What is the minimum distance all around a furnace, between the furnace and combustibles?

8 inches
18 inches
1 inch
12 inches

The correct answer is: 1 inch

The minimum distance all around a furnace, typically set at 1 inch, is critical for safety and proper operation. This distance ensures adequate airflow for combustion and prevents overheating or igniting any combustibles that might be nearby. Setting this distance too close can result in increased fire hazards or hinder the furnace's ability to exhaust gases effectively, which might lead to carbon monoxide buildup or system failure. In many codes and regulations, including those from the National Fire Protection Association (NFPA) and local building codes, maintaining this specific clearance helps ensure that equipment operates safely and efficiently while minimizing risks associated with flammable materials. Overall, the 1-inch clearance is designed to protect both the furnace and surrounding materials, making it a crucial guideline for construction and maintenance practices.
