Solve Draft and Smoke Backflow Issues with the Flue Extension Chimney Cap

Prevent Smoke Backflow Between Flues:

In homes with multiple adjacent flues, negative house pressure can cause smoke from one flue to be drawn down into another. Adding the Flue Extender to the upper flue distances its smoke output, keeping it safely channeled upwards and preventing unwanted backflow.

Improve Draft by Raising Flue Height:

Elevating the flue above nearby roofs or structures enhances draft and reduces downdrafts caused by surrounding obstructions. This added height helps the chimney maintain a steady upward airflow, even in areas with challenging wind or structural interference.

Details

304-Alloy Stainless Steel:

Durable, rust-resistant stainless steel construction withstands high temperatures and harsh weather for long-lasting performance.

3/4" Mesh Protection:

Sturdy mesh keeps out debris, animals, and leaves while allowing free airflow, keeping the chimney clean and unobstructed.

Enhanced Draft & Smoke Control:

The flue extension elevates smoke and gases above adjacent flues, boosting draft and reducing smoke backflow for cleaner indoor air.

Efficient Draft Optimization:

Increases upward airflow for a more efficient burn, minimizing smoky backflow and enhancing fireplace performance.

Easy Installation with Adjustable Screws:
Securely fastens with screws on all four sides for a snug, stable fit to the flue tile.

Effective for Multi-Flue Chimneys:
Distances smoke from adjacent downstairs flues to minimize backdraft issues and improve chimney efficiency.

Debris and Moisture Protection:

Stainless steel and mesh barriers prevent water, snow, and debris from entering, reducing moisture damage.

Leak-Proof Connection:

Tight seal prevents leaks and unwanted airflow, protecting against rust and water intrusion.
