I just had a cracked boiler replaced. I read a lot on this forum and I'm looking for feedback on the final installation. It takes about 18 minutes from a completely cold start for steam to reach the main vents. The timing on both returns is nearly identical. By that time all the radiators are warming up. All the vents have been replaced. Big mouth mains and Gortons on all the radiators. The system won't shut off on pressure and will run until the thermostat is satisfied. I can't even read any pressure on my 5 PSI gauge which I guess is a good thing. How does everything look? Did I miss anything? (Except for the fact that a vaporstat would be better than a pressuretrol, but everything is working so I may or may not address that in the future).
