Main Venting Location

drfosters

Hi all,
New homeowner with a 1 pipe steam system. I'm pretty handy and been trying to optimize the system... Starting with venting the main whith I believe was plugged. I removed the plug on the top of the down pipe for the wet return and put on a Gorton #1 to start with (pictures attached). I don't have much space but trying to figure out if an antler with a 45° off the 3/4 port is my best bet (I have to kind of divert it a bit because it's under the joist currently. The main turns and drops down a couple of inches with elbows and then is the down pipe for the wet return. The pictures may explain this better. What are your thoughts. 

Thank you so much.

Try the gorton for awhile on its own. They can vent a lot more than people think.
