Yes that is true about the house could be pulling on the chimney, but in that case the house would be full of smoke pretty quick. And also there are the vids of the smoke rolling pretty vigorously past the baro opening.

Agree on possible other issues - and wet wood would be my first thing I would question. But it seems that has been addressed. And I wouldn't expect any wet wood like issues, an hour or 2 into the burn like here.

Quite a saga - no matter the outcome, I am really curious what it is or will be, no matter how it turns out.
No it wouldnt fill the house with smoke unless the negative pressure overpowers the draft of the chimney. If it doesnt it will just cause performance issues like slow startup and backpuffing.
 
Yes true, this seems to be the extreme example of the issues. but I guess with any issues, there has to be an extreme end somewhere.

Getting a pro in would also be good, not sure what the local situation is for that there. Any independent WETT inspectors around? An independent assessment about the furnace design would also be interesting - but even harder to find or get, and likely not small $$.
We have no wett inspectors here. In the states you would get a chimney sweep

You need to look at the bright side. You now have something to hold a really big door open with!! ;lol ::P
 
So this was just pointed out to me... The SS liner that I had purchased had a shorter t-snout (it is being replaced with the correct length) and where the seams are welded together you see where air is being pulled in. The thought is this fresh air is causing the back puffing.

Thoughts?

Well, personally I would fix that, just because...but I highly doubt it is going to affect the problem one bit.

That would not cause backpuffing like you have. Especially when you have a barometric damper in the pipe letting in air.

No way. As I think I already said on similar theory a page or two back. :)

So that small bit of air is one of the root causes of the "puffs" in the stack?

If so, that doesn't explain @Medic21 having "puffs"
I seriously doubt it has any effect at all. And i also doubt the puffs are in the stack. It is probably in the stove it just shows up in the stack because it is the path of least resistance. The chances of you having enough temp in the stack to allow for ignition of those gasses are very slim.
 
Just would like to confirm the following...

The Kuuma, Caddy, Drolet and other stoves mentioned in this thread have some sort of "auto" draft control?

Edit: “auto” primary air control

They all have an auto DRAFT control....it's called a barometric damper.

Kuuma is the only one which has a fully automatic controlled primary air damper based on internal firebox temps.



Some who have Tundra's have made their own damper controls using flue temps.

Caddy and Drolet Tundra/Tundra II, Heatpack, HeatPro all have a motorized flapper over the primary air inlet. It is either wide open, or closed down to a minimum of a 3/4" hole opening. There is no in between control of the flapper like the Kuuma has. The Secondary air inlets are always open.

The factory control of the primary flapper is open when the thermostat is calling for heat, or a manual air inlet switch is in the "on" position. The factory hi-limit will close the primary flapper when tripped.

Some of us have fine tuned that open /close flapper based on flue temps, in my case I close it if it hits a selectable high flue temp, and open it if it hits a settable low temp. More of us have added a spring loaded "hot tub" timer to hold the damper open for cold starts or reloads to char a new load of wood and get the firebox up to temp. These are the reasons I can throw a load of wood in and walk away with no concerns. No leaving doors open, etc.

No. What I meant was, no way does that cause your puffing. As I also said re. a similar 'engineer' theory a page or two back.

That's the key right there...and the reason these FC's will never work properly as they are designed now...IMO of course
 
I skimmed this real quick...I will read the rest later...I assume you linked that due to the cool chimney part...if that was your issue you wouldn't have draft...and you do per the Dwyer...now, that said I understand @bholler s point from before about the meter could be showing "house draft" and not chimney draft...but I really doubt that is your issue...I think the chimney is fine and it is a stove issue.
Did you ever have this problem with your old stove...no? If not then I'd say that's very strong proof it is an issue with the FC1000
 
Zero issue with my old Huntsman stove.

Perhaps a combo of things?

My newbie opinion.. The stove is filling with smoke faster then it can be cleared/burned due to fixed draft blower air intake opening.

Should of asked more questions before buying the stove.
