Most antique wood stoves have not been approved by Underwriters Laboratories Inc. (UL). The UL is a non-government, non-profit organization that tests and certifies products for safety. Manufacturers are not required to submit their products for testing. However, some municipalities require that only electrical or heating components that are UL approved be used in their areas. Even if your stove has not been approved, most modern day chimney, stove pipe and other wood stove accessories have, making installation of an older stove safer.
