Just noticed in the original post, something frankly, alarming.
60 pounds of pressure?
Should have released through a pressure relief valve at 30 pounds. My contractor put two on, as he'd had one fail and the boiler a "Tarm" looked like it was pregnant and was definitely ruined. 260 degrees at 60 pounds is high pressure steam... the kind of stuff that kills people, even aware ones. Definitely want to get that checked.
My WC90 is connected with 1 and 1/4 inch steel, with a circulator on the return, expansion tank and check valve in the supply.
Aquastat starts circulator at 140 degrees. Fan comes on with power switch, shuts off at 175 degrees, and off again at 160 degrees.
Overheat zone is set at 190 degrees, allowing boiler to hover in 175 to 190 degree range without any action.
Automag valve is connected to main zone in house, to allow gravity feed in a power failure.
Must be a heck of a draft in your chimney...
Lighting process is simple, really.
Roll some newspaper up, and throw it in the firebox. Put some kindling wood on top of it. Light the newspaper on fire and close the door. Turn on the power switch and pull up a chair. Fire! Lots of fire!
Let it burn down to near coals, to red hot coals. I usually add some more wood and bring the boiler up to temperature to start the circulator, and allow the second load of small wood to burn down to coals.
Turn off the switch, so the blower stops. Add a couple inch thick layer of coal. Close the door, and turn it back on. Let the coal "light". Some red pieces around the entire area and blue fire over the whole thing... turn off the switch and open the door, put more coal on...
even layers of coal, up to the bottom of the door, then a little pile in the middle, toward the back of the boiler.
The idea is to not open the door and have burning coal spill out in your lap... otherwise, knock yourself out.
No idea why the blower would be causing such a disturbance you'd need to disconnect it and take it off. It has a shutter on it, you can close that...
