• A. 4 inches
• B. 6 inches
• C. 8 inches
• D. 10 inches

Answer: (B)

The minimum clearance above grade required for floor furnaces is 6 inches. This requirement is critical for ensuring safe operation and maintenance of the furnace. By maintaining this clearance, it helps to prevent the potential for moisture accumulation under the unit, which could lead to corrosion or other damage. Additionally, this space allows for proper airflow and ventilation, which are essential for the efficient functioning of the furnace as well as for safety, reducing the risk of fire hazards. Adequate clearance also facilitates easier access for servicing and repairs, ensuring that safety protocols are upheld throughout the life of the equipment.
