External Wood Burning Stove Flue: What You Need to Know

An external wood burning stove flue, also known as an outdoor flue or chimney, is a critical component of wood stove installations where the stove is located outside, like in a porch or covered patio. This article provides clear and concise information for both technical and non-technical audiences about external wood burning stove flues.

Understanding the External Wood Burning Stove Flue

An external flue is designed to vent the smoke and combustion byproducts produced by a wood burning stove to the outdoors. The principles governing its construction and functionality are similar to those of an indoor chimney or flue. Here’s what you need to know:

Materials: External flues are typically made of stainless steel or another durable, weather-resistant material. This ensures the flue’s longevity and ability to withstand outdoor conditions.

Clearances: Just like indoor flues, outdoor flues must maintain clearances from combustible materials like walls, roofs, and overhangs. Always adhere to local building codes and manufacturer recommendations.

Components: An external flue comprises sections of flue pipe, typically insulated to improve draft and reduce creosote buildup. It is often extended upward through a chimney cap to prevent rain and debris from entering.

Installation Steps for an External Flue

Installing an external flue for your wood burning stove is a precise process. Here’s a straightforward guide:

  1. Plan the Route: Determine the path the external flue will take. Ensure it complies with clearances and local regulations.

  2. Select the Flue Material: Choose a weather-resistant material like stainless steel for the flue. Ensure all components are designed for outdoor use.

  3. Connect the Stovepipe: Attach the stovepipe to your wood stove’s flue collar. Follow manufacturer guidelines for clearances and secure connections.

  4. Connect the External Flue Sections: Connect the external flue sections, ensuring they are sealed tightly to prevent leaks.

  5. Extend the Flue: Extend the flue above the roofline using additional sections. This minimizes the risk of downdrafts and maximizes the efficiency of the flue.

  6. Install a Chimney Cap: Place a chimney cap at the top of the flue to keep out rain, animals, and debris.

  7. Adhere to Local Regulations: Always comply with local building codes and regulations throughout the installation process.

Benefits of an External Flue

Using an external flue for your wood burning stove offers several advantages:

  1. Reduced Indoor Smoke: An external flue eliminates the need for indoor chimney runs, which can reduce the risk of indoor smoke or odors.

  2. Increased Safety: Outdoor flues minimize the risk of fire hazards associated with indoor installations.

  3. Enhanced Efficiency: With the flue located outside, the wood stove can operate more efficiently and draw better.

Conclusion

An external wood burning stove flue is a practical solution for outdoor wood stove installations. By following the guidelines for its construction and adhering to local regulations, you can enjoy the warmth and ambiance of a wood stove in your outdoor space safely and efficiently.
