Installation Instructions (cont.)
• Ensure that all vents of the unit are unobstructed.
• Do not install in dead air spaces such as peaks of vaulted
ceilings, or gabled roofs.
• Do not install in turbulent air from ceiling fans.
Do not place near fresh air vents or close to doors and
windows that open to the outside.
• Keep the CO alarm away from excessively dusty, dirty, or
greasy areas such as kitchens, garages and boiler or utility
rooms. Dust, grease and household chemicals can affect
the sensor.
• Keep out of damp and humid areas such as the bathroom.
Avoid spraying aerosols near the CO alarm.
• Do not install in areas where the temperature is below
40˚F (4.4˚C) or hotter than 100˚F (37.8˚C).
• Do not place behind curtains or furniture. CO must be able
to reach the sensor for the unit to accurately detect carbon
monoxide. NEVER place the CO alarm flat on a table top
or similar surface.
• Be aware that certain conditions can result in transient
CO situations, such as: 1) Excessive spillage or reverse
venting of fuel burning appliances caused by outdoor
ambient conditions, such as: i) Wind direction and/or
velocity, including high gusts of wind.
vent pipes (cold/humid air with extended periods between
cycles). ii) negative pressure differential resulting from the
use of exhaust fans. iii) Simultaneous operation of several
fuel burning appliances competing for limited internal air.
iv) Vent pipe connections vibrating loose from clothes
dryers, boilers or water heaters. v) Obstructions in or
unconventional vent pipe designs which can amplify the
above situations. 2) Extended operation of unvented fuel
burning devices (cooker, oven, fireplace, etc.).
3) Temperature inversions which can trap exhaust near the
ground. 4) Car idling in open or closed garage, or near home.
