What is the minimum clearance for a listed duct furnace from adjacent combustible materials?

The minimum clearance for a listed duct furnace from adjacent combustible materials is specified as 6 inches to ensure safety and compliance with building codes and manufacturer guidelines. This clearance requirement is crucial for preventing heat-related hazards, such as ignition of surrounding materials, which could lead to fires. The 6-inch distance creates a buffer that allows for safe heat dissipation and protects combustible materials from excessive temperatures that the furnace may generate during operation. By adhering to this clearance specification, technicians can help maintain safe operating conditions in both residential and commercial installations.
