We're trying to set up another stove, with new pipe, and I'm just wondering why we need both. If a bypass damper restricts the flow of air out of the stove do we actually need one in the pipe at all? This is a 24in box Baker style stove, not an insert.

Thanks for your advice!
 
Yes, you might need both because the EPA will not allow the one in the stove to create a non-clean burning condition. The one in the pipe is not regulated.

So the one in the stove IS regulated? I don't understand the difference, or maybe just the term.
 
Bakers are coal and wood stoves. No regulation to it. I didn't know they had a "bypass" damper in them.
 
Oh, I thought you had an actual modern EPA wood burning stove. The EPA regulates the emissions from these stoves and therefor prohibits the user from being able to close any damper very far. The bypass dampers simply force the smoke in a less direct path to the flue.
 
No, we have an old woodburner, probably over 10 years old. We went ahead and installed both. I got lucky and found the damper at a small local store who normally doesn't carry them. Thanks for all the advice!
