Edit: ^^ Good post above ^^
Here's a thread that has a pic and all kinds of info about baros.http://nepacrossroads.com/about2303.html
In a nutshell, it is a device that helps keep your chimney draft exactly where you set it, based on your individual chimney, stove, location, etc...
Your manual will tell you what it *should* be for your model of stove.
They really keep things in line as draft changes- as it will with temp, winds blowing, and tons of other factors. With a proper baro setup, most of those factors will be handled automatically.
You'll need to use a manometer to set it up. Many of us install a Dwyer permanently to monitor the draft for any changing conditions. Sort of like taking the pulse and blood pressure, gives you a quick indication of how "healthy" your stove and fire are at the moment.
Here's a pic of my installation, in a thread loaded with installs: http://nepacrossroads.com/post553110.html?hilit=manometer#p553110
