This part is the designated updated version for the 033199-0539 and fits the same 3/8" ODF piping specifications for a direct drop-in replacement

This specific low ambient control typically utilizes a temperature sensor mounted on the condenser coil or liquid line to sense head pressure indirectly via temperature saturation

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

Maintaining the integrity of the flue temp sensor interface is vital for preventing overheating and ensuring the control board receives precise data for optimal fuel-to-air ratios

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

Reznor 62594 Ring 321894-706 This part is the designatedThe 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
