Boiler stays on.


If you have a large steel tank, its probably water logged, and needs drained.
And, your auto feed make be bleeding water in.

A tank in the ceiling right? Yea I could hear water still flowing into the boiler, sound like it was coming from there?

I thought that's supposed to have water in it?

That tank should be 1/3 to 2/3 max full of water.

Had someone look at it tonight.
He said the gas valve might be sticking? He shut the gas flow off & said you're supposed to hear a click sound in a min or so? The click came in around 3mins so he suspects it might be sticking open hence the boiler not turning off when temp is reached at t stat?

If it over heats to 77 plus every cycle. You can shut the power off to the boiler when the house reaches temp. Then go look if you still see the burner on or not.
If it off, its not the valve, if it on, its the valve.

We had a problem with the flame was coming up the side (see where it's burned) because there was soot clogging that side & the pilot light is there also.
I tried all of the breakers trying to turn it off, nothing until the gas man turned off the gas to the boiler and then the off button on the gas valve.

Try taking 1 of the wires off the gas valve & see if it turns off. With t.stat off & it keeps burning mabe stuck valve, Bad t.stat. If you have a 24v test light commect it to the g.v. & turn t.stat off position. If the light lights up & boiler is on the t.stat is keeping power to the g.v.

check the boiler control there should be a high temp cut off in an aquastat. this may be malfunctioning the boiler should cut off when the high limit is reached. sticking zone valves and thermostats do not control or effect the high limit on a boiler. If you exceed the high limit for long your boiler could dry out and crack.

If thats a powerpile, then teh electric feed only operates the aquastat, and powers the sirc.
