Just an example of what SS liner costs. Nothing more. Your needs will vary.

The chimney flue for my heater is 20' tall at most.  Possibly less, but it's as Paul described: one story house; installed on the low side.

The need for a liner typically depends on the condition of the chimney and the exhaust temperature. When my ex- installed a high efficiency heater, the lower exhaust temps caused the gases to condensate inside the chimney (1895 house, built inside an exterior wall) and cause all sorts of damage. She spent ~$500 to have it lined. 

She also has a wood stove, but it was a new installation in her sun room and her father and brother (and me to a lesser extent) installed a double-wall chimney through the roof, connected to single wall at the stove. She pretty much only burns hardwood in it, so creosote hasn't been a problem. We inspected and cleaned the chimney after about 3 years of heavy use and very little soot came out. I understand if you burn a lot of soft wood (pine), then soot can be something to keep an eye on.

On the ex's stove, the draft port is built into the stove. I would check with the stove installation manual before installing a draft port in the flue. It has the potential to do more harm than good.

I am so confused now.

Our cape-cod style house was built in the late 40s...its a brick house.  The chimney has an ash fall out too that has an acess cleanout port in the basement.

I’m not sure where you are hung up. The clean out you speak of is not really a concern in your situation if I understand correctly that the stove will be freestanding and not a insert into the fireplace. In some instances the clean out can be used as air intake for some stoves but it is not necessary.

Agreed. The only potential issue I can imagine is if the exhaust for the stove is too high to exit into the fireplace.  But that depends a lot on the design of the stove and the dimensions involved.  You don't want the stove exhaust to make very many turns nor a long horizontal run before it turns up into the fireplace chimney or a draft may be hard to get going.  We had that problem once in awhile, but mainly on warmer days (say, around 40 deg F), and once the fire got going and the exhaust was hot the problem went away.

Ok, no reason for confusion. 

Your original post was an acceptable approach. You seem like a capable guy- make the elbow, slide it in. 

Most of the posts in this thread are describing relining the flue which is a good idea (for efficient burn), but not necessary. 

The only thing I would recommend doing after you are installed is making sure you have good draft. In other words, it should suck air in through the air intakes.

You line the flue for safety as well as draft. If your going to have a fire inside your house take the appropriate steps to prevent a chimney / house fire. Short cuts are dangerous. You wouldn’t race your car without safety equipment and you shouldn’t install a wood burner without following proper safety practices.

Well heres a curve ball...

I saw yesterday a house that had a chimney tube coming out thru a basement window.  Since this stove is maybe overkill (its a fisher Grandma bear i figured out).  Im wondering if I should put it in the basement and run a new separate chimney out the window like that.  Would that be a better overall heating solution?  Then my fireplace can stay normal(and probably unused), & I keep my living room space normal. 

I feel it may be a overall safer total solution & now my wife is gregnant (my name is greg...get it??)  I gotta think of a little one running around.

You would still need an upright in order to get proper draft.  It may have to go above roof level.
