LOCATIONS TO AVOID
: Nuisance alarms are caused by placing units
where they will not operate properly. To avoid nuisance alarms, do not
place units:
– Within 5 feet (1.5m) of any cooking appliance or furnace.
– Near an open window or door, because the fresh air entering the
opening may delay CO from reaching the alarm.
– In damp or very humid areas or next to bathrooms with showers.
Install detectors at least 10 feet (3 meters) away from bathrooms.
– 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 -20° F to 120° F ( -29° C to 49° C); Operating Humidity is 10 – 95% RH.
– Good ventilation is recommended when household cleaning supplies
or similar contaminants are used.

CONDITIONS WHICH CAN RESULT IN TEMPORARY CO SITUATIONS
:
5.4.1 Excessive spillage or reverse venting of fuel burning appliances
(woodstoves, etc) caused by outdoor ambient conditions, such as:
1
Wind direction and/or velocity, including high gusts of wind.
Heavy air in the vent pipes (cold/humid air with extended
periods between cycles).
2
Negative pressure differential resulting from the use of exhaust
fans, lack of combustion air entering building or dwelling.
