Standard Vertical Installation Configurations
Model: Cascade
®
This appliance may be connected to an existing flue or by installing
type "PL" vent pipe (listed to UL 641 and 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 Vent Termination
Requirements on Pages 9 through 11.

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.
Note: See Pages 9 through 11 for Vent Termination Requirements.
