Where should I install my CO Detector?

Your CO Detector should be installed on a clean surface area inside your home. Make sure you wipe the location before installing your sensor. A good location for a CO Detector is:

At least 12" from any wall if ceiling mounted
At least 6" from the ceiling but not lower than a light switch if wall mounted
Within 10 feet (3m) of a sleeping area
Inside any room that contains a fuel burning appliance (or just outside any room with a fuel burning appliance if the room is not used regularly)

CO Detectors should NOT be installed:

Directly above a sink, cooker, stove or oven
Within five feet of any cooking appliances
Near doors and windows with drafts
In or below a cupboard
In a location where the air flow is obstructed by curtains or furniture
In a location where dirt or dust could collect and block the sensor
Anywhere the sensor can be knocked, damaged or inadvertently removed
On removable ceiling panels

How to mount my CO Detector

Refer to the following diagram and install the mounting base on the ceiling or on the wall (if local ordinances permit) using screw locations as required. Use the two screws and anchors provided. Maneuver the base so the screws are at the elbow of the screw slots and secure.
Fit the detector inside the base by aligning it over the base as shown (detector’s alignment notch should be slightly offset from mounting base tamper release tab), then turn the detector in a clockwise direction until it clicks into place.
