This comprehensive guide will explore everything you need to know about LOPI flue pipes, including their types, installation tips, maintenance, and advantages.

What is a LOPI Flue Pipe?

A LOPI flue pipe is a specialized pipe system designed to vent smoke and combustion gases safely from wood or gas stoves to the outside atmosphere. These pipes are essential for ensuring that your stove operates efficiently and safely, preventing smoke and harmful gases from entering your home.

LOPI, a trusted name in the heating industry, manufactures flue pipes that meet stringent safety standards and are compatible with a variety of stove types. Their products are known for:

Planning the Layout

  • Determine the number of bends required.

  • Ensure the flue pipe route avoids combustible materials.

Preparing the Stove Connection

  • Connect the stove collar to the first section of the flue pipe.

  • Use high-temperature silicone or gaskets to ensure a tight seal.

Installing Vertical Sections

  • Assemble pipe sections vertically, ensuring each section fits snugly.

  • Use support brackets if needed to prevent sagging.

Installing Elbows and Horizontal Sections

  • Use elbows for directional changes.

  • Maintain a minimum rise of 6 inches per horizontal foot to ensure proper draft.

Securing the Exterior Termination

  • Install a chimney cap to prevent rain, debris, and birds from entering.

  • Ensure the flue extends at least 2 feet above the roofline or 3 feet above any nearby structure.

Inspection

  • Check all joints for tightness.

  • Ensure clearances to combustibles are maintained.

  • Test the stove for proper draft before regular use.

Inspect for Damage

  • Check for cracks, corrosion, or loose connections.

  • Replace any damaged sections immediately.

Check Draft

  • Ensure the flue maintains a proper draft to prevent smoke spillage.

  • If draft issues occur, consider adjusting pipe height or cleaning the chimney.

Avoid Excessive Moisture

  • Keep the flue dry to prevent rust, especially for single-wall pipes.

  • Use a chimney cap to protect against rainwater.
