Should I to use outside air and purchase an OAK?

[vermonty]

We're awaiting the install of our Hearthstone Green Mountain 40 along with an interior chimney later next month. I'm trying to decide if I should install an outside air kit as our 9 year old home is fairly tight. This stove has a 3" OAK available.
Unfortunately, our stove will be installed at an angle near a wall (but not in a corner). The back of the stove may be ~1-2 feet from the outside wall.
I just found an Energy Standards test that was performed on our house when it was built. Here are some 'air sealing' numbers from this document that may help in answering my question:

1. ACH50: 2
2. CFM50: 413

I can wait until the stove is installed to decide, but if you folks think it's a 'no brainer', I'll start planning for the OAK install now. If I do get one, I'd want to incorporate some type of shut-off of the outside air vent when the stove is not in use.

With thanks.

An OAK may be beneficial due to the tight house sealing. One thing to consider, is the proposes outside location for the OAK intake on the windward side of the house?

Yes, and there are damper mechanisms available.

Make sure it's insulated, to stay below stove level at the oak intake, and have a 'P' trap in the duct.
