🔍 Key Concepts

• Automatic combustion control systems on auxiliary boilers • How a flame detection (safety) device works in maintaining burner ignition • Difference between conditions that cause a shutdown vs. conditions that cause failure to re‑ignite

💭 Think About

• Ask yourself: which option directly affects the control systems ability to SENSE that a flame is present after ignition? • Which choices describe normal operating conditions (pressure, airflow, voltage) versus a component that could PREVENT the system from recognizing a successful light‑off? • In normal sequence, after a safe shutdown, what must happen (and be confirmed) before the burner is allowed to keep firing?

✅ Before You Answer

• Identify which item is specifically part of the flame safeguard / flame scanner circuit. • Eliminate options that are more likely to be a result of no firing rather than the cause of failed ignition recognition. • Verify which device, if malfunctioning, would cause the control to keep thinking there is no flame, even if the burner actually lights.
