Adding tees for more main venting

I plan on adding more venting to my 1 pipe steam system. Right now the main vent sits on the elbow of drop return. Due to concealed piping and finishe ceiling, my only feasible option is to add a 4" nipple on this port and run an elbow with a seriew of teees that will allow me to add more main line vents. My question is, instead of running the tees in the direction of the main, can I run it perpendicular to the main line.
The end result would be the tee connections will point back towards boiler as oppose to being parallel to main line.

Thanks.

That's what I eneded up doing

and it works fine. As long as the cross sectional area doesn't restrict the air flow, I don't think that it minds going around bends.

My vents are also on the elbow at the drop and that's supposed to be a no-no because of potential damage from condensate being accelerated into that elbow (and into the vents themselves by the fast-moving steam. I built up a series of nipples, elbows and tees and got my vents a good foot away from that elbow.

Thanks Steve. I will start my project now.

The direction the venting "antler" runs will not matter. The air will get out. Steve is right.

What is key is to minimize damage from a traveling slug of water. Make it work to get to the vents!

But the air?

Air does not care.

A tip I learned from Brad. Use a union to attach your "antler". Much easier that way as you can build the "antler" on your work bench and then attach it.

Thanks, Rod

Here is a more updated detail for you.

The bottom diagram, the "Antler Arrangement", is a fall-back position when one cannot readily cut in a proper tee set back from the end of the main.

It is "punting", I admit, but makes best use of the "crash tee" we see way too often.

The union also allows you to pivot the assembly for best fit in between your structure. I cannot vouch for any improvement in TV reception, however.
