Hi. Our boiler ( Junkers , old) stopped working. I tried to reduce the temperature of hot water it provided, and turned the knob regulating the flame slightly down and the boiler went off. As I don't have an instruction and I can't find the user manual on the Internet, I can't fix it. I wonder if you could help me with the problem. Thank you
