According to the Florida Building Code, what is the maximum distance a change in chimney flue size or shape can be from the floor or ceiling component?

  1. 4 inches

  2. 6 inches

  3. 8 inches

  4. 10 inches

The correct answer is: 6 inches

The correct answer is based on specific provisions outlined in the Florida Building Code, which seeks to establish clear and safe guidelines for chimney constructions. The code stipulates that the maximum allowable distance for a change in chimney flue size or shape from the floor or ceiling component is 6 inches. This regulation serves to ensure that the transition between different sizes or shapes of a chimney flue does not create traps or obstructions, which could inhibit proper draft and potentially lead to fire hazards or the accumulation of dangerous gases. While the other distances mentioned in the choices are significant, they exceed the code's limit, which is designed to promote safety and efficiency in chimney systems. Keeping changes in flue size or shape within this 6-inch limit also helps maintain structural integrity throughout the installation.
