Am I going to have a draft issue?

[NVHunter]

I am planning on installing most likely a Lopi Cape Cod is summer and from the stove top I'll have 16.5 feet of DVL pipe to class A duratech chimney above it.

My question is, will I have a draft issue with the chimney height as I'm going to have 2, 45 degree elbows in the DVL above the stove to allow an offset of 8".

My altitude is at 5,100 feet too.

What is everyone's input on my draft?

I know it's not optimal but will it be that bad?

So a total of 16.5 ft from stove top to chimney cap or is that just the connector?

From stove top to chimney cap.

The minimum height is 15 ft from floor to chimney cap and this installation is at about 19ft floor to chimney cap. I think you will be close, but maybe alright.

Yea, doing the math it's 19.5 feet from the floor to the too of the chimney where the cap is. I could add another foot, might help avoid an issue maybe.

I could get the total up to 20.5 feet (floor to chimney top) with 17.5 feet from stove top to chimney top if need be.
