Main vent location

Steaming101

I have two mains runs one is 19ft and the other one 11ft. I've been reading abt vent ratings and locations but I'm a little confused abt the locations. R this located correctly!

The first one with the gorton #2 looks correct. The other one I'm not sure. what do the 2 horizontal pipes lead to? It looks like a location for a vent but if one of those mains leads to more radiators you'll need a vent where it drops down into a return.

The main with the Gorton # 1, it's 11ft main coming from left side and it goes to a radiator in 1st floor. The return it's the pipe under the vent.

Do both main vents get hot about the same time?

No the 11ft main its abt a mnt slower so I'm going to add a gorton # 1 to that side.
