How do I adjust the outlet pressure once the spring is installed

This genuine OEM part is engineered to monitor the burner's pilot or main flame

By preventing "cold starts" and reducing the risk of catastrophic compressor failure due to liquid slugging

but the base rails or specific Lennox mounting frames must be retained from the original unit

Sporlan 953580 Interface Board 318518-761 Direct Coupled Design: Streamlines installationThe Sporlan 953580 Interface Board, also known as the IB G Control Board, is the advanced technical successor for the discontinued Sporlan 952956. Developed for precision refrigerant flow management, this HVAC interface module converts 0 10VDC or 4 20mA analog input signals into digital step motor pulses to drive electronic expansion valves. As an all in one replacement, the 953580 consolidates the functionality of previous IB 1, IB 2, IB 3, and IB 6
