Jamie,
I don't understand your question.
Will the frying pans be left in the system or is this temporary when the
system is being worked on?

I have a ongoing project where we are separating by floor, an old bird cage
system from 1901. There are flanges on the top and bottom of each vertical
feed, unfortunately, each of these flanges is an older bolt pattern, (6
bolt instead of 8 bolt for 6" pipe), so cutting it out and installing a
blind flange is a no go. Years ago when working on these types of systems,
we used to use a "Frying Pan" or piece of plate steel with a handle slid
between the flange with a new gasket to separate the floors. Before having
some fabricated, I wanted to check a see if this is still an acceptable
method for system subdivision. I don't see anything prohibiting this in
NFPA 13, but wondered if I have missed it.
Thanks,
Jamie Seidl
