LOCATIONS TO AVOID
• Near an open window or door with fresh air
entering the opening and delaying the CO
from reaching the alarm.
• In damp or very humid areas or next to
bathrooms with showers; install detectors at
least 10 ft (3 meters) away from bathrooms.
• In very cold or very hot environments or in
unheated buildings or outdoor rooms where
the temperature can drop below or rise
above the operating range of the alarm;
temperature limits for correct operation are
40° to 100°F (5° to 38°C).
• In areas where nuisance alarms can result
because CO alarms are placed where they
cannot operate correctly such as:
— Within 5 ft (1.5M) of any cooking appli-
ance or furnace.
— In areas of limited ventilation where
household cleaning supplies or similar
contaminants are used.
CONDITIONS THAT CAN RESULT IN TEMPORARY CO
SITUATION
• Excessive spillage or reverse-venting of
fuel-burning appliances from outdoor
ambient conditions such as:
— Wind direction and/or velocity, including
high gusts of wind; heavy air in vent
pipes (cold /humid air with extended
periods between cycles).
— Negative pressure differential resulting
from using exhaust fans.
— Simultaneous operation of several fuel-
burning appliances that compete for lim-
ited internal air.
