When an excavated pit under a furnace cannot maintain proper clearance, the best course of action is to redesign the installation. This involves assessing the layout and configuration of the installation to ensure that it meets the necessary clearance requirements for safe and effective operation. Proper clearance is crucial for adequate airflow, access for maintenance, and compliance with safety and building codes.

Redesigning allows for adjustments in the size and location of the pit or possibly the choice of furnace type that fits the space requirements while adhering to safety standards. This approach not only rectifies the immediate issue but may also prevent potential problems related to heat accumulation, combustion air concerns, or safety hazards in the long run.

Other options may address symptoms, but redesigning the overall installation comprehensively tackles the clearance problem and ensures all applicable codes are respected.
