Lennox Hearth II-T C FS - Manual (Page 18)

INSTALLATION
Standard Vertical Installation Configurations - Model: Advantage II-T C FS - These freestanding models may be con-
nected to an existing unused flue or by installing type “PL” vent pipe (listed to UL 641 & ULC S609). 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. Note: See page 13 for Vent Termination Requirements.

Vertical Vent Into A Masonry Flue
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.
