I have seen many posts regarding the smoke going into the room. I have
an open fireplace and I have outdoor air brought to fireplace. But the
smoke is still coming into the room. If I open a window (located on
the other side of the room) just a little bit, everything works fine.
The problem is that I don't want to have the window opened, and I
brought the outdoor air to the fireplace just because of it.
Does the direction and/or location of outdoor air income influence the
Thanks in advance
Some, but mostly smoke comes into the room because it's easier
than going up the chimney. If you've got an air supply feeding
the combustion chamber anyway, consider sticking a tempered
glass front on the fireplace. That will keep the smoke on one
side, and your expensive heated houshold air on the other.
Thank you very much on your answer. It is an old traditional hearth
that needs to be opened. It doesn't serve for heating, just for
preparing some traditional foods on it. Many people have such a hearth
and some of them experience the same problem, the others don't. I
tried to do everything to avoid it. My chminey is wide and tall, the
outdoor air is coming directly to the hearth and it can be seen that
the air is coming because when I open the air door, the fire gets
bigger and stronger. But the smoke is still coming into the room (not
very much but enough to feel unpleasant sitting in the room). And if I
open the window, then there is a air flow between the hearth and the
window and is not very pleasant too.
I don't know what could I try else, if you have some advice, I would
appreciate it very much.
No offense intended, but in my limited experience, chimneys need to be
I will build my fire, small, medium and large wood, and with my first piece
of newspaper, establish a 'flow' (kinda like a siphon) thruogh the chimney,
well above the combustibles.
Just before the newspaper goes out, I will light the small wood.
Really seems to improve my percentage of woman-impressing fires.
Well.. if you're not concerned about heat-loss, you could try throttling
back the outside air supply that's feeding the fire. That should
force it to suck air out of the room in order to feed the chimney.
Other than that, I think you're stuck with draconian solutions
like re-building the combustion box, or flue, or pressurizing
the room... You're not running fans or anything to pull air
out of the room through doors and windows, are you?
If you stick a wire flyswatter near the flue opening
while the fire's going, are you getting a good draft?
it seems as tho there is not enough draw to pull the smoke up the chimney....
had a similar problem... turned out to be a broken flue damper....when i
*opened* the flue, it was only opening a mere 1-2 inches..not near enough for a
good draw...since it was made of cast iron, i opted to put a new chimney top
flue damper in place.... stainless steel cap and springs..... now my wife has
returned to being her pyromaniacal self...
