When baffles are closed, what percentage of the chimney connector area can they block?

When baffles are closed in a chimney connector, they can block up to 80% of the area. This is significant because baffles are designed to promote efficient combustion by controlling the flow of gases and optimizing the draft within a system. If they can block such a large percentage of the connector area, it indicates that they play a critical role in maintaining the necessary conditions for proper venting and operation of heating appliances.

The function of the baffles is to create resistance that helps to slow down the exhaust gases, thereby increasing the time the gases stay within the heat exchanger or flue, allowing for more heat transfer before being vented outside. By blocking up to 80% of the connector area, they effectively ensure that the appliances operate efficiently and that harmful emissions are minimized.

Understanding this percentage is essential for compliance with safety regulations and enhances the operator's ability to diagnose potential issues related to airflow and combustion efficiency in oil-burning appliances. It helps ensure that the systems are functioning correctly and safely.
