    I'm kind of wondering which route to take, I can just get the chimney lengthened for a few hundred bucks, I would have close to that in the special chimney caps. I do have a fireplace in the house also. The chimney on that one has never had a downdraft issue or draft issue, so as long as I get up to the same height, in theory this one should have no issues either right? The chimney is on the same side of the house, but opposite end. It is a class a straight up though and over the roof line.

    I added that extra section of flue to the top of chimney and have burned it a few days now. It has been burning great since but wanna let it go out for a few days to see if I'm still getting a downdraft when cold. Wish me luck

    in your other chimney are you running a stove as well or open fireplace? There is way more heat going up an open fireplace than a wood stove, maybe that may be a reason that there is no downdraft in your other..even at the same height? HOpe that after cooling you still are drafting well! My aunt still has an awfull smoke problem although she does not thing so!!! They have a soot stain on the inside of the house going up the brick work!!!

    Yes the other one is a open fireplace, but my downdraft issue is while the fire is out not while it is lit. If the stoves off for a few days the basement starts stinking awful, then once I fire it up the smell goes away fairly quickly. The fireplace has never had a down draft issue at all. It's on my main floor and has never had a smell to it.

    I have a 20+ foot chimney and before I put my insert in and even with it in I have a "chimney/soot" smell every so often with it out. but not all the time.

    Where is the other chimney compared to one you are having problems with, what happens is the wind hits the roof and it gets kicked up and then does a nose dive right down your chimney, the other chimney may be in a better place in relation to the wind.

    It's on the same side of the roof just opposite end so the wind still usually comes over the roof first.

    Could the fireplace, even when not burning, be shooting air up and out, causing negative pressure and not letting your stove draft well? And causing a downdraft when it's not burning?

    Maybe shut the damper on that open FP and see if that changes anything. I'm no expert, but my open fireplace used to draft like mad, burning or not burning if I didn't close the damper off when it was not in use

    Just a thought

    good thought dustin. If the damper does not seal well, take some insulation or an old pillow or something and stuff up there to try and get a good air tight seal.
