Building Antler Setup for Gorton #2's

MikeBlue

Need to build antlers to run 4 Gorton #2's on the mains. What would be the best pipe and fitting material and is there an ideal distance between the valves? Any suggestions greatly appreciated.

make sure to use 1" for at least the first 2 vents off the main. Make sure the vents are spaced enough to turn them off one at a time or use unions if room is tight.

Here is a drawing

Just to be clear,

when I drew that drawing, I should have stipulated that the "Antler" arrangement is really "Second Best", the ideal being a proper tee held back from the main end.



The Antler at least is for when you "admit defeat".

I have a question about moisture...

On my antler setup, I can't go very high from the return. The ceiling is really close...and I notice a good amount of moisture getting to my main vents. If I were do do something like a "mini-drop header" on the antler, would that alleviate the issue? It's not really a big problem...but just curious.



I believe the moisture is there because it's at the very end where the wet return drops to the boiler.

No Drops!

Any drop on the way to a vent will fill with water, be a trap seal and defeat the purpose. The air vents need a path of air only.

If there is that kind of moisture, it all starts at the boiler. If such is the case and pending your correcting that, I would move the antler (or widen the Menorah arms), further away to give the moisture more distance to travel. Just allow it to flow back to the main.

Drops??!!

Hi Brad - thanks for your post...sorry to hijack...



Below is a picture of my Mouat vent...closer vent is the return, farther away vent is the supply.  I am thinking of replacing these Hoffman vents with Gorton.  If I understand what you said, these vents are not optimally placed because of the drop...correct?  How would you re-pipe these vents to be optimal?  I don't have a ton of room above the mains...



Thanks, and sorry to Mike for the slight thread hijack...

Those drops do not

concern me so much because any condensate can still fall freely below, assuming that the condensate never backs up above the side tee connection.



The drop I was referring to would be if you came off the top, dropped down to recover height, then rose again to the vent. That would create a "U" trap.



What you show is not ideal but could be improved by extending the piping laterally some distance, to a clear area where your vents can breathe more freely.  So yes, recover height but think how air and water would react on the way. Pitch up to the vent always.



The rust stains above though, say that the vents are in a danger zone or have failed previously. But if they work, do not fix them.



My $0.02 anyway!

Main Vent Clearance idea

Just thought I'd mention this as it might be of help. A couple of years ago I saw a neat solution to getting vent height with a finished basement ceiling. The owner used an electrical "can" like the type you use for retrofitting recessed lighting in the a dry wall ceiling. He stripped the electrical fittings and taped over the holes and painting it to match the ceiling.

The vent went nicely up inside and was attached using a pipe union.
