I'm posting this a few days after seeing the actual burner. A friend of mine has a WM hot water boiler. I *think* its a WGO gold series boiler with a Beckett burner. Problem is I cannot remember what model burner it was other than it is NOT an AFG.
Burner seemed to run good but kept squeeling occasionally. the squeel had a very metallic sound to it. To me it sounded like a bearing issue but I know close to nothing about these burners. Is this a sign of a soon to come failure? Is there any preventitive maintaince that should be done?
