balancing a one pipe steam system in a 25 unit co-op

There seems to be conflicting information regarding how one goes about choosing the vent size for radiators.....on one hand Dan says to size according to rad size and not location while Gortons instructions on their vents says to use smaller vents near the boiler with bigger vents for rads far away from boiler. Who is right?

vent sizing

I have found by using dan,s method has worked very well for myself but please remenber that your mains and riser need to be properly vented also in most commerical building that thermostaic raditor valves work very well to help avoid over heated rooms and apartmenmts they cost a little bit but you will see savings in your fuel comsumpition and the tenants won,t have there windows wide open because it's to hot .Peace and good luck clammy

A combination of both

I vent rads also according to what kind of temps the occupants want in those rooms. Mad Dog

thx guys

yes, I will make sure the main vents are operating as they should..still learning here but dans books are on order and hopefully that will clear up some issues.....but before the books come....one question. I have a good sized ceiling mounted kitchen rad that was not getting any heat at all....I changed the vent to a maid o mist number 4. The basement apt is very close to the boiler. It heats up very good now but concerned weather or not I should have a larger vent. I get fast rushing water vapor when the rad starts getting hot. It isn't dripping water but when I hold my hand over the vent, my hand gets wet. Any thoughts or recommendations?
Thanks
Chris
