ensuring that exhaust gases are safely vented before the ignition sequence begins

Extreme Durability: Forged from black iron to resist corrosion and handle high-pressure fluctuations in commercial steam loops

By providing precise feedback to the system controller

If the switch is reset but shows an open circuit (no continuity)

the Resideo 32001615-001 is designed for a mechanical fit

Rheem-Ruud 47-21900-13 Limit Switch ensuring that exhaust gases areThe Rheem Ruud 47 21900 13 Limit Switch is a critical safety component designed for precise thermal regulation in high efficiency furnace applications. This fixed temperature limit control features a 150 degree Fahrenheit open temperature set point, making it essential for preventing heat exchanger overheating. Engineered as a manual reset limit switch with an SPST normally closed circuit configuration, this part ensures the burner circuit opens
