• A. Heat Hole
• B. Cold Cut
• C. Break Hole
• D. Overhang

Answer: (A)

Opening a ventilation hole directly over the seat of the fire is called a heat hole. The seat is where the fire’s intensity is greatest, so venting straight above it provides a rapid path for the hottest gases and heat to escape. This helps purge the thermal layer and reduces heat buildup in the space, which is why this opening is termed a heat hole. The other terms don’t fit: cold cut isn’t standard for a hole directly over the fire, break hole isn’t a common ventilation term, and overhang refers to a structural feature rather than a ventilation opening.
