Is your wood stove EPA-certified?
If your wood stove (free-standing or insert) was manufactured prior to 1993, it probably is not EPA-certified. If it was manufactured in 1993 or later there should be a label on your device indicating EPA certification. This can only be done at the manufacturer level. If there is no label present, the device has not been tested for emissions levels in an approved laboratory setting, and therefore is not EPA-certified.
