Definition

A chimney flue is a channel or shaft in a chimney for conveying smoke and exhaust gases.

Purpose

The purpose of a chimney flue is to safely direct smoke, gases, and other byproducts of combustion from a fireplace, stove, or furnace out of the building and into the atmosphere, preventing indoor air pollution and potential health hazards.

Examples of Use

1. Fireplaces: Directing smoke and gases from a home fireplace through the chimney flue.
2. Wood Stoves: Venting exhaust from wood stoves via a chimney flue.
3. Furnaces: Using a chimney flue to expel gases from residential or commercial furnaces.

• Draft: The flow of air and gases through the chimney flue, driven by temperature differences.
• Liner: A protective layer inside the flue that improves efficiency and safety.

Notes

• Proper sizing and maintenance of the flue are essential for efficient operation and safety.
