Hot Surface Ignition Systems Requirements and Safety Features

What are some key safety features required for Hot Surface Ignition systems?

1. Hot Surface Ignition systems must have a flame sensor. True or false?

Answer:

True

Hot Surface Ignition (HSI) systems are required to have a flame sensor. The role of the flame sensor is crucial for verifying ignition and ensuring the presence of the flame for safety reasons.

This safety feature helps prevent dangerous gas buildups and potential risks of explosion or carbon monoxide poisoning.

The flame sensor detects whether ignition has successfully occurred and continuously monitors the flame's presence. If the sensor does not detect a flame, it will shut down the system to prevent any hazards.

This requirement highlights the importance of safety measures in modern heating systems utilizing HSI technology.
