- Today we are taking a quick look at the basic operations of a flame safeguard. The flame safeguard is the primary boiler control that serves as the brains of the whole operation. This boiler control supervises the flame and prevents over-pressurizations. It is also a critical component for troubleshooting a boiler that won't start. Understanding the sequence of a burner's control helps to identify causes easier when troubleshooting a flame failure or boiler that won't start.
Some of the questions that we aim to cover in this video are:
What is the FSG of a Boiler?
What are the most common boiler controls?
What is the sequence of a burner?
What does MTFI mean?
What does PTFI mean?
What is a call for heat on a burner?
How does the burner know when to cut on and cut off?
What is a purge and pre-purge on a boiler?
What is a purge timer?

Also, the RUN/TEST switch at the top of the controls to lock the FSG in its current position. Good for troubleshooting.
Absolutely!
Just subscribed to your channel. Great information. Keep them coming!
I worked with the guy who designed the newer nexus systems, he just retired this year though but it was cool to learn from the horses mouth lol
Amazing technology
Good information!
Thanks!
What’s it mean when the FSG ALARM red light is on?
Good info
Glad you think so!
Hello! We have a blue box, Honeywell burner control, but it doesn't light up - as if it's not getting power. Can I replace the whole burner control? Is that an easy install? I have it already taken off - just two screws hold it in. Have you done a video on that? Thanks!
Feel free to give us a call with any questions. Before you part with the controller you should use a meter to verify power is still coming in to the programmer. www.powermechanical.com/
