What material should the cleanouts for chimneys be made from?

The cleanouts for chimneys should be made from non-combustible materials to ensure safety and compliance with building codes. Non-combustible materials, such as certain metals or masonry, are essential in preventing the risk of fire hazards associated with the high temperatures generated in chimney systems. By using non-combustible materials, the structural integrity and safety of the chimney system are maintained, reducing the likelihood of ignition of nearby combustible materials.

Other materials like ferrous metal could potentially rust or deteriorate over time when exposed to the elements, affecting their effectiveness and safety. Wood is inherently combustible and poses a significant fire risk, making it unsuitable for cleanouts in chimneys. Plastic, while resistant to certain chemical exposures, also does not possess the necessary fire-resistant properties needed for a chimney cleanout. Therefore, only non-combustible materials should be used to ensure the safety and effectiveness of chimney cleanouts.
