Hi all...I'm trying to remove this wall fan in a 200 year old house. It =
vents into the "garage" right behind some cast iron drain pipes and =
those pipes are blocking me from just pulling it straight out so I'm =
trying to pull each half out from its respective side of the wall. (I =
don't know how they installed it- I would have expected the pipes to =
pre-date the fan but the fan is probably 70s vintage so maybe the fan =
predates PVC and plumbing was added in the years between the fan and =
PVC).=20

Anyway, the fan looks to be this style/model:

It appears that the fan is in two sliding pieces so it can adjusted to =
the thickness of the wall, but I'm having a real hard time separating =
the two halves even though I don't see any mechanical fasteners holding =
them together such as screws you'd see on ductwork. I can't see the =
outer perimeter of the fan because of plaster, insulation, etc.=20

My question is, if you've come across this type of fan before, and are =
there any other interlocking mechanisms that might be holding them =
together or is it just 50 years of crud? Prying on the inside half's =
rolled lip just makes a lot of "dust" when the pry bar eventually slips.=20=

I'll attach the best photo of mine I could take but I don't think it =
will be of any use. The nut/bolt you see is only holding an outlet to =
the vertical bar and also the bathroom side cover, and was removed.=20

thanks,
jim
