These free-standing models may be connected to an existing fl ue or by
installing listed type “PL” vent pipe. If a liner is run all the way to the
top of the existing chimney, the existing fl ue should be sealed with a
steel plate. Start a vertical run with a Tee at the back of the stove. Other
options are illustrated below.
Preferred Installation – Vertical Vent Through the Roof
This venting confi guration allows for the best stove performance. The
vertical pipe promotes natural draft and with the chimney inside the
dwelling, the fl ue gases stay warm, thus rising at a consistent rate.
Note: See Page 12 for Vent Termination Requirements
