i am venting my Axeman Anderson AA130. it is about 3' from the flu. so it will have an elbow and a small section of pipe running straight to the chimney. do I need to put in one of those draft control pieces. this is my first set up...im pretty sure thats what its called (it has the flapper on it). or can I just run it to the chimney with the regular vent pipe??

You need a "BARO" or BAROMETRIC DAMPER, these are Automatic once set. Do Search on here on this topic.

They help maintain the correct draft on your stove without wasting heat/fuel up the chimney. The more heat generated, the more draft you will have that will suck more heat from your stove (Where you want it!).

If you don't have one, you waste more heat and/or fuel up the chimney.

On this forums title page (Venting, Plumbing, Chimneys, etc.) there is a sticky post on baros, a good place to start. Here is another.

Axeman Anderson says to install a barometric damper, If you have a tall strong-drafting chimney, it can keep pulling air over and through the coal fire, even when the boiler's combustion fan is not running. This can result in higher water temps than you want or even over temp water requiring a dump zone to control..

So unless you have a short, marginal drafting chimney, I'd install a barometric damper,, AA says to install it at the end of the flue pipe, at the entry point ot the chimney.
