Venting a Old Coal Baseburner...HELP!

OK....I might get a allot of eye rolls for this one but it doesn't hurt to ask....I have a existing brick open wood fire place. From floor to top of brick is 30inches. Yes I have had the chimney checked out and according to the guy it looks brand new for being almost 100 years old (clay lined)...NOW...I have a restored antique base burner which to the bottom of flue is 28" and top is 34" (yes yes a 6" flue) ...Now obviously I can not just pipe a 6" flue strait back and up into the chimney.....(here come the eye rolls I think)...Can I attach a "flexible" stove pipe and come off the stove... drop down under the brick (a foot and half at most in length) and then up the chimney?....Will it mess with the draft that much?..is this a no no?.....any ideas?...other then removing some brick.

Smoke no like going downhill...
Have a proper thimble put in above the smokeshelf to vent your baseburner properly...

what capecoaler said, have a thimble installed above the smoke shelf and then just keep the damper on the fireplace shut tight. This is also nice because it's easy to clean and remove as well as being able to go back to a fireplace should future owners want that.

Thank you guys for your answers........The stove pipe going up the chimney would be going past the smoke shelf where it would be tied into the clay liner and then up....Thought about going above mantle and tapping into chimney but in my situation some things I'm trying to control...Cost... and my 52" flat screen mounted above the mantel. Thought about moving the TV but there is no other place in my living room to place it. So if the smoke wont like a couple inches of down slope for a length of 15"........... My other option is to cleanly remove a couple bricks at the top of fireplace opening and reinforce it. (yes I will have a stone/brick mason look at it first)....Last option is to place stove in corner and plum it out the wall and up the side of the house. But trying to avoid the cost of that adventure!.....

OK ...I just re-read what I wrote in my first post and I think I may have said it wrong...I DON'T want to "drop" a foot and a half down from the back of the stove, then back, then to a 90deg angle up the chimney....More of a 6" flexible stove pipe off the back of my stove, strait back and the bottom half of pipe would go under and the top half would hit brick. Now being flexible... bend it under the brick a couple inches so it clears the brick then back to a 90deg angle and strait up the chimney....The way I wrote it makes it sound like I want to drop it a foot and a half right from the start from the back of my stove...Or did you guys know what I was trying to say?......the length of the pipe that would be "tucking" under the brick would be only about 15" in length...(that's what I meant)...should I take pics!..lol..Im horrible at explaining things!

No I understood it was just a minor dip in the pipe...
Damm TV's always in the way...
Could the TV be brought forward enough to run the vent behind it...
Might need some $ to do it but would be cheaper than the exterior metal chimney...
Any chance of going in on the side of the chimney or from behind if it is an inside chimney...

you would kill the TV in time with the heat....So I take it its still a no on a small dip huh.....I think the best way is to hire a mason and remove a a brick or two...do it clean so if one day I want to replace them I can do so.......

The base burner will put out more heat than an insulated stove pipe...
Done properly it could be done in a chase less than 18" deep...

your TV will get killed anyway with the heat. you can't put the TV in that location, so, knowing that, go ahead put a thimble in and do it right. Knocking a hole in the stack and mortaring a thimble in won't cost you much, especially if you do it yourself.

Just to clarify the TV and heat...
Regular fireplace has a mantle..
If the mantle is deep enough it will protect the TV from the fireplace...
This is done all the time with Gas Fireplaces...
Problem here is the BB stove will throw more radiant heat and the TV will cook...
It has no protection like it did with a fireplace...
The fireplace is below and behind the TV...
With a BB it is now in front throwing convection and radiant at the TV...

Post a pic of the fireplace area wide shot...
So we may offer some other ideas...

ok I will take some...GREAT!....Trying to solve one prob I have created a 2nd one!....lol..(pics to come)

Heres a wide shot

how high past the opening is the smoke shelf?
Is there a metal damper?
24" from opening to mantlel?
If the smoke shelf is low enough the flue tile might begin in that 24" of brick...
If that is the case you could put the thimble in the brick work...
The TV might be far enough away from the stove...

Is it possible to take the legs off of the stove to get it lower? Or put shorter legs on it? Or perhaps removing a few bricks on the floor will make it fit.
