Vent Rite #31

Does anyone know what the venting capacity is for a Vent Rite #31?
I cannot find this vent in the capacity chart nor anywhere on the web.
Thanks
Dave

Is this

a radiator vent, or main vent?

That's one I'm not familiar with

but it is likely too small for the job. If this is a one-pipe system, measure the length and diameter of the steam mains and dry returns and we can tell you what you need.

If this is a Vapor system, how many radiators discharge into the dry return where the vent is?

Thanks Steamhead,
No - this isn't a vapor system - just another knuckhead job.
Last year you suggested Hoffman #4 on each of my mains.
I will remove this vent once I install the main vents.
Thanks again.
Dave
