We had our chimney lined 4 years ago and despite the company's claims
that lining the chimney wouldn't effect the draw, it did. We called
the company back 3 times to correct the problem. They placed a fan at
the top of the chimney to draw the smoke out, but this didn't work.
They replaced the fan and it still didn't work. They claimed that the
draw was fine but it wasn't. We had another company come and run a
video through the liner to be sure there were no problems along the
way, and it was completely clean, sealed and clear.

We finally gave up and haven't used the chimney since. I would like
to remedy the situation. What might make this chimney work again? A
stronger fan? How strong? Altering the opening to the fireplace?

Assuming that the chimney is being used for a standard fireplace, I'd recommend
buying a "certified" fireplace insert. They use smaller chimney pipes (mine uses
6") to work properly. You'll get big bonuses on heat to the house. Instead of
sucking most of your house heat up the chimney, they will actually heat the
house. With a big glass door, you still get the fireplace ambience.

The only problem with mine is that the fan needed to get the most heat from it
is pretty noisy.

My insert has a continuous metal liner fitted to the stove top to the top of the
chimney, which is really nice for cleaning. All the debris ends up inside the
stove, and you don't need to remove the stove from the fireplace to clean the
chimney.

I used to have a year-round creosote smell in my house from the fireplace
because it would backdraft frequently. By sealing around the stove well when I
installed it, that has gone away.
