Internal Vents

ng4265October 12, 2013

I've had lots of experience with fireplaces of all kinds. However, I just moved into a house that has a large brick fireplace with two covered vents on the back interior wall. A metal door will completely cover them or expose them, as needed. I have never seen vents such as these.

What is the purpose of them? Should they be opened to help with the drafting up the flue? Are they some kind of "blower"?

They look to me like vents for the fire to draw outside air so it doesn't draw your heated inside air. I think you can close them when you're not having a fire so you don't draw in cold air. I, on the other hand, have an intake vent that does not have a cover (or it's missing) and am trying to figure out something good to cover it with. It is long and on the front floor of the firebox.. Anyone have a suggestion?
