To get the open area equivalent of a 2" vent pipe would only require the
bottom of the panel to be 1/2" above the top of the vent pipe. However,
for folks in a cold climate, condensation freezing into a large ice
block on the bottom of the panel could block the vent or damage the
panel. Pretty sure vent pipes under the array are not a good idea for
many of us.

Scot,
What do you interpret the last part of that section to mean? ‘The
placement of a panel over a vent pipe… shall provide for an open area
for the vent pipe to the outdoors that is not less than the area of
the pipe…’
Is that saying if you have 2” PVC you need your panel 2” above the top
of the pipe?
Thanks for bringing this up.

Complete game changer. I stumbled upon it in Fine Homebuilding article
and was surprised this was not more widely known. Vent pipes can be
reduced in height. Details in plumbing section.

I have relocated roof vents several times, just have to make sure
they comply, no P traps, flat or downward trends. Fasten correctly
to the rafters, sealing both old and new. If you want to do this
on the roof under the modules same rules apply.

Friends:
Over all these years I have always been able to work around
plumbing vents. Now I find one that is just in the way. My
foreman suggests we 90 it out of the way, and makes the point
that there are vent 90s in the walls all the time. Is there
any concern about this practice?
Thanks in advance.
