After a chimney fire you definitely need either a visual (remote-controlled
video camera) inspection to make it's still safe or to assume it's not and
line it with stovepipe instead.

I know of lots of people who have run stovepipe inside chimneys. It almost
always improves the draft of the woodstove – especially if you go higher than
the original chimney's height. Triple-wall would be an unnecessary expense
inside the chimney, in my opinion, unless chunks of masonry were lost in the
chimney fire. Above the original chimney line it may be worth it to keep
smoke/creosote from liquefying in the sudden cold.

Another thing: Instead of tilting the pipe, you could simply replace the
elbow with a T, one opening of which would connect to the stovepipe above,
and the other which would be fitted with a "clean-out cap" inside the
fireplace. That would allow you to scrub the chimney from either above or
below and discard the creosote. Frequent cleaning of the stovepipe or chimney
is crucial to safe wood heating.

One thing more: You probably already have the front of the fireplace closed
off with sheet metal or some such covering. You'll need to keep this in place
or seal the damper opening around the stovepipe to make sure you're not
losing a lot of already-paid-for heat up the masonry flue.

I apologize for this off-topic. I am really stumped and could use the help
of DIY folks. We were brought up doing construction/remodeling/farm
building projects, so we can do most projects ourselves.

Is there any reason a woodstove should NOT be place with a stovepipe going
directly into the chimney? Should there be a elbow?

We have a woodstove sitting 90 degrees to the wall where the chimney is.
There is an elbow at the stove end and then 2 feet of pipe to the wall with
about a 25 degree slant upwards. This is an inside chimney.

We wonder if we could turn the stove, so the hole in back of the stove is
straight across from the chimney with a stovepipe of about 2 feet slanting
upwards 25 degrees.

The reason: We have had this set-up for about 12+ years. (This was here
previous to moving here.) We have had an increasing and alarming amount of
creosote build-up in the stovepipe. We replaced the stovepipe with a new
one last year with little improvement. Got a nasty fire last year and don't
want a repeat. (roaring train type)

I also wonder if the draft is just not right. Sometimes you can smell soot
in the house when running in winter and not running in summer. MAYBE the
stovepipe is too short???

We are doing some insulating, so the house is going to be even tighter. I
got a drafty door across the room from the stove that I am replacing
tomorrow with a steel door.

I really want to do this right. We are considering moving the stove and
using triple wall chimney pipe instead. But it is expensive. There is alot
of other work (money) needed elsewhere in this house!! :-) ya know how it
is . . .

Time is also against me since it is cold enough to start a fire now. Yup.
We just had to wait until the last minute! :-) (Actually we waited until
our steer was sold to use that money if necessary to build a whole new
triple wall chimney )set-up.
