Specialty Flue Extension with Designer Lid
Increase height and draft with the Specialty Flue Extensions. Securely fastened to the uppermost clay liner, these caps can also increase the vertical distance among flues in a multi-flue chimney, reducing the likelihood of smoke being drawn into a downstairs flue. Due to a variety of sizes and options, each Specialty Flue Extension is made custom per order and is non-returnable.

Fabrication time is currently 1 week due to item popularity. Powder coating adds 1 week to the timeline (and is worth the wait!).
- 22" Flue Extension increases height by 1 foot.
- 34" Flue Extension increases height by 2 feet.
The Specialty Flue Extension is designed to mount to chimney tile. It can be converted to a Crown Mount by adding a Crown Mount Adapter. You will need this if there is no existing flue tile extending from the chimney top or the flue tile is too short. Note: Must choose "Bolt On" style Specialty Flue Extension with the Crown Mount Adapter.
