Where must the inlet to a masonry chimney enter from?

The inlet to a masonry chimney must enter from the side in order to ensure proper airflow and efficient draft. When the flue or inlet is positioned on the side, it promotes a more effective transfer of combustion gases while minimizing the risk of blockages and backdrafts. This design allows for optimal alignment with the natural flow of the gases that need to be vented outside, contributing to the safety and performance of the chimney system.

Positioning the inlet on the side also helps to prevent condensation from forming within the chimney, as it allows for better temperature control and ventilation. If the inlet were located at the top, bottom, or front, it could lead to inefficiencies in the system, including poor draft and potential safety hazards due to the accumulation of combustibles or exhaust gases. Therefore, the proper placement of the inlet on the side is crucial for the effective operation of masonry chimneys.
