They're two seperate devices he's talking about. The long liquid expansion device at the top isnt there to detect a flame, its there to modulate temperature! The bottom device on the burner is the FSD, there to sense the flame.
I am wondering if there is anyone out there who can help me? Are gas engines required to provide a gas service check to a home with a disconnected gas supply?
Hi there I have just failed the ACS practice test, then I found your video and what to see whether you have got more videos for different rigs please Thanks Sam
