You might just have a pressure guage mounted on the front of your blr. One pound per square inch = 27" of water in height so you need about 14psi on the guage. The prv might look like a flying suacer. It is probably the only thing you have in that line from your drinking water to the blr. There may be a handle on it to "rapid fill" it. You leave the drain alone except once a month blow about a half-gallon of water out into a bucket to get rid of solids. Try bleeding just the bottom radiator a little at a time until you get the air out and work your way up. The water up above will help push air and keep air from going laterally if you have series piping. You should get a boiler owner's manual off the internet for a similar blr.
