: Does anyone know how I might get the operating instructions or manual on the above Gas Boiler. It is pretty old but still going strong. I occasionally have to fix minor problems as well as do the seasonal maintenance. But I would really like to know more about this system.
: It recently shut down for no reason and I simply flipped an off/on switch to the On position and now it's working again. But I don't know what that switch exactly does. This switch is located in a small box with a skinny copper tube coming out of the bottom and leads next to the pilot light (a wire also leads to the gas valve form this box). I'm assuming it's (the copper tube thing) a thermocouple? Why did it shut down? Thanking anyone in advance for any info.
