What is the recommended height for cleanout openings according to NFPA 211?

The recommended height for cleanout openings according to NFPA 211 is set at 16 inches above floor level. This height is established to ensure ease of access for maintenance and cleaning, which is crucial for safety and efficiency in chimney and venting systems. Having the cleanout at this specified height allows for comfortable operation while minimizing bending or awkward positioning, thereby promoting regular inspection and service. This guideline contributes to maintaining optimal airflow and reducing the risk of blockages or hazardous conditions in the flue system. By adhering to this standard, practitioners help ensure the longevity and reliability of the fireplace or chimney system, emphasizing safety and compliance with recognized construction practices.
