Combination CO/Natural Gas/Smoke alarm after 7 years.
SMOKEALARMSARE NOT TO BE USED WITH DETECTOR GUARDS UNLESS THE COMBINATION
HAS BEEN EVALUATED AND FOUND SUITABLE FOR THAT PURPOSE.

WHAT YOU SHOULD KNOW ABOUT CO
Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a
cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ
damage in unborn infants with no effect on the mother.
Thefollowingsymptomsare related toCARBONMONOXIDE POISONING andshouldbe discussed
withALL members of the household:
MILD EXPOSURE
Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).
MEDIUM EXPOSURE
Severe throbbing headache, drowsiness, confusion, fast heart rate.
EXTREME EXPOSURE
Unconsciousness,convulsions, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware they
are not well, but they become so disoriented that they are unable to save themselves by either
exiting the building or calling for assistance. Young children and household pets may be the first
affected.
Your combination alarm is designed to detect the toxic CO fumes that result from incomplete
combustion, such as those emitted from appliances, furnaces, fireplaces and auto exhaust.
This product is intended for use in ordinary indoor locations of family living units. It is not designed
tomeasure compliancewith OccupationalSafety andHealthAdministration (OSHA)commercial or
industrial standards. Individuals with medical problems may consider using warning devices which
provide audible and visual warnings for carbon monoxide concentrations under 30 ppm.
IMPORTANT CONSIDERATIONS
YOUR COMBINATION SMOKE, COANDNATURALGAS ALARM HAS BEEN DESIGNED WITH
AN END-OF-SERVICE LIFEALARM WHICH WILLSOUND AFTERAPPROXIMATELY 7 YEARS
OF OPERATION FROM INITIAL POWER UP.
NOTE: MANUFACTURER RECOMMENDS REPLACEMENT OF THIS ALARM 7YEARSAFTER
DATE OF INSTALLATION.
WHAT YOU SHOULD KNOW ABOUT NATURAL GAS
Naturalgas isa fossil fuel which consists primarily of methane.This common energy source is often
used for cooking, home heating and water heating. Natural gas is typically supplied through a main
utilityline connected toyour home. Itis ahighly flammable chemicalcompound.Although it happens
rarely, a natural gas leak can sometimes occur inside the home. This can be dangerous because it
increases the risk of explosion and fire.
Naturalgas is odorless and colorless. When Mercaptanisadded tonatural gasas anodorant, it can
then be detected by smell.Although it can vary greatly, the typical level for detection of the gas by
smell is 25% of the lower explosion limit (LEL). People who have a diminished sense of smell may
notbe able torely on thissafety mechanism.Therefore,installationof this alarmcan be animportant
tooltohelp protectyouand your family.This alarmis calibrated tosound before 20%LELTherefore,
it is possible that you may smell gas before the alarm is activated. If you are not sure which
gas your home uses, contact your utility company.
Natural gas (methane) is typically supplied through a main utility line connected to your home.
Earlywarning isbest achieved by the installation of alarmson allfloors and areas of the household.
WHERE THIS ALARM SHOULD BE INSTALLED
•Install an alarm inside each bedroom where the occupant closes the door while sleeping.
•Analarmshouldbeinstalledinany family living unitcontainingafuel-burningapplianceorfireplace
or having an attached garage.
•An alarm should be centrally located outside of each separate sleeping area in the immediate
vicinityof the bedrooms. Where bedrooms are separatedandaudibility ofthe alarmto occupants
within the bedroom area could be seriously impaired, more than one alarm could be needed.
Page 3

• Locate the first combination alarm in the immediate area of the bedrooms. Try to protect the
escape route as the bedrooms are usually farthest from an exit. If more than one sleeping area
exists, locate additional combination alarms in each sleeping area. If a hall is more than 40 feet
(12 meters) long, install a combination alarm at each end.
• Locate additional smoke alarms to protect any stairway as stairways act like chimneys for
smoke and heat.
• Locate at least one combination smoke alarm on every floor level.
• Locate a smoke alarm in any area where a smoker sleeps or where electrical appliances are
operated in sleeping areas.
• Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting
the smoke alarm on the ceiling in the center of the room places it closest to all points in the room.
Ceiling mounting is preferred in ordinary residential construction. However, in mobile homes, wall
mountingonan inside partitionispreferred to avoidthe thermal barrierthatmay form atthe ceiling.
• When mounting smoke alarm on the ceiling, locate it a minimum of 4" (10cm) from a side wall or
corner (see DiagramA).
• When mounting smoke alarm on a wall, if local codes allow, use an inside wall with the top edge
of the smoke alarm a minimum of 4" (10cm) and a maximum of 12" (30.5cm) below the ceiling/
wall intersections (See DiagramA).
Page 4
Sloped Ceilings (Peaked Ceilings):
Smoke alarms or combination alarms mounted on a peaked ceiling shall be located within 36 in. (914 mm)
horizontally of the peak, but not closer than 4 in. (102 mm) vertically to the peak.
Sloped Ceilings (Shed Ceilings):
Smoke alarms or combination alarms mounted on a sloped ceiling having a rise greater than 1 ft. in 8 ft. (1
m in 8 m) horizontally shall be located within 36 in. (914 mm) of the high side of the ceiling, but not closer
than 4 in. (102 mm) from the adjoining wall surface.
Tray-Shaped Ceilings:
Smoke Alarms or combination alarms shall be installed on the highest portion of the ceiling or on the
sloped portion of the ceiling within 12 in. (305 mm) vertically down from the highest point.
Mobile Home Installation:
For minimum protection, smoke alarms should be installed in compliance with H.U.D. Manufactured Home
Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282. For additional protection,
see Single Story Residence smoke alarm requirements/recommendations for Existing Homes and New
Construction Homes.
Note: For mobile homes built before 1978, install smoke alarms or combination alarms on inside walls
between 4” and 12” from the ceiling (older mobile homes have little or no insulation in the ceiling). This is
especially important if the ceiling is unusually hot or cold.
Install smoke alarms or combination alarms inside each bedroom and in the hallway outside each separate
sleeping area.
Existing Homes:
The NFPArequires smoke alarms or combination alarms on every level and outside each sleeping area in
existing construction. An existing household with one level and one sleeping area is required to have one
smoke alarm.
New Construction Homes and Manufactured Homes:
The NFPArequiresAC-powered, interconnected smoke alarms to be installed inside each bedroom, outside
each bedroom area, and on every level of the home. They also require a minimum of two AC-powered,
interconnected smoke alarms or combination alarms in any new construction home.

In general, install combination Smoke, CO and GasAlarms:
•WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS.
•In or near bedrooms and living areas or wherever you suspect a smoke, gas or CO exposure is
likely.
•On each level of a multilevel home.
IMPORTANT!
Installation in an improper location can affect the sensitive electronic components in this alarm.
Please review WHERE THIS ALARM SHOULD NOT BE INSTALLED (see Page 6).
Not suitable for installation in hazardous locations as defined in the National Electric Code. This
alarm will detect natural gas primarily and carbon monoxide secondarily. Natural gas events will
always take precedence over carbon monoxide events.The word "gas" will be used to specifically
refer to natural gas.
When onAC power, this alarm is designed to act as a continuous monitor. It is not designed for use
as a short-term testing device to perform a quick check for the presence of CO or gas.
BASIC SAFETY INFORMATION
•This combination Smoke, Carbon Monoxide and Natural Gas alarm has separate alarms. This
alarmis notdesigned todetect anyother gas.Carbon monoxideand naturalgas maybe present
in other areas. The Smoke, CO and Natural GasAlarm will only indicate the presence of CO or
natural gas which reaches the sensor.
•Do not paint the alarm. Paint may clog the openings to the sensing chambers and prevent the
unit from operating properly.
•Do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an
emergency. Exposure to the horn at close range may harm your hearing.
Make sure the alarm is not receiving excessively noisy power. Examples of noisy power
could be major appliances on the same circuit, power from a generator or solar power, light
dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power
may cause damage to your alarm.
Find the pair of self-adhesive labels included with this Smoke,CO and GasAlarm.
•On each label, write in the phone number of your emergency responder (such as 911) and a
qualifiedappliance technician.
•Placeone labelnear the Smoke, CO andGasAlarmandthe otherlabel in the "fresh air" location
you plan to go to if the alarm sounds.

This alarm cannot be operated from power derived from a square wave, modified square wave or
modifiedsine wave inverter.Thesetypes ofinverters are sometimesused tosupply power in off-grid
installations,such assolar or wind derived power sources.Thesepower sources may produce high
peak voltages which will damage the alarm.
This unit should receive continuous electrical power. (The battery is meant for emergency
backup only.) Choose an outlet where it can't be accidentally unplugged or switched off by
children. Keep small children away from the unit. Teach them not to play with it or unplug it.
Explain what the alarms mean.
Do not install this alarm into an electrical circuit controlled by a dimmer or switch or ground
fault circuit interrupter.
When testing the alarm, have someone else check that the alarm can be heard easily from the
sleeping areas. The unit should be located where it can wake you if it alarms at night.

RECOMMENDED PLACEMENT:
NOTE: For any location, make sure no door or other obstruction could prevent the smoke, carbon
monoxide or gas from reaching the alarm.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
To avoid causing damage to the unit, to provide optimum protection, and to prevent
unnecessary alarms. Do NOT locate this alarm:
•In garages, kitchens, crawl spaces and unfinished attics.Avoid extremely dusty, dirty or greasy
areas. Installation in these areas could lead to nuisance alarms, may expose the sensor to
substances which could damage or contaminate it, or the alarm may not be heard by people in
other areas of the home, especially if they are sleeping.
•In the garage, vehicle exhaust can contain some carbon monoxide. These levels are higher
whenthe engine is first started.Withinhours ofstartingavehicle and backingit outof thegarage,
the levels present over time can activate the alarm and become a nuisance.
•In the kitchen, some gas appliances can emit a short burst of CO or gas upon startup. This is
normal. If your CO and GasAlarm is installed too close to these appliances, it may alarm often
and become a nuisance.
•Keep alarms at least 20 feet (6m) from the sources or combustion particles (stove, furnace,
waterheater,spaceheater),if possible. In areas where a 20 foot (6m) distance is not possible (in
modular, mobile or smaller homes for example), it is recommended the alarm be placed as far
from these fuel-burning sources as possible. The placement recommendations are intended to
keep these alarms at a reasonable distance from a fuel-burning source and reduce "unwanted"
alarms. Unwanted alarms can occur if an alarm is placed directly next to a fuel-burning source.
Ventilate these areas as much as possible. If you must install the alarm near a cooking or
heating appliance, install at least 5 feet (1.5m) from appliance.
•Curtains or heavy furniture may prevent CO or gas from reaching the sensor.
•Lessthan 12inches (306mm) away from fluorescent lights. Electrical noise can interfere with the
sensor.
•In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or shower,
sauna,humidifier,vaporizer, dishwasher,laundry room, utility roomorothersourceofhighhumidity.
•In very cold or very hot environments or in unheated buildings or outdoor rooms where the
temperature can go below or above the operating range of the alarm. Temperature limits for
proper operation are 40oto 100oF (4.4oto 37.8oC).
•In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air returns or open
windows. Blowing air may prevent CO from reaching the sensors.

•Good ventilation is recommended when household cleaning supplies or similar contaminants
are used.
•Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient
conditions, such as:
Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).
Negative pressure differential resulting from the use of exhaust fans.
Simultaneous operation of several fuel-burning appliances competing for limited internal air.
Vent pipe connections vibrating loose from clothes dryers, furnaces or water heaters.
Obstructions in or unconventional vent pipe designs which can amplify the above situations.

ALARM ORIGINATION: The QUICK FIND®Alarm Origination Feature allows the user to identify
the initiating alarm smoke alarms in an interconnected alarm system. If an interconnected alarm
system is initiated by one of the alarms, when the alarm system exits alarm condition, the user can
identify the initiating alarm by:
a. Pressing and releasing the test button on any alarm in the system.
b. Interconnected alarms will sound and then stop.
c. Theoriginating smokealarm will continue to sound 60 seconds to allow ample timeto quickly
find originating alarm.
IF YOUR CO AND GAS ALARM SOUNDS
WHAT TO DO IF CARBON MONOXIDE IS DETECTED:
Actuation of your COAlarm indicates the presence of carbon monoxide (CO), which can kill you. In
other words, when your COAlarm sounds, you must not ignore it!
Someindividuals are more sensitive to CO than others, including people with cardiacor respiratory
problems, infants, unborn babies, pregnant mothers or elderly people can be more quickly and
severely affected by CO. Members of sensitive populations should consult their doctors for advice
on taking additional precautions.
If you hear the alarm horn sound 4 beeps, a 5 second pause (and then repeat),
carbon monoxide has been detected. Evacuate everyone from the building.

CO AND NATURAL GAS ALARM LIMITATIONS
Alarms have limitations. Like any other electronic device, Smoke, CO and Natural Gas alarms are
notfoolproof.
Smoke, CO and Natural Gas alarms have a limited operational life. Your alarm must be tested
weekly, because it could fail to operate at any time. If your aAlarm fails to test properly, or if its self-
diagnostictest reveals amalfunction, immediatelyhave the unitreplaced (seelast page for warranty
information).
Smoke, CO and Natural Gas alarms can only sense CO which reaches the alarm's sensor. Carbon
monoxide may be present in other areas without reaching the alarm.
COor gascould bepresent onone levelof thehome andnot reachthe alarminstalledon adifferent
level. For example, CO or gas in the basement may not reach an alarm on the second level, near
thebedrooms. For thisreason, werecommend you providecomplete coverageby placing aSmoke,
CO and Natural Gas alarm on every level of the home.
Smoke,COand NaturalGasalarms are nota substitute forproperty,disability,lifeor other insurance
of any kind.Appropriate coverage is your responsibility.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances, such as; heaters, gas or wood burning fireplaces, gas kitchen ranges
or cooktops, gas clothes dryers.
Damaged or insufficient venting; such as; corroded or disconnected water heaters, vent pipes,
leakingchimneys,pipes or fluesor cracked heatexchangers, blocked orcloggedchimney openings.
Improper use of appliances/devices; operating a barbeque grill or vehicle in an enclosed area
(such as a garage or screened porch).
Transient CO Problems: "transient"or on-again/off-againCOproblemscan be caused by outdoor
conditions and other special circumstances.
BACKUP BATTERY REPLACEMENT
DisconnectAC power before changing battery. Shock hazard exists ifAC power is miswired.
Thealarm usesa 9Voltbattery.Thebattery should last forat leastone yearunder normal operating
conditions.Thealarm has a low battery indicator, an audible beep or chirp. It will operate at approx.
40 second intervals for a minimum of 7 days. When this indication occurs, replace the battery with
anAlkaline type (Energizer #522, Duracell #MN1604), or Lithium type (Ultralife U9VL-J) from your
localretailer.
LITHIUM Battery Models only - The LITHUM battery is warranted to last for 10 years under normal
operating conditions. Replace the battery with only LITHIUM type: (ULTRALIFE: U9VL-J.

DEVELOP AND PRACTICE APLAN OF ESCAPE
BASICS OF ESCAPE PLAN
o Make a floor plan indicating all doors and windows and at least two escape routes from each
room. Second story windows may need a rope or chain ladder.
o Haveafamily meeting anddiscuss your escapeplan, showing everyonewhatto do incase of fire.
o Determine a place outside your home where all of you can meet if a fire occurs.
o Familiarizeeveryone with the sound of the smokealarm andtrain themto leaveyour home when
they hear the sound.
o Identifychildren's bedrooms withred stickersplaced in theupper leftcornerof the windows.They
are available from your local fire department.
o Practice a fire drill at least every six months. Practice allows you to test your plan before an
emergency. You may not be able to reach your children. It is important they know what to do!
REPAIRS AND SERVICES
Ifthe smokealarm is defective in any way, do not tamper with the smoke alarm. Return the alarm for
servicing. (See warranty for instructions or in-warranty returns.) There will be a service charge for
repairing out of warranty alarms.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient
conditions, such as:
•Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).
•Negative pressure differential resulting from the use of exhaust fans.
•Simultaneous operation of several fuel-burning appliances competing for limited internal air.
•Vent pipe connections vibrating loose from clothes dryers, furnaces or water heaters.
•Obstructions in or unconventional vent pipe designs which can amplify the above situations.
2. Extended operation of unvented fuel-burning devices (ranges, ovens, fireplaces).
3. Temperature inversions which can trap exhaust close to the ground.
4. Acar idling in an open or closed attached garage or near a home.
HOW CAN I PROTECT MY FAMILY FROM CO POISONING?
This alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before
carbon monoxide levels become threatening to the average, healthy adult.
An alarm is not a substitute for proper maintenance of home appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
•Cleanchimneys andflues yearly.Keep them free of debris, leaves and nestsfor proper air flow.
Also,have aprofessional check for rust and corrosion, cracks or separations.These conditions
can prevent proper air movement and cause backdrafting. Never "cap" or cover a chimney in
any way that would block air flow.
•Test and maintain all fuel-burning equipment annually. Many local gas or oil companies and
HVAC companies offer appliance inspections for a nominal fee.
•Makeregular visual inspections of allfuel-burning appliances. Check appliances for excessive
rust and scaling.Also check the flame on the burner and pilot lights. The flame should be blue.
A yellow flame means fuel is not being burned completely and CO may be present. Keep the
blowerdoor on thefurnace closed.Use vents or fanswhen theyare available onall fuel-burning
appliances.Make sureappliances arevented tothe outside.Donot grillor barbecueindoors or
in garages or screen porches.
•Checkfor exhaust backflow from COsources. Checkthe drafthood onan operating furnace for
a backdraft. Look for cracks on furnace heat exchangers.
•Check the house or garage on the other side of a shared wall.
•Keepwindows and doorsopen slightly. Ifyou suspectthat CO is escaping intoyour home,open
a window or a door. Opening windows and doors can significantly decrease CO levels.

alarm for servicing. (See warranty for instructions or in-warranty returns.) There will be a service
charge for repairing out of warranty smoke alarms.
WHAT TO DO WHEN THE ALARM SOUNDS
o Leave immediately by your plan of escape. Every second counts, so don't waste time getting
dressed or picking up valuables.
o In leaving, don't open any inside door without first feeling its surface. If hot, or if you see smoke
seepingthrough cracks, don't open that door! Instead, use your alternate exit. If inside door is
cool,place yourshoulder against it, open it slightly and be ready to slam it shut if heat and smoke
rush in.
o Stay close to the floor if air is smoky. Breathe shallowly through a cloth, wet if possible.
o Once outside, go to your selected meeting place and make sure everyone is there.
o Call the fire department from your neighbor's home – not from yours!
o Don't return to your home until fire officials say that it is all right to do so.
