end of main air vents and traps

Joe Jesse_2

I have a 400,000 BTU Weil McLain boiler in a 3 story building with 20 radiators with a 2 pipe system. Both of the main steam lines end with a radiator thermostatic trap followed by Gorton #2 vent before dropping down into the Hartford Loop. This is 4 years old and everything seems to work well. What would be my advantage in trading 2 F&T traps for the 2 radiator thermostatic traps?

Nothing. Leave it as it is, unless you're having some sort of problem.

If the steam is slow to distribute thru the mains, you need more venting, not different types of traps.
