WALL LOCATION:
Mount the alarm at least
3 feet (usually 5 – 6 feet)
from the floor.
Figure 1:
Recommended CO alarm wall
mounting location is 5 to 6 feet from floor
5.3 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.
5.4 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.
3 Simultaneous operation of several fuel burning appliances
competing for limited internal air.
4 Vent pipe connections vibrating loose from clothes dryers,
