It sounds like a simple thing to shut down a boiler...but we are baffled and can't figure out how to turn the beast off. We found out it is a system that turns on based on outdoor temps and since the sensor hasn't been reset is who knows how many decades every morning it ramps up and starts heating up in preparation for a day of heating just to shut down again as the day warms up. Our HVAc guy said it would need to be set each new eating season and it would be pricey. We plan to completely remove the boiler and it's whole system of water pipes any how, so we want to go ahead and stop our ridiculous gas usage now. We can't just shut off the gas since out hot water heater also used the supply. Any ideas?
you have to have a shut off at the boiler for the GAS...tape the wires away from the main gas valve...shut the emergency switch down or the toggle next to the boiler to kill the 115Vs and intern the 24Vs control....pull the stat off the wall and cut the W and R wires off the subbase...shut the water make up and drain that sucker down...put the main GAS valve within the furnace to the off position!
