Should manual dampers be installed in connectors for solid fuel-burning appliances?

Manual dampers should not be installed in connectors for solid fuel-burning appliances because it can create safety hazards and operational issues. Solid fuel appliances, like wood or coal stoves, require a consistent airflow for efficient and safe combustion. Installing manual dampers can restrict this airflow and lead to improper drafting, increasing the risk of smoke or potentially harmful gases backing up into the living space.

Furthermore, solid fuel appliances are designed to function without manual adjustments to airflow after installation, ensuring that the system operates efficiently. Automatic dampers might be permissible under certain conditions but typically do not involve manual intervention. This ensures the appliance can maintain the necessary combustion conditions without the added complication of manual adjustments.

In essence, avoiding the installation of manual dampers in such systems aligns with safety protocols and operational best practices.
