Spark Arresters/Chimney Caps/Rain Caps

As of July 1, 2011 all homes in California that burn or use fossil fuels must have a Carbon monoxide detector.  Required by the Senate bill the detector must have an audible warning when carbon monoxide is detected.  It must be battery powered, or if it is plugged into an electrical outlet, it must have a battery backup.  The detector must also be certified by national testing laboratories, such as Underwriter’s Laboratories.
