Precise Calibration: The #42 drill size provides the exact flow rate required for LP gas configurations in Johnson Controls HVAC parts
the stem extension should be threaded to a gauge height of 2-1/8 inches (54 mm)
This pilot safety sensor is engineered to generate the necessary voltage to hold the gas valve solenoid open under standard operating temperatures
ensuring the valve stem remains securely sealed without increasing mechanical friction that could lead to actuator hysteresis
Key Benefits: Factory OEM replacement ensures correct temperature calibration and terminal orientation for York
Lennox 57M67 Pressure Switch Precise Calibration: The #42 drillThe Lennox 57M67 Pressure Switch is a high precision OEM component engineered for critical safety monitoring in gas fired furnaces and HVAC systems. As a veteran technician knows, maintaining the correct pressure threshold is vital for inducer motor verification and combustion safety. This SPST pressure switch is factory calibrated to actuate at 1. 71" WC (water column), ensuring that the exhaust blower is moving sufficient air before the ignition
