How do I adjust this Honeywell Pressuretrol?

ww Member Posts: 268
Here are a couple of photos of what I have. American Arco Boiler with Beckett AF.

It seemed the radiators heated up fast when I had the 1.10 gph ss nozzle. I replaced with 1.10 80 degree hollow and it takes a long time. I am working with Main Vents now and moving them around. Would that nozzle change make a big difference in heating up the boiler?

    I'd need a close-up of the Pressuretrol before I could guess how you'd adjust it. They don't make them like that anymore, and I'm not sure if its cut-out or cut-in is directly adjustable. They've always come in two flavors.

    Do you know if the thing works? Is the boiler cycling on pressure? If you've downfired a boiler, the cycles are going to be longer. Considering its age and the absence of a steam trap to isolate it from live steam, it might not be working anymore, and there's no adjustment for broken.
