Sizing Steam main air vents

Jeff_74

Have just read Dan's "We Got Steam" book and now know I need to replace my main vents. I have two mains on my one pipe steam system. One is 61 feet in length, the other is 44 feet. Both are two inch pipe. Any advise?
The mains are insulated.

I'd use

one Gorton #2 vent on the short main, and a combination of one Gorton #2 and one Gorton #1 on the longer one.

If you can't find Gortons in your area, try www.statesupply.com .

The #2 vent is not cheap, but will save you a lot of fuel.

They're both

about the same capacity, but the Hoffman usually costs a lot more. You would need four of these to equal one Gorton #2.
