Hearthstone High draft

[Northern21]

I have the hearthstone heritage. Really like the stove a lot. Just wondering if anyone else has a really high draft situation. The control to shut it down doesn’t do a lot. It does some but not enough so that I ever have coals in the morning even if I pile it with hardwood. I have a straight double wall pipe that is about 25ft. I have tried a damper key on my last stove which didn’t do anything. I checked for air leakage. The only thing I found is that air sucks up the pipe at the base a bit. Seems to be attached well. I’ll send a pic. The people who installed it told me that it’s not air tight there. Anyway is there any way to slow the draft down. They suggested two damper keys but that seems crazy. I can live with it how it is. I have got used to it and shut it down quick but there must be something.

Thanks

I have a Mansfield under a 20' straight stack and don't have that issue. 25' would be pulling hard once it's up to temp. The air intake by design doesn't close all the way so coupled with high draft from the stack I could see the stove being hard to calm down. If you where to check the draft with the stack running at temp I'm sure that where you would find the culprit.

I don't think a little seepage at that joint is doing it, it would less lessen the amount of air through the stove by pulling through the crack.

A damper is the way to go as a cheap start. I just paid 11 bucks for a universal damper I put into a 6" section of double wall stove pipe on mine. I don't have to use it normally but have had to calm the stove down after a hot load several times.

2 key dampers isn't excessive when you have a really strong draft, pulling air through the stove.

Also, check your door gaskets for leakage. When it's running, go around them with a punk or incense stick and see if it pulls the smoke in,

Or the dollar bill test (when the stove is cold).
