What happens when you turn off the boiler sight glass?
When I turned on the system, the boiler started up OK, but the then the water in the sight glass eventually went down to the cutoff level, shutting off the boiler. Then it returned to a level allwing the boiler to come back on and kept recycling like this.
What to do when your boiler needs to be shut down?
Inspect low-water fuel cutoff control for proper sequence and operation. Verify that it shuts off the fuel supply to the boiler as required. If necessary, replace the glass even if the boiler must be shut down to do so. It’s also crucial to perform periodic maintenance of the piping leading to the glass gauge.
Why does my boiler turn off every few minutes?
It does not take the heat exchanger long to reheat this small amount of water back to the thermostat’s temperature setting which is why the boiler quickly turns off again. If the boiler fires up every few minutes it is using gas but not heating your home.

Why does water run out of boiler stem?
The sightglass valves should both be open. Take the bottom valve out and water should run out the stem if the water level is at least minimal. If you flush your low water cut off and water comes out nicely and the boiler stops if running this is good, it’s just a block in the gauge glass connecting pipe.
