Residential Building Inspector B1Building Planning and Life SafetyMedium
An inspector is reviewing the plans for a new residential dwelling. The plans indicate the installation of a solid-fuel-burning appliance. What is the minimum required clearance from the appliance to combustible materials on the side and rear, when tested and listed for 6-inch (152 mm) clearance?
- A6 inches (152 mm)
- B4 inches (102 mm)
- C2 inches (51 mm)
- D12 inches (305 mm)
Show answer & explanationAnswer & explanation
Correct answer: A. 6 inches (152 mm)
Solid-fuel-burning appliances generate significant heat, and maintaining proper clearance to combustible materials is crucial for fire safety. The listed clearance directly dictates the minimum required separation.
Why the other options are wrong
- B. This clearance is too small for an appliance listed for 6 inches.
- C. This clearance is too small for an appliance listed for 6 inches.
- D. While safer, this exceeds the minimum requirement for an appliance listed for 6 inches.
Solid-Fuel Appliance Clearance
Solid-fuel-burning appliances must maintain specific minimum clearances from combustible materials as determined by their listing and labeling.
- Clearance prevents ignition of adjacent combustible surfaces.
- Minimum clearances are established by testing standards.
- Always follow the manufacturer's installation instructions and listing.
Memory trick: Hot appliances need space, listed values keep fire at bay.
