Hello,
I do not see a number specified in the N600 shop manual. Searching the archives here provides three numbers/ranges:
Miles: no more than 7-10 inches (presumably inches HG)
Bill: at least 14-16 inches (presumably inches HG)
Neil: 10 psi
Converting to mmHG gives, respectively:
=400 mmHG =500 mmHG

Can anyone chime in to support any of these numbers or put forward another?
Thanks,
Jesse.
