Excessive smoke detection triggers what response from the system?

When excessive smoke is detected by the system, it indicates that combustion is not occurring efficiently, which can lead to unsafe operating conditions or potential hazards such as soot buildup or even fire. To protect against these dangers, the system is designed to trigger a complete shutdown of the burner. This automatic safety response ensures that any underlying issues causing the excessive smoke, which could range from fuel supply problems to incomplete combustion, are addressed before further operation. By shutting down the burner, the system prevents further safety risks and facilitates troubleshooting to maintain safe and efficient operation in the future.
