When installing a wood stove pipe, it’s essential to adhere to local building codes and the manufacturer’s installation guidelines. Many codes specify maximum allowable angles and lengths for horizontal runs of the stovepipe. Here are some general recommendations:

  • Vertical Runs: Ideally, a vertical run should be as straight as possible to enhance draft.
  • Horizontal Runs: If a horizontal run is necessary, it should not exceed 3 feet in length and must be installed with a slight upward slope (typically 1/4 inch per foot) to maintain proper flow.
  • Bends: If bends are necessary, they should be limited to 30 degrees or less to prevent significant airflow restrictions.

Factors Influencing Pipe Installation

Several factors can influence how the wood stove pipe is installed:

  • Stove Design: Different stove models may have specific requirements for pipe orientation.
  • Home Layout: The physical layout of the home may necessitate bends or horizontal runs.
  • Height of the Chimney: The height of the chimney can impact the draft. A taller chimney typically enhances draft but may require additional considerations for horizontal runs.
