External Inspection of Furnace Fireboxes

Inspect the arch or roof tile and the tile hangers and supports. The hangers usually fail under the insulation covering the arch. Check for faulty soft insulation covering the arch. Large cracks or missing insulation allows gases to escape to the atmosphere. Inspect all exposed red brick surfaces in the outer walls for bulges or cracks where gases could escape.
