Broomell reciever leaking steam

We have a Broomell system that suddenly started leaking steam out of top of the reciever through the valve that comes from the stean header.  How do you get it to stop?      Mike

What pressure are you running?

That receiver has a safety valve in it that opens at something like 7 ounces of pressure. This system should have a Vaporstat instead of a Pressuretrol to control the boiler pressure. Maybe the pigtail under the Vaporstat is plugged?
