Vent sizes
I'd put two Gorton #1 or Hoffman #75 vents on the short main, and a Gorton #2 on the long one. The Hoffman #4A is too small for either one.
You want to fill the mains completely with steam in about a minute. These vents will do that.
The Gorton #2 is the largest vent made today. If you can't find this vent in your area, go to
www.gorton-valves.com
or call Gorton at 908-276-1323. Talk to Ken Kunz and tell him I sent you.
