Hi all,

I'm in a home with a fireplace for the first time and I noticed that
the flue lever has notches cut into it that would allow it to be
partially open. *It would seem to me that a flue should always be
completely open when the fireplace is in use and completely closed
when it is not, but it would appear there is something I'm missing.

I've seen this on other flue levers as well. *Is there a better way to
use a flue when operating a fireplace?

Thank you TH and Don for your answers. I just want to post one more
that was emailed to me from Robert which agree with yours. His answer
was pretty detailed and is probably very good advice.

When you first start a fire in the FP, you will need to have the flue
open all the way. Once the chimney and flue have heated up and
natural
convection begins to take over, you can close down the damper as much
as
possible. Keep closing it more and more until it begins to allow
smoke
into the room, then open it back up just a bit.

A fireplace is a really bad way to heat a room due to the fact that a
tremendous amount of air is drawn out through the flue and this
creates
a negative pressure in the house. This draws in cold air from outside
wherever it can get in. Therefore, closing the damper down, limits
the
amount of air drawn out and conversely the amount drawn in.

In addition, it helps to have doors on the fireplace that you can
close.
This further limits the air drawn out.

In addition to the airflow drawing in cold air, the rapid flow of air
over the wood acts like a bellows and causes the wood to burn even
faster. So you use more wood and stay colder, unless you close down
the
damper.

NOTE: Badly designed fireplaces may HAVE to have the damper open
completely or they will smoke up the house. You will have to
determine
whether you have a good one or not and whether or not you can close
down
your damper.
