the sensors to display an inaccurate reading in the
presence of CO.
Do not install CO Alarm in a switch-or dimmer-controlled
outlet.
Do not install in areas where the temperature is colder
than 40 (4.4 ) or hotter than 100 (37.8 ). These
areas include unconditioned crawl spaces, attics, porches
and garages. Extreme temperatures will affect the
sensitivity of the alarm.
Do not install CO Alarm near deep cell large batteries.
Large batteries have emission that can cause the CO
Alarm to perform at less than optimum performance.
Avoid the following:
*Excessive spillage or reverse venting of fuel burning
appliances 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.
3) Simultaneous operation of several fuel burning
appliances competing for limited internal air.
4) Vent pipe connections vibrating loose from clothes
dryers, furnaces or water heaters.
5) Obstructions in or unconventional vent pipe designs
which can amplify the above situations.
*Extended operation of unvented fuel burning devices
(range, oven, fireplace, etc.).
*Temperature inversions which can trap exhaust gases
near the ground.
*Car idling in an open or closed attached garage, or near a
home.
