Frozen Pipe help!


Got home today, one of my zones didn't turn on (I preset zones to turn on an hour and a half before I arrive home). I remember a year ago I had the same problem with this same zone. My oil heat company sent out a technician. Reading my invoice from last time, this is what it said:

"Heating zone frozen, raise pressure in boiler and open flow check to defrost zone"

I remember it didn't fix the problem at that time, but an hour or two later it seems to fix itself. I think I had to have the guy come back to turn off the flow check or something. That trip costs me $100. My question is, can I do this myself?

I have attached the flow control valve and the motor picture (each end of the zone). My questions:
1: How can I open the flow check myself? I'm afraid that the motor will burn out as it has been on for an hour and a half and cannot push the hot water through.
2: Which way is the hot water flowing? Is it coming out of the motor side or the control valve side?

I really appreciate any expedited response...tomorrow it will be 37 degrees in Massachusetts, but making it through tonight is what I'm worried about. The pipes are as you see in the picture.

Thank you so much in advance!

Frozen Pipe help!


Water flows into the bottom of the flow check and out the other pipe. Turn the knob at the top counter clock wise.

Thanks beenthere. Unfortunately to alleviate my fears, I called the plumber. I knew temperatures would get to 38 for a few hours but I didn't want to risk it. 2 minutes before plumber arrived at my doorstep, I found that the zone started heating up...it must've cleared itself. Yes, I didn't make that up...2 minutes. $300 gone. Bad luck
