Question:

Help! Gas boiler refuses to shut off?

We have all our windows open 45F outside and it's 85 inside. A bathroom remodeling contractor was supposed to replace our hot water baseboard today with a towel warmer (Hudson Reed - it's gorgeous). Anyway, he called me today and said he felt uncomfortable draining the system since there was no shut off valve and he wanted to call in one of his HVAC guys. Then he later said he didn't want to leave us without heat for the weekend so they left it alone. I feel like some sort of override switch must have been thrown - the thermostat is not controlling the system. We set it down to 55F and it's still pumping out fire. I see some switches in the ceiling, but I don't know what they do. On looks like a dual push button (probably one or the other is always depressed). The other looks like a light switch and it is flipped to ON. I don't even want to think about what the gas bill for this is going to be, let alone what it could be doing to the boiler itself.

Answer:

Manually close the gas valve to the boiler. This will cut out the fire. Then get a qualified service technician to look at it later.
What is the best way to shut off the gas? I can flip the lever on the pipe to off, or use one of these switches I mentioned above??
turn off the gas to the boiler and then turn off the Circuit breaker that controls the boiler.... Make sure you turn the gas off FIRST......then the Circuit breaker....this will disable the entire system.....if the boiler is allowed to run wild it will damage the boilers firebox, ..
