more information about CO safety and this 
equipment. Make sure that motor vehicles 
are not, and have not been, operating in an 
attached garage or adjacent to the residence.
This information is available as a label provided 
in the box. Stick it in a spot where everyone can 
see it, like the refrigerator.
THE FOLLOWING CONDITIONS CAN RESULT IN 
TRANSIENT CO SITUATIONS
1. Excessive spillage or reverse venting of fuel 
burning appliances caused by:
  I) 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).
  II) Negative pressure differential resulting 
from the use of exhaust fans. 
  III) Simultaneous operation of several fuel 
burning appliances competing for limited 
internal air.
  IV) Vent pipe connection vibrating loose from 
clothes dryers, furnaces, or water heaters.
  V) Obstructions in or unconventional vent pipe 
designs which amplify the above situations.
2. Extended operation of unvented fuel burning 
devices (range, oven, fireplace, etc.).
3. Temperature inversions which can trap 
exhaust gases near the ground.
4. Car idling in an open or closed attached 
garage, or near a home.
5. NEVER bring a charcoal grill inside and 
ALWAYS operate a portable generator 
outside, a safe distance from the house, 
and well away from windows.
WHAT TO DO IN CASE OF A CARBON 
MONOXIDEALARM
 WARNING
Actuation of your CO alarm indicates the 
presence of carbon monoxide (CO) which 
can KILL YOU.
If alarm signal sounds:
1) Operate reset/silence button (Press  
Nest button);
2) Call your emergency services [fire dept. or 911];
PHONE NUMBER:
3) Immediately move to fresh air – outdoors or 
by an open door/window. Do a head count to 
check that all persons are accounted for. Do 
not reenter the premises nor move away from 
the open door/window until the emergency 
services responders have arrived, the 
premises have been aired out, and your alarm 
remains in its normal condition.
4) After following steps 1 – 3, if your alarm 
reactivates within a 24-hour period, repeat steps 
1 – 3 and call a qualified appliance technician
PHONE NUMBER:
  to investigate for sources of CO from 
fuel burning equipment and appliances, 
and inspect for proper operation of this 
equipment. If problems are identified 
during this inspection have the equipment 
serviced immediately. Note any combustion 
equipment not inspected by the technician 
and consult the manufacturers’ instructions, 
or contact the manufacturers directly, for 
FIRE SAFETY PRECAUTIONS
CREATE AN ESCAPE PLAN TO PRACTICE
Be prepared when your smoke/CO alarm 
sounds its alarm. Develop a family escape 
plan, discuss it with all household members, 
and practice it regularly.
• Make sure everyone is familiar with the sound 
of your smoke/ CO alarm and explain what the 
sound means.
• Determine TWO exits from each room and 
have an escape route to the outside from 
each exit.
• Teach all the members in your household to 
check doors for heat with the back of your 
hand before opening them, and to use the 
alternate exit if the door is hot. Make sure 
they do not open the door if it is hot.
• Teach household members to crawl along 
the floor to avoid dangerous smoke, fumes 
and gases.
• Determine a safe meeting place for all 
household members to regroup at outside 
the building.
PRACTICE FIRE SAFETY
Practice your escape plan at least twice a year, 
making sure that everyone is involved – from kids 
to grandparents. Practice the escape plan with 
children, including holding one at night when they 
are sleeping. If children or others do not wake 
up to the sound of the smoke alarm, or if there 
are infants or family members with mobility 
limitations, make sure that someone is assigned 
to help them for the fire drill and in the event 
of an emergency. Current studies have shown 
smoke alarms may not awaken all sleeping 
individuals, and that it is the responsibility of 
individuals in the household that are capable of 
assisting others to provide assistance to those 
who may not be awakened by the alarm sound, 
or to those who may be incapable of safely 
evacuating the area unassisted.
WHAT TO DO IN CASE OF FIRE
• Get out now.
• Don’t panic; stay calm.
• Operate your safety plan as previously 
planned.
• Alert small children in the home and those 
who may need extra assistance.
• Leave the building as quickly as possible. 
Touch doors with the back of your hand and 
make sure they are not hot before opening 
them. Use an alternate exit, if necessary. 
In case of smoke, crawl along the floor, and 
DO NOT stop to collect anything. Close the 
doors behind you.
• Meet at a pre-arranged meeting place outside 
the building.
• Once outside, do a head count, and call the 
fire department.
• DO NOT reenter the house, unless a fire 
official says it’s safe to reenter.
