Can I make a slight angle with the stovepipe.

I am trying to figure out my clearances for my alcove installation and to fit the stove in the alcove and install a bk scirocco I need 6 inches from back wall to stove. Well I only got 5 inches. I was wondering if I can make the stovepipe angle 2 inches up to the top of the alcove. The stove pipe will be about 60 inches long so seems like not a big deal and no one would probably be able to see this. I am using icc excell ultrablack double wall stove pipe and icc excell class a up the chase. Or should I just leave 5 inches and call it good since the hearth will be finished with stone. I know no professional would recommend going against said clearances but what would you do.
 
Why not just move the stove forward an inch or two?
 
Well that is my intention to just move the stove forward a couple inches. The issue then is the necessary framing for the alcove top will put a slight angle on the stove pipe like I said about 2 inches angle up 60 inches.
 
You said you need 6 but only have 5. Why now are you trying to get 2" of joint deflection? 1" is possible, just don't put screws in until everything is where you want it. 2" is starting to get radical.

You are measuring from the rearmost part of the thermostat cover to the first combustible wall right? Not to the face of stone or durock but to the wood.
 
Not sure I follow the alcove design. It would help to see what is planned. Can you post a sketch or two of the proposed setup that shows the issue?
 
Well it is converting a zero clearance hearth to a freestanding stove alcove. The issue is to get the 2 inch clearance of the class a pipe on the inside wall of the alcove it leaves me a little short on the clearance of the outside wall on the back of the stove to get the 6 inch. I will try to post some pictures later. I am measuring from the back of the stove to the combustable wall per manufactures directions. I will try to post some pictures later.
 
The smallest offset with double-wall 6" pipe is going to be 5.75". What will be the alcove ceiling height off the floor?
 
Thanks for the help. When you say offset of 5.75" is that for 60" of stovepipe does that mean I can angle 5.75" over 60" of stove pipe. Do you have a reference for this number of 5.75". I will post a picture of what I am dealing with so far. The alcove ceiling height will be at about 95"

That is the offset when you combine 2 - 6" 45º double-wall elbows.

In other words, adding an offset to the pipe with four additional chunks of double wall to get a minimum of 5.75".

You can also just deflect the pipe. Seldom is the stove perfectly located under the flue and stoves are known to walk more than an inch.
 
The offset can be at the stove or at the ceiling, 2 - 45's reversed for the offset and one telescoping pipe will work for some setups.
 
I do not want to put two 45 degree offsets. I know I could do this but I would rather just go with a different stove (the PE neo 2.5 for example) than put in two 45 degree offsets. I would hope I could "deflect" the pipe an inch or two off of straight up and get the BK scirocco that I want.
 
Though not my preference an inch deflection over the 6 ft or so of connector could be possible. Personally I like my installs to be dead plumb and straight for the best seal at the stove and ceiling box, but there is some fudge room.

begreen is right when he says, "Personally I like my installs to be dead plumb and straight for the best seal at the stove and ceiling box." That's how I like to do mine, too. However, as he said, there is some room to fudge. I would be surprised if being just one inch off in a 60" run could not give you a good seal at the stove and up top. Put it up and take a look. You should be able to tell pretty easy as to how a good a seal you have and then go from there.
 
Another issue is that the connector pipe will be too close at the support box. This could be shielded.

Nah, if he has 5" at back of stove, he has way more than 6" from wall to pipe. The pipe comes out of the stove several inches from where rear ctc is measured.

Can you move the stove out a couple of inches and use and adjustable sliding stove pipe to keep it straight?

Mine angles back 1 1/2 inches over 5 ft. I've not had any problems yet and you can't really tell because it's in an alcove.
