Go here: https://www.google.com/search?sourc.....0..0j0i10j0i22i30j33i160j33i299.QoO6-EAxDr4

In the results look for the link to: [pdf] Panel Penetrations Product Technical Bulletin - MBCI

This will then download a .pdf. This will show you MBCI's standard details for pipe penetrations. MBCI (metal building components, inc) is a leading supplier of metal building components and is well respected in the industry.

Depends on the roof .. do you know the maker or is it standing seam?

It also depends on the efficiency -- an atmospheric will require a larger pipe w hotter exhaust.


This is the proper way to do a true standing seam vent -- the left is plumbing ..right is power vent boiler exhaust.
