Standard Vertical Installation Configurations
Model: Montage™ 3FS
This free-standing model may be connected to an existing flue 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 flue 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 configuration allows for the best stove performance. The
vertical pipe promotes natural draft and with the chimney inside the
dwelling, the flue gases stay warm, thus rising at a consistent rate.
