vents on steam condensate line

Ahh, so the steam extends thru and past the radiators to a common vent? How would you balance that bad boy?

#75 Vent on condensate return

I increased the number of vents my main steam return from 2 #75 hoffman to 4. I currently have 1 #75 hoffman on the condenste return. Would it help increasing the venting on the condensate side?

Tough to say

without knowing more about the system. Do you have this?

Balancing steam systems

I don't have this book I will look into getting it. The main loop I believe is 3" and about 75 ft. It had 1 #75 on it on the main return and another on the condensate return. Last year I posted a question about main vents. Steamhead recommended either a Gorton #2 or 4 #75's. I made a manifold of 4 #75's. It works well. Steamhead had also mentioned that if you can hear the vents then you do not have enough venting capacity. Is this true on the condensate return?

A question. What are you venting on a condensate line? The vents are to let air out so the steam can get in. The condensate runs like a drain pipe and will drain reguardless of pressure vacume or whatever, as long as it pitches down hill toward the boiler. Why the vent?

Brian, that's

a 2-pipe system with traps on the radiators, correct? How much radiation do you have?

For 700 square feet EDR

in a 2-pipe system with no vents on the rads, start with two Gorton #2 vents on the dry return.
