Matthew,
Being one of those "die-hard smokers" I feel
obliged to help my fellow outcasts!
I suggest you get your hands on a
book:
Industrial Ventilation
American Conference of Governmental Industrial
Hygenists
Lansing, Mi.
Ph: 513-661-7881
Library of Congeress Cat Card No:
62-12929
It's written in plain english, with "Do this, or
this, but never that" type illustrations.
I've been very pleased with this valuable resource
for all sorts of building and equipment ventilation issues I've
confronted.
Good Luck,
Ed Popielarski
