Can I use flexible pipe for wood stove chimney installations?

April 5, 2026

Quick Answer

Flexible pipe can be used for wood stove chimney installations, but it's essential to follow specific guidelines and manufacturer recommendations to ensure safe and proper functioning.

Choosing the Right Flexible Pipe

When selecting a flexible pipe for wood stove chimney installations, look for pipes made from materials like stainless steel, aluminum, or fiberglass. These materials offer durability and resistance to high temperatures. Ensure the pipe is specifically designed for wood stove chimney applications and meets the International Residential Code (IRC) and National Fire Protection Association (NFPA) standards.

Installation Considerations

When installing flexible pipe, it’s crucial to follow the manufacturer’s instructions and local building codes. Typically, flexible pipe is used for connections between the wood stove and the chimney, or for navigating tight spaces. Use a minimum of 10 inches of flexible pipe for each bend, and ensure the pipe is securely fastened to the surrounding structure to prevent damage or disconnection.

Safety Precautions

When working with flexible pipe, always follow safety guidelines to prevent accidents and ensure a safe installation. Wear heat-resistant gloves and protective eyewear, and ensure the work area is well-ventilated. Never use flexible pipe in place of rigid pipe, as this can compromise the chimney’s draft and potentially lead to safety hazards. Regularly inspect the flexible pipe for signs of damage or wear, and replace it as needed to maintain a safe and functioning chimney system.
