Using a life-safety actuator for standard modulation can lead to premature wear and code violations

Manual override lever allows for system flushing or emergency operation on normally closed models

allowing for tool-free attachment or removal from the valve body without breaking the hydronic seal

this is a 115v specific motor

How do I wire this into my existing energy management system

Reznor 62594 Ring 321894-706 Using a life-safety actuator forThe Reznor 62594 Inlet Venter Ring is a critical OEM replacement part engineered specifically for gas fired unit heaters and precision industrial heating systems. Designed to sit at the air intake interface of the venter motor, this venter ring serves as the primary seal to prevent air bypass and ensure optimal combustion airflow. By maintaining a pressurized air path, it stabilizes the induction process, allowing for consistent fuel to air ratios and
