this high limit safety control ensures the system remains within safe operating parameters by interrupting the electrical circuit if the heat exchanger exceeds its factory-set thermal threshold

Optimized Performance: Facilitates rapid heat-up for efficient gas burner ignition and reduced startup lag

Contaminant Protection: Features a high-density internal filter to trap copper shavings and debris down to 25 microns

maintaining structural integrity and alignment even under constant hydraulic pressure

Always verify the resistance curve requirements of your controller to ensure it matches the 10k Pre standard rather than standard Type II or III curves

Lennox 95M53 Orifice mario this high limit safety controlTechnicians and contractors know that maintaining proper airflow is non negotiable for system longevity and efficiency.
