Pardon my ignorance, I don't know the technical language here. I've noticed more light coming from under my boiler by the access door to the burner section. When I opened it this s evening the flames are coming up the side of the burner. I have video but was not able to upload it so I screenshot the video for you to see. I'm pretty sure this isn't right? Any ideas on what I need to do to remedy this? I am a 2-pipe steam system. thank you.
