Why must the entire length of the chimney connector be accessible?

The entire length of the chimney connector must be accessible primarily for inspection, cleaning, and replacement. This accessibility is crucial to ensure that the chimney connector functions properly and safely. Regular inspection helps to identify any blockages, creosote buildup, or deterioration, which can lead to dangerous situations such as chimney fires or carbon monoxide leaks.

Cleaning is necessary to remove any buildup that can obstruct the flow of exhaust gases, and, if any parts of the connector are damaged or fail, they must be easily replaceable to maintain the overall integrity of the heating system. Therefore, ensuring the chimney connector is accessible aids in proper maintenance practices, contributing to the safety and efficiency of the heating system.
