Too Much Draft

[kubotamike]

I recently had a new Pacific Energy Super Le install along with a 22-24' Ventis Stainless Chimney and 50" of ICC double walled stove pipe.
Ever since the install I've been unable to control the fire as it has too much draft .

Last week the company who installed it did a draft test and it was at .10 on their gauge so they installed an ICC key Damper .
Since the damper was installed it has slightly made it better but even with the damper closed and the stove draft shut down I'm still not able control the fire and get secondary burns. Even when I light the stove there is so much pull it will close the stove door I have to hold it open . I've checked the door seal and the ash dump seal and they are both okay.
Any Idea's on how to tame this beast down !

they installed an ICC key Damper .

Did you see it?
That is the most "open" damper that I've ever seen...better than nothing, but just barely!
I think you need to either install some fender washers over those holes (washer on each side, bolt through) or since there are so many large holes, I think I'd just get some stainless sheet metal, cut out discs the same size as the damper blade, then bolt through.
I doubt the installer will be willing to do that, so hopefully you can diy it.
If not, then you need to find a different brand damper to put in there that is not so "see through"

Yes, that's a pretty leaky damper. There are other dampers that close off more air. You never want 100% closure, that would be dangerous, but 75% is a good initial target. This is a typical aftermarket pipe damper.

Yes I seen that there are large holes and wondered about that . If I cut a piece of 16 gauge steel large enough to cover the ICC side would that be enough ? And either bolt it or tack weld .

That could need another damper depending on how many elbows.

Try that for a start.

I might be able to take off the top 2' of chimney, not sure if it would help but can't see how it would hurt .

Be sure that the chimney still meets the 10-3-2 rule requirements. If so, yes, removing 2 ft can make a difference.
