USSC Ashley EC95 Installation, Operation And Maintenance Instructions page 6

There are basically two methods of metal prefabricated chimney installation. One method is to install the chimney inside
the residence through the ceiling and the roof. The other method is to install an exterior chimney that runs up the outside
of the residence.
REMEMBER: Follow the chimney manufacturer's installation instructions and maintain the manufacturer's specified clear-
ance distance.
Additional chimney information is presented throughout this manual. READ IT THOROUGHLY TO BE MORE THOR-
OUGHLY INFORMED.
