(102 mm) and 12 inches (305 mm) from
the wall/ceiling line.
• When installing on the ceiling, place the
alarm as close to the center as possible.
• In either case, install at least 4 inches
(102 mm) from where the wall and ceiling

WHERE NOT TO INSTALL
THIS ALARM
Do NOT locate this smoke/CO alarm:
• In garages, kitchens, furnace rooms, crawl
spaces and unfinished attics. Avoid
extremely dusty, dirty or greasy areas.
• Closer than 20 feet (6 meters) from a fur-
nace or other fuel burning heat source, or
fuel burning appliances like a water heater.
• Where combustion particles (formed when
something burns) are produced. Avoid
poorly ventilated kitchens, garages, and
furnace rooms. Keep this smoke/CO alarm
at least 20 feet (6 meters) from sources of
combustion particles (stove, vehicle,
furnace) whenever possible.
• Within 5 feet of any cooking appliance.
In air streams near kitchens. Air currents
can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This alarm should
be at least 10 feet (3 meters) from a shower,
sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source
of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open
windows. Blowing air may prevent CO or
smoke from reaching the sensors.
