Steam Question

I flushed a LWCO and some water came out and then steam came out, the water level in the gauge glass is 4 to 5 inches above the arrow on the M/M #67 when this happened.There is a check valve on the return, hartford loop has close nipple, and water hammer after startup, pressuretrol set at 1/2 lb.
Does any one have any idear whats causing the steam to come out of the LWCO?
Thanks Mike
