1. RECOMMENDED LOCATION OF MONITORS
CO poisoning can happen anywhere in the building.
CO monitors should be installed onto an interior wall,
five feet off the floor, and on every conditioned level
of the building. At the minimum, install CO monitors:
1. Inside or near every area or room that may be
occupied.
2. To cover every 1000 square feet of vertically
unobstructed space.
3. Inside, near access door, of maintenance room
that contains combustion equipment or
appliances, such that an alarm signal will be
heard before anyone enters the room.
4. Inside any room where someone may sleep with the door closed, or that is occupied
by someone who may be hypersensitive to CO, such as older adults, young children,
pregnant women or persons with medical conditions.
CO detection is best achieved by the installation of CO monitors in all heated/conditioned
areas and rooms of the building.
Do not install a CO monitor:
1. Inside of a garage, cleaning supply
room, bath room, dusty area or
unconditioned space. The
monitor’s operation temperature
range is 40oF to 100oF.
2. Within five feet of a combustion or
cooking appliance including a
furnace, boiler, water heater,
space heater, oven or range.
3. Within five feet of a window or exterior door.
4. Within three feet of a room with a bathtub, shower, spa or washer/dryer.
5. Within one foot of a wireless device.
6. Where the monitor would be obstructed by furniture drapes, etc.
7. In a hazardous area, as defined in the National Electrical Code.
