YOur problem is compounded by having a chimney that is too cold.a
chimney needs to be hot to a certain point, to reduce buildup of
creosote. Smoke cools down in the uninsulated stove pipe, condensing
and turns into creosote. You can get by with a short length but if
its a long run of uninsulated stove pipe outside, it cools to fast.
Also burning softwoods like pine etc and unseasoned woods will all add
to the problem.

Sounds like your not using an insulated exterior pipe. If thats the case
stop using you woodstove NOW!!! You probably won't realize your house is on
fire 'til you see the the fire trucks arrive or your neighbors call.
Go here for some good info on chimneys http://www.csia.org/
Go here for wood heating in general http://www.woodheat.org/

Somethings is wrong. We have a setup with 6" pipe and burn about 3
cords a winter. At the end of heating season, I have maybe 1-2 gallons of
flaky ash. That's it.
1. You need to have insulated chimey pipe to keep the heat up inside
the stack. This will also help with the draw of the system. A good draw
means that the chimney pulls all the fumes & smoke out of the house,
leaving no smoky smells inside.
2. You need to keep the temperature high when you burn. Are you able to
install a stovepipe thermometer? They cost about $10. Install about 18"
up on the stovepipe. You should shoot for a pipe temperature of around
400-500F. This temp will give you maximum efficiency and will put your
burn in the "double combustion" range - this means that almost all of the
gases & smoke will be burned at the highest efficiency & you will see
that your chimey smoke will just about disappear.
3. Burn well-seasoned hardwood. The pine is OK in small amounts when
mixed with the hardwood - but not too much.

Good luck. Better fix that creosote situation before you get a
rip-roaring chimney fire.

Go to http://www.chimneysuppliesonline.com/newsite/
and get their dropdown menu, for 'cleaning brushes-rods'
I suggest triple wallthrough your wall, to a 'T' outside. 'Cap' the
bottom of the 'T' with a coffee can or regular cap. Go about 3 ft
above the roof with the triple-wall. When you need to clean it, take
off the cap, clean from the 'T'. Coffee can should catch drips.
Make sure 'upper' pipes slip INTO lower ones, so that dripping stays
in pipe.
And secure the pipe very well.
After you get a brush, and sufficient rods, keep the pipe fairly clean,
since the most efficient stove is just a little short of smoldering, so
a lot of creosote forms, especially with soft woods.
Some people put the creosote back into the stove for another run, with
its high carbon and low moisture content.
But, if that fluffy stuff burns in the pipe, and the pipe is single
wall, you better be counting on needing a lotta luck, because you'll
have an extremely hot fire, and likely burning pieces coming out of the
pipe. Possibly through a newly burned out portion of the pipe. (Now,
how close to the house did you say it was?)
Hope you live the same place after the winter.

FIberglass is not the material used to insulate with. They use a
quartz silicate fiber or a ceramic bat to insulate chimneys with.
There is also such a thing as a insulated chimney pipe....are you sure
your chimney is high enough to draw properly as well?
I would not use it until it has a properly installed chimney.

Hmmm. The one thing that I didn't see mentioned in all the replies
was the fact that maybe you don't have enough air getting back into
the house. Wood fires require much more air to burn than oil or gas
and the house needs to be able to repelnish the air being sucked up
your stack. Poor draft can result no matter how high your chimney is.
The pipe size may be too small too but I doubt it. Check the
literature that came with the unit. Running an air tight stove is the
worst thing that ever happened. People got too lazy to stoke the
fire but wanted the cheap wood heat. Something's got to give. Air
tights always crud up a chimney if they're shut down low due to too
much heat from them. Once in a while you need to build up the fire
to keep the creosote down but make sure to do it only when you're home
and can watch it.
Otherwise, burn hard coal in it. It's safer, cleaner and burns so
well that the EPA doesn't even regulate it. It's impossilbe to make
that stuff smoke. And the heat is great.

That's because the stove pipe type type and length is a major concern. Why
worry if there is gas in the car if there are no wheels on it?

Burning coal in a wood stove or any other heater not designed for it
is inviting a disaster.....
