100 year house / attic - install attic or out side wall and up the side?

[CKennedy]

Long story short..

Concerns on using attic in 100 year old house / vrs routing out side wall and up ..

Attic 48" +/- to roof line
24" or even 36" duratech connection box and shield +/-
** what about the 12" down from the roof line into attic?? Not being shielded!
Duratech class A double wall!
etc..
$$$$ .. $2500 -/+

In being honest i am just getting a lot of bla, bla about running stove pipe up my 100 year old attic.. A lot saying it would be safer to run out the wall and up the side.. "Must admit" - I like not having to worry about attic issues / in use or install!..

Being in North Carolina, Winston Salem area, would double wall sirlink work going up the side, without being incased in a box! Work .. So:

Out top of stove 24" if possible, angled to thimble in wall, then 12-14?? inches to tee, up the side some 11- 13 feet.. Have to get that measurement..

If I remember correctly - I could save $1000+/- total pipe. ..
