Can you get to much draft?

I was not drafting like I felt I should and am considering putting another 2 to 3ft more flue pipe on the chimney. Could I get into a situation of having to much draft and could I control it with inlet air only adjustments.
Stove is double wall. I don't know if they make flue dampers in double wall. If so probably $$$s.

 

Yes you can get too much draft...but unless you have a very tall chimney, and you obviously don't, it can usually be controlled by the stoves controls...and yes, double wall damper is spendy.

 

I have double wall damper equipped appliance adapter section. It was like 38$. Almost the same price as a non damper equipped appliance adapter. It’s the little 6” chunk right on top of the stove.

No stove went from too little draft to too much draft by adding 3 feet. The happy middle area is luckily quite large.

 

My house has a section of flat roof. Like it was suppose to have a copula (sp ?) and they never added it. Prevailing wind is from the west and chimney is on the west side. Not sure my chimney extends above the flat part. It would be close if it doesn't. The idea would be to make sure it is above the highest part of the roof.

 

Cupola was the best way I could describe it. Here is a picture. The height of the chimney is deceptive from a ground level angle.




Edit to add a different angled shot. More realistic.

 

General rule 3 feet higher than any roof within 10 feet..

 

Yes, that's the minimum.

 

Yes, SS liner.

 

Hey Marshal, Looks like you've got lots of good answers from others so far. I agree with all. Very difficult to wind up with too much draft without trying very hard to do it. Even so, a good airtight stove shouldn't have any problem with that.
As others have said, looks like the chimney should definitely be higher, for clearance to the flat section of the roof and maybe to improve the draft but height is only one factor in the draft equation and I can see a number of problems in your chimney structure just from the pictures. I think you would be well served by calling in a trustworthy chimney professional. At the very least, your chimney needs some significant maintenance.
When was the stainless liner installed?

Couple pictures of the stove area and how it connects into the chimney may help too.

 

SS linear was installed about 6 years ago and has had annual maintenance. Chimney is clay lined with 6" SS linear.

Vertical run is 42" Horizontal 26" Chimney folks said I chimney was 22' heigh.

Have to make an appointment with the chimney people for this years maintenance and will run adding more height by them.

 

I believe it is level. Easy enough to correct. Vertical section is adjustable pipe.

 

Yes, the horizontal connector pipe needs to be pitched. Would be even better if you could eliminate that 90˚ bend with two 45's and a short straight section in between.
I'm wondering how the chimney people clean your chimney, from up top or at the stove? I see a lot of flues clogged & restricted right there at the connection because they aren't cleaned properly.
Just a guess here... You had the flue relined after damage from a chimney fire? Just wondering when all that cracking in the block structure happened and what condition the crown is in on top. Two important maintenance issues that get neglected till they become bigger, more expensive problems.
Chimney companies can be like Used Car Salesmen, need to be careful who you trust.

 

I put a damper in my double wall. I put a nut on each side of the pipe (between the inside and outside pipe) as spacers to keep the clearance between the two. I could only do this because the damper is near a joint though.
