that barometric dampers get installed on wood boiler & furnaces but not woodstoves?

I sometimes stay awake at night thinking about this - oh, wait a minute, no I don't. I stay awake thinking about pulled pork samiches and beer. My bad.

Okay, pook, I just have to ask...and understand I ain't flamin' or hatin' in any way. But are you convinced that every stove (or at least 8.5/10) is going to overdraft? I can't count on both hands/feet the number of times I've seen the now infamous Gulland's Florida Bungalow Syndrome link this season alone.

I am honestly, 100% genuinely curious.

try pull pork instead of contemplating + more beer faster! = higher octane either way, be4 the aftermath

dunno, but overdrafting can have serious consequences beyond being a temporary PITA.

Fair enough. Suffice to say you piqued my curiosity, that's all.

If you read the whole Florida Bungalow paper, you'll see that the use of a barometric damper to ameliorate the problem wasn't what he suggested doing. Why?

The problem with barometric dampers is, the reduced updraft might adversely affect the secondary burn, reducing efficiency and increasing emissions. Further, the intrusion of room-temperature air into the flue cools the flue gases, causing increased creosote formation. Finally, if the increased formation of creosote leads to a chimney fire, the resulting extreme updraft will pull the barometric damper WIDE open, and could allow the chimney fire to rage out of control.

How will the plastic bag of wet newspaper work if all the air is getting sucked in above the stove?

Lowering flue temps to fix burning problems is never a good idea IMHO. Control of air at the intake rather than at the exhaust is one of the cornerstones of modern stove design theory.

If he ever buys a wood stove or wood furnace he may figure that out.

even safer is to spray water into the baro & not have to open the door of stove, fire extinguisher also=gonna suck into chimni right? baro + chimnifire is bad unless it dont hurt the chimni

While I agree with the worst case scenario, they can be a good thing if used properly. Our furnace has a automatic damper controlled by a servo. Depending on the house temp, the damper will open and feed the fire alot of air. I need the baro to stabilize my draft in the chimney. If I didn't have it, I would overdraft severly and damage the unit. With the draft set to a specific speed, I don't have to worry about that damper remaining open when I sleep. I lined our chimney this year because our flue temps run low. With a good fire with secondary combustion, our temps probably aren't more than 400 if lucky inside. Still we see no smoke from the chimney with the damper closed. Now I have heard of other furnace owners that after 30 days have filled their flues with creosote. They had an older furnace and their flue speeds were set too low. Having a Epa furnace we don't have those issues. Yes it does lower the flue temps, but if its set to a higher speed, it will open as little as possible allowing more heat in the flue. I have been burning over the last month, and we have nothing in the flue or chimney. If you don't have a tall chimney then you don't need one, and if you have an older stove I would say no to using one, but if recommended they can be a good thing.

Whole heartedly agree with you both, BB and BK!

Totally agree. Install a secondary air control and then you'll be ready for anything.

heart feels, brain thinx. modern oil burner uses barodamper to stabilize draft. i see cup of creo from chimniclean & wonder how fat a chimnifire that could produce? LOL

For the same reasons as the other posters say along with not every manufacture wants or recommends a barometric on their wood boiler,gas boiler, oil boiler or furnace. Just sayin me knows eh!
