A connector to a chimney flue shall be at least how many inches above the lowest portion of the interior of the flue?

• A. 6 Inches Above
• B. 12 Inches Above
• C. 18 Inches Above
• D. 24 Inches Above

Answer: (B)

The key idea here is proper clearance for a chimney connector entering a flue. Requiring the connector to be at least twelve inches above the lowest interior portion of the flue protects against buildup and condensate at the bottom interfering with the connection, which reduces fire risk and makes cleaning and inspection easier. It also helps ensure the draft remains reliable by keeping the connector well inside the flue’s pathway rather than near the bottom where deposits and moisture tend to accumulate. In practice, this specific twelve-inch distance is the code-mpecified minimum, rather than allowing a smaller or larger amount.
