What levels should chimneys with multiple openings have?

• A. Only one level
• B. Different levels
• C. All at the same level
• D. Lowest level only

Answer: (B)

Chimneys with multiple openings should have different levels for effective operation and safety. This design allows each flue to function independently, reducing the risk of cross-contamination of flue gases. When the openings are at different heights, it ensures that the combustion gases can safely rise and vent outside without interfering with one another. This configuration also helps in maintaining adequate draft conditions for each appliance connected to the chimney, which is crucial for efficient exhaust and preventing backdrafts. Therefore, having multiple openings at different levels enhances the overall functionality and safety of the chimney system.
