What component is activated when the hot contacts close in a burner system?

In a burner system, when the hot contacts close, it typically activates the safety switch heater. This component plays a crucial role in ensuring that the burner is ready to operate safely. The activation of the safety switch heater is essential for pre-heating the safety switch, allowing it to ensure the system reaches a state where it can verify that safe operating conditions have been established.

This process enhances the reliability of the burner system by preventing unwanted ignition or burner operation under unsafe conditions.

While other components like temperature sensors, pressure regulators, and flame sensors play important roles in the overall functionality of a burner system, they respond to different triggers or conditions. The temperature sensor monitors the temperature and ensures it stays within safe limits; the pressure regulator maintains the correct gas pressure for combustion, and the flame sensor ensures that a flame is present during burner operation to prevent unsafe conditions. However, it is the safety switch heater that is specifically activated when the hot contacts close, making it a pivotal component of the burner system's safety protocol.
