The hearth extension must extend how many inches beyond each side of the fireplace opening if the opening is less than 6 square feet?

6 inches
8 inches
10 inches
12 inches

The correct answer is: 8 inches

For a fireplace opening that is less than 6 square feet, building codes and safety standards typically require the hearth extension to extend a specified distance beyond the sides of the fireplace. An extension of 8 inches beyond each side of the fireplace opening is the standard requirement in this scenario. This distance is intended to provide adequate protection against heat and embers escaping from the firebox, helping to prevent potential fire hazards. By extending 8 inches on either side, the hearth acts as a barrier, ensuring that any stray sparks or heat do not ignite nearby materials, which is critical for maintaining safety in the home. It also takes into consideration the average length of logs or other burning materials that may protrude during use. Adhering to this standard helps ensure compliance with safety regulations and promotes the overall effectiveness of the fireplace system.
