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.

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:
