Pressuretrol settings
How long should a steam system "hold" pressure after the boiler cuts out at the high pressure limit? I did some testing at 1.5 psi (with a 0.5 psi low limit). Boiler cuts out at 1.5 psi, but pressure falls so quickly that the boiler fires again within 60-90 seconds. Doesn't seem like much of a fuel savings - I imagine something in the system isn't working as planned?

The quick rise means your boiler is oversized for the system it serves. The fact that the pressure falls quickly is a good indication that your system is well vented.
