Condensate return vents spewing.

Big WillBig Will Posts: 394Member
Here is a link to the pics of the system. https://app.companycam.com/galleries/gF6h7HxZ We pulled all the wet return piping so we could clean it or replace it where we could not clean it really well. The fun part is this never happens when we are on site. The house is all baseboard convectors. Any thoughts?

    Only thing that comes to me is that your operating pressure is so high that it pushes the return condensate column up that vertical pipe and out the vent as the natural place of egress. How high is your pressure? The pics show 2 psi with 2 psi cut out. That's waaaay to high! That will lift water up 9 feet. Is that vent 9 feet above the water line? If not, dial down the op pressure.

    Agree with above check the pressure. If this is 2 pipe you want it down in ounces of pressure.

    Also your Hartford loop nipple is supposed to be a close nipple not that long one you have in there. Not part of your current problem, but it can cause other problems.

    That's a big boiler to only have one riser out of it. Is there even a Header or does that riser connect right into the main(s)? Pressure and velocity of steam out of that boiler are both suspect.

    Pressure is supposed to be set for .5 to 2 psi operating range. It can certainly be lowered even more.

    the nipple into the hartford loop is to long, need a close nipple there and there are no pics of the header, love the peerless steamers, huge fan!!!!

    I am going to take an educated guess that there is no boiler header. Which means you're throwing a lot of moisture up into the system along with the steam. Which would certainly contribute to your problem.
