The Board will grant to qualified applicants a license in the specialty of installing heaters. The Board designates such a license as a "classification C-39" license. A person who holds a classification C-39 license may install devices for the heating of buildings, including wood-burning devices and their appurtenances. This license does not authorize the holder to install piping, ducting and equipment for transmitting the heated air or water produced by the devices.
