Would it be better two use a 45 with a short striaght piece than another 45 instead of 1 90 elbow stove pipe.
 
I suppose.... but why? Lots of people have a 90 elbow then out to a T and their stoves work fine.

If you want a better answer you will need to give more details, full info about chimney and stove being used.
 
Is it better to have two turns than one? Usually not, but it can depend upon the situation.
 
Either way the stove pipe that is connectiing to the T is perpindicular to the chimney pipe. I do think that the 2 45's would make cleaning a little easier though.
 
When draft is marginal and you want to assist the flow of smoke upward as much as possible, this combo can help. Another case where it might be beneficial is when the horizontal run exceeds a few feet.

We installed the flue system in a yurt last fall. It had a short stack connected, so we came up off the stove with a double-wall 45, then a short connector, then another 45 into the exterior class A cleanout tee on a 12' stack. The reasons were that this was a short flue and a cold one. The stove was shallow, so we wanted to assist the draft as much as possible. It's worked out pretty well. There's occasional smoke spillage on warmer days when first starting the fire, but overall, it works pretty well.
 
My stove is pe summit classic, double wall stove pipe setup is as follows, 36" up then 90 bend than 6" horizontal which connects to the 2 foot selkirk cf horizontal chimney than tee then 19' up.


Smoke does come out the door when i open it even when the temp is 700
 
Does smoke come out even when the chimney has just been swept and the cap removed and cleaned?
 
we was having trouble with smoke coming out the door when the stove was hot and flew was hot , we added three feet to our outside pipe and that fixed it , we were not high enough above the roof top for a good draft . h
 
The chimney does go about three feet over the peak of the roof, i could add another section to the chimney but if i put a 3 foot piece on that would make the chimney about 8 feet tall on the roof. Also being outside chimney it just might cool the chimney instead.

If the cap is clear and its still doing it, you could try temporarily extending it with some cheap galv or black pipe to see if it helps.

Is it possible the wood has too much moisture in it yet? This would create more smoke and lower flue gas temps which can cause a smoke backup. Do you get a lot of black on the glass and top of the bricks? Or does the wood sizzles at all?
 
I will take the cap off tomorrow and see if it makes a difference when burning, i burn dry wood and when i clean it onec a years there is just mostly fly ash a cup or two at the most.
