Automatic dampers for oil-fired heating appliances must comply with which standard?

Automatic dampers for oil-fired heating appliances must comply with UL 17. This standard is specifically related to the safety and performance of automatic dampers used in conjunction with heating appliances, ensuring that they operate effectively to control airflow and prevent the backdraft of combustion gases.

Compliance with UL 17 helps ensure that these dampers are designed to respond appropriately under various conditions, which is crucial for the safe operation of oil-fired heating systems. Automatic dampers play a significant role in maintaining efficiency and safety by regulating the flow of air in the appliance, allowing for better combustion control and reducing the risk of hazardous situations.

The standards listed in the other choices do not pertain to oil-fired heating appliances. Understanding the specific standards applicable to different equipment ensures that installations are compliant, safe, and efficient. In this case, UL 17 is key for automatic dampers, which underscores the importance of using the correct standard for specific types of heating appliances.
