On Wed, 3 Jun 2009 15:48:00 -0700 (PDT), a certain chimpanzee,
randomly hit a keyboard and produced:

2 rooms can be taken together for purge ventilation if one does not
have windows (just checked in the approved doc)
So I can purge vent the toilet through the hall but perhaps not via 2
other rooms.

And no door between the two. How exhibitionist are you?

Some fan with overrun yes. Don't think a tiny bog needs 15 min over-
run in reality. How many air changes is that ?

That's what it says in the AD, and if you want your plans passing,
it's best to say that.

Most fans come with a variable timer, usually from one or two minutes
to 20. Set it to 15 until the BCO signs off your work, then set it to
whatever is needed to get rid of the smells.
