they must point upward..but the branch or tree is okay..just so long as the vents point upward on the branch.

    Steam Vent Details

    Hello, my space is very tight to install new main vents. I have two #1 Gorton's on the way to replace a very old #77 Vent Rite. I haven't seen the size of the #1's as yet, so I don't know for sure how high [tall] they are.
    Is it okay to build a branch that is 90 degrees from straight up? I could come out of the existing bushing with a close nipple and a 90 degree elbow and build the branch from there. I would end up with the new vents "laying flat" as opposed to "standing up".
    Is this an acceptable main vent position?
    Thanks for any guidance.
    Mike

    Not Flat

    Thanks for the replies. So I can't have the vents laying flat even with the vent hole facing up. I guess my attempt to reinvent the wheel has failed.
    Thanks for the input and I'll have to think of a more conventional route.

    It is possible

    to drill and tap 1/2" pipe thread into the side of the pipe or fitting, and elbow up from there. This might give you more headroom.

    Detail

    Here is a detail I worked up for a short-staffed Menorah (Chanukah in a Churry!tm) which you may fine helpful. It is not really to scale. The Gorton #1's are about 2 inches across by memory only.

    Brad, thanks for the drawing. Man do I wish I had that kind of room to work with. I have very little height.
    I have two inch pipe coming along a foundation wall top, ending with a 2" 90 deg. elbow, into which is screwed a bushing with a 3/4 pipe thread in it.
    There is only 4 1/2" from the bushing top to the floor boards above.
    I can put a #1 Gorton there, but I'll have to check into Steamhead's idea of drilling and tapping a hole in the side of the pipe and going up from there.
    A big thank you to everyone who was kind enough to read and comment or make suggestions concerning this problem.
    I had hoped to be adding main vents at will, but it is never that easy.

    Well, to be fair..

    that detail went up between joists...

    I am hoping that a Gorton #1 does it for you. One of those will vent 100 feet of 2-inch pipe in about 3:20 (minutes/seconds) at 3 ounces pressure. If your main is shorter, (less volume) all the better.

    Detail

    Hi Brad,
    Sorry that I inadvertantly conveyed the wrong message about having the room for the drawing layout. I know full well that that beautiful branch had to be installed in some God awful inacessable knuckle busting place. Sorry I didn't actually say that.
    I only meant having 7 or 8 inches in height to work with would be wonderful for me and perhaps allow me to do what I had intended.
    Now I'll revert to that old addage that goes something like "if you find yourself in a hole, stop digging".
    I do believe that I'll be okay since I now have the capacity information that you provided.
    My 2" main pipe is only 28 feet long, so much shorter than the 100 feet the #1 will handle.
    As for the pressure, I don't know where I am. The pressuretrol diff. is 2 and the main is 3. the internal syphon PSI is 2.
    Brad, you have been very helpful and I can't thank you enough.
    Mike

    Oh, I was not offended, Mike. Not in the least..

    Far from it. By saying, "to be fair" only meant that I had room to work that you did not; that my suggestion was not being fair to your own situation.

    I was just acknowledging that your situation did not have that height advantage therefore my suggestion would not apply. Really, never took it as 'the wrong way!'. Kind of hard for me to do that....

    With the 28 feet of main, the Gorton #1 will do that in under a minute at 3 ounces. If you are running higher it will be a little bit faster but your steam is smaller so crank it down :)

    Good stuff!

    Brad

    Brad, thank you for everything. I'll go about getting that pressure lowered.
    Have a great day!!!

    Similar problem

    Hey, I think I am in a similar situation to you in terms of no extra space above my main - I think I only have 3 or 4 inches. The schematic below shows how the previous owners of my house dealt with it - they branched off of the vertical line that heads down to the wet return. I know this is not ideal, but I wonder if will do the job. I am having some strange venting from my rads that I am trying to troubleshoot...

    Gorton #1 or #2

    I spoke with Ken at Gorton today and maybe misunderstood. (He's sending the spec sheet via mail.) He's recommended #2's for each of my ~50 foot 2" branches. #1's are way smaller and cheaper. However, #2's vent faster. How fast is fast enough?

    No Space

    Jody, I am only learning myself. I believe that you have a two pipe system. Mine is only one pipe.
    I would suggest that you post a new thread and provide as much detail as you are able to supply. People are willing to help, but they do need to know what you have system wise.
    I think your information is now lost where folks won't see it. If it was in a new post, it would be seen by many more people.
    Perhaps your previous owner or dead man was creative and has an acceptable vent arrangement worked out. I wouldn't know.
    Those Gorton #2 vents will vent a huge main. I think I am safe saying that.
    Give it a try with a new thread!!!

    How fast?

    Jay, if you have already spoken with Ken at Gorton,[who is highly regarded in the industry] and you gave him the correct info that he needs, then you have your answer.
    I would suggest that you impliment what Ken said if you can possibly do it. The much larger #2 is an issue for those of us with space issues. So we have to do a work around. If you can't do the #2's ask Ken about building a branch.
    Sorry I can't be of more assistance, but your indeed fortunate that you found this site so you can get good information.

    3:1

    It takes about three Gorton #1's to equal the venting capacity of a Gorton #2. Actually the #2's are a little better than 3:1 but close enough.

    Vent too fast/big?

    I do have the room to use a #2 on each of my main branches which are 2" diameter about 50 feet long. How long will it take to vent these at 1/2 PSI? Is there such thing as venting too fast?

    Jody, that should work fine

    as long as water doesn't back up into the vent.

    Great!

    There is about a 5' drop to the wet return, so water should not be a problem.

    Good to hear that it will work, since I'm not sure what else I could do. Unfortunately, I am still having several of my rads vent loudly at times, so I've still got some trouble shooting to do. I just added the 2 #2 vents (my main line splits) and several gorton and hoffman rad valves, but I'm still having venting issues.
