Main Vent Installed Off Plumb

Peter D

I just had my main vent installed with a #1 Groton on a 22 ft. 1.5 " main. The steam pro's worker who drilled the main and put the vent pipe on has it off plumb by at least a bubble on the level. My question is will this vent work since its not plumb? How can I tell if its working? I can't really feel any air coming out of it when the boiler is on. So, I did try this, I started the boiler and felt for steam from when the header got hot to when the vent got hot and clocked it at 8 minutes. But this time changes depending on how long ago and how many times the boiler fires. I don't want to pay for something that's not right, I just want it to work properly. So, how can I prove this vent is releasing air?
Thanks for any of your suggestions,
Pete

does he have the room

to swing joint the pipe so its plumb? you should be able to tell if its venting by using smoke from a smoke pen, match, cigarette etc and holding it by the hole..or cover the vent with a ballon..

Slightly off level shouldn't hurt it, but if it's off by the whole bubble that could be a problem.

Is that the only steam main in the system?
