All you should need to do is turn the valve back on that you shut off when you drained the system. Do not run the circulators with no water in the system.

You may have a problem with the feed valve they look something like this.

Is this a regulator valve set for 30 PSI?

It is located off the feed line to the boiler.

Is this the valve you are talking about?

Expert:  Rick replied 7 years ago.
The feed valve (regulator) is factory set to 12- 15 psi not 30 psi. At 30 psi the safety valve will pop. Yes this valve is located on the water supply line to the boiler. Under normal conditions the valve will let water into the system slowly and stop at 12-15 psi. Most have a lever that you can move to fast fill the system. The one in the pic is sticking out of the side. If you have a bronze colored one it will be on top. You flip this lever (on a watts valve the bronze one) straight up to fast fill but watch the pressure so it doesn't get too high (15 psi max cold). You also flip up this lever to boost the flow when you are purging the system of air.
