    Thanks Bob! I will pass along this information. I also messaged harvey ramer on fb and asked him for the link to that article and he sent it to me.
    I'll post it here incase anyone else stumbles on this thread with the same issue:

    What's the cold pressure on the boiler? The gauge is underneath, on the bottom of the boiler.

    Bob, you mentioned boilers running at 150 degrees or less. what should ours be set to? i think it runs at 175 or 180. ill check the display after it heats up again... but i know its at least 175.

    That's gonna depend upon the type of radiation that you have and what SWT it was designed to operate at. The boiler has ODR which will vary the SWT based upon ODT.
