protect main vents

Steve_168

How about this system you have drawn with 2 90's and a 12" nipple. Cut a hole in the ceiling and come up just above the ceiling into the joist space?

Any ideas on how to pipe these vent risers so that they don't get smashed. I am going to install Gorton #2 vents.

Short of

cutting in a proper tee, a "back antler" might work.

Keep the first riser nipple at least as high as it is, screw on an elbow then nipple-tee-nipple-tee (each tee for a separate vent if to be more than one), then a plug in the end of the last tee.

If the pressure is kept low enough and the steam dry, it should stand the test if time. I have this on several systems and no issues. Key is height, distance and if you can, more height.

Heres what I do,...

I use 2 elbow (90) fittings to make a swing joint then have a long (12 inch minimum) pipe leading to a 45 or another 2 elbow swing joint and point it heading back towards the main,.. I figure condensate wont want to make all those turns and go uphill to the vent.

I hope this quick sketch helps.

Edit: sorry fro the orientation, I stink at scanning and manipulating images. hopefully you get the idea

From the picture it looks as if you'd have enough space without going into the joist bay.

I generally like to avoid going above finished ceilings unless your going to cut a large enough hole that you can easily see the condition of the vent.

But sure that would work.


Using 2 90's on the main side and the vent side allows you to get whatever angle you need given the space you have available.

It's hard to tell form the pic but those vent are right up to the ceiling.
