Hi David,

I don't remember the exact dimensions.  I didn't purchase it, but only
looked at it in the store.  This statement is not accurate, but for example
it was something along the lines of needing a minimum of 20 (or 30 or 40 or
whatever it was) square inches of fresh outside air venting.  For example, a
ten inch wide side window opened 2 (or 3 or 4 or whatever) inches or a 20
inch wide window opened 1 (or 1.5 or 2 or whatever) inches.  I don't
remember it saying anything like the window must be fully opened, instead I
remember something like a specific MINIMUM square inch requirement
recommendation.  Again, I don't know exactly what it was.  You won't find it
on the box, but it was in the instruction manual.

Hope this helps,

Steve
