There is some type of loop in the return line but it is higher than the pictures I have seen that should the loop coming into the main header 2inches below the water line. My return line comes out of the bottom of the boiler and goes up, it mades a 90 turn about 1.5ft from the ceiling. It then goes straight and before it connects to the main steam line there is a loop. The loop is below the main steam line. The vent in question is just after the 90.
I cannot see the pictures on the web site..I must be missing some software.
