I built a very similar stove as you have here. Reversals are common when the chimney cools down enough to reduce a natural draft. I ended up making a draft inducer on the exhaust side of the stove. No more issues. I got tired of the constant needing to feed and built a brick lined box that accepts more wood instead of the taller feed tube. We are able to burn around 4 hours each load. Better sleep too. I like it that on yours that you can remove the lid on the larger chamber for cleaning and monitoring. Stay warm!
0:03 in case of reversal, have an elbow that fits your intake on the one side facing up and a plug that fits the other side. Keep them with your sand and if you need to put it out install plug and elbow and pour in the sand. This way, even with a flame coming out the intake, you can still pour sand by gravity into the chamber without having the mess and loss of sand.
I love my liberator. If it’s that cold use a propane torch and blast it past your sticks and keep your front gate open a bit to get your air flow. Thanks for sharing your journey. I definitely love the pellet option. Gets me through cold nights.
You can get 4" dryer pipe elbow put it on the cold air intake and then just pour the sand into the elbow. You can also get a 4 " cap for cold air intake. I painted mine with black stove paint as it's silver .
Or a metal scooper kept with the sand. I also got caps & painted black to block intakes when not in use. Keeps it from pulling warm air out & up the chimney.
CALL YOUR STOVE MANUFACTURE IF YOU’RE CONCERNED! but AFTER 35 YEARS IN OIL AND PROPANE HEAT …..one 90° bend in the intake or you could even put 2-45s and go straight out next to the stove that would be a great set up then you wouldn’t be burning air that you’ve already spent money to heat! Remember when it’s sucking air out of your house that means ……every little tiny gap around a window or a door is magnified times 10 or 20 OR MORE😝 thanks for the video. Can’t wait to see it hooked up.😳❤️🔥🇺🇸
Just a suggestion, you could prime the flue on cold days, a small paper at the base of the chimney would get the draft going in the right direction.... if you have a clean out somewhere appropriate.
Yes, I find that it works perfectly when temps are in the 20's. Lower than that if I get any smoke or the match tries to blow towards me when I light it I open windows and stay in the room until I see everything is okay. Then I still keep a close window cracked. Not scary, just a tool. Thank you for sharing!
Hi, before starting your stove you could plug one side of the air intake and run a hair dryer forcing hot air to warm up the chimney preventing a reversal of the smoke. Always open a window to the outside before starting the stove especially if you have a second stove in operation. Would house is under a vacuum when your stove is in operation.
Installing a fresh air intake in an upside down U through a wall works well. Warm air doesn’t sink into the pipe and cold air doesn’t rise inside unless there is a draw from the stove. Exhaust fans in a bathroom or kitchen can also cause a reverse flow, bringing smoke into the home.
I had smoke and kindling burning up the feed tube occasionally. The solution wound up simply by extending my chimney height only one foot. I removed a two foot section and replaced it with a three foot section. No blow-backs since.
So here is a suggestion for you! Take it for what it is worth! Next time just cover all the openings because if a stove doesn't have air then it will go out. Yes you may have to contend with smoke but it will never cause a fire with this type of stove anyway. Those fresh air intakes I would get covers made for them. Another option is to put another three foot section on the out side of the chimney.
As an engineer, I battled to watch this. Its a pity that Darvin left town. From building one of these for myself, I know the air intakes in the room like that are tlo big. If they arent conneected outside, the provide a lazy chimney. I experienced also that a blowtorch to pre-heat the chimney in the outlet of the rocket on really cold days. Gave sufficient draw to get started on really cold nights. Also, what probably caused this flame up was air coming through the clean out at the bottom ( by my experience). Sadly i can't make a vid to prove it. The reversal is most likely NOT via the chimney. Ask the "Honey Do Carpenter" 😂 his stuff works!
Long time subscriber, big fan of the channel. I appreciate the videos because you show all the ups and downs. And we can all learn from your experiences. I would recommend making a large funnel for pouring the sand. Because trying to scoop and toss little bits of sand during all the excitement can be difficult. and like you said, it can be difficult to think clearly in those moments. I say make one because most funnels have a narrow exit. And if you make one yourself, you can work out the kinks so that it flows in at max rate. I would think a half pipe (longwise) would be ideal. You could even rig it to a two gallon bucket, with the funnel (or sluice) coming out of the lid (conical lid) at a 45°. If only i could draw a picture in the comment lol. They may even make something like this, idk. Again, thanks for all the work yall put into your videos.
@@dirtpatcheaven I was looking through Lehman's online. In the Hearth section, they had a "coal hod." Basically a bucket with a long lip. Looked like it was close enough to work instead of my earlier idea. If it is too wide, you could always rivet a half piece (longways) of 3" single wall to the lip. Anyway, when i saw the coal hod, i thought of you guys.
if you don't have outside air piped in, all the air that goes out the stack is replaced in the room with air pulled through every crack across the room to the heater. I don't understand why more builds don't have this feature in some form.
On my stove, i used a dryer elbow and hose dropped to the floor and it was good like that. Also, put it up on a fire brick plinth and it will heat alot better.
I'd step up to the next size pipe on the intake to compensate for the 90 degree and then use a reducer where it enters the stove. I'd still use a fire extinguisher in the stove for a flue fire. The draft will suck the fire retardant all the way up and smother it. Another method to put out a chimney fire is to cover the top of the pipe with a piece of plywood. Anything to stop the supply of oxygen will work. Water will crack a hot stove and the flue.
this is certainly an interesting scenario to think about. how heavy is the hopper? because just like you got the slide to cut off fuel to the feed pipe, it might be an idea to have a hopper of sand to be able to douse the flame, though where to fit it in this design? might be an idea to have welders/stove gloves nearby for situations like this.
Thanks good info . Have you ever used those sticks to clean your chimney & or sweep . Video would be great at the end of the season. Thanks again. Glad all is well!
How long does this last while full? I never tried a rocket stove, my king has a 40 hour burn time at full load low setting and 14-16 hours on full open with around 60-70lbs of wood.
We cannot get hardwood in our area. We clean our chimneys about every six weeks. I have trees growing now that are hardwoods so that my grandkids can burn good wood!
Я доверяю вашим знаниям в понимании процесса горения , однако очевидно производитель вас ввёл в заблуждение . Круглые патрубки на приемном устройстве должны быть либо подключены к свежему воздуху , либо заглушены , более того в момент загрузки нижняя створка должна быть закрыта . Нормальным процессом можно считать закрытые патрубки и закрытой верхней крышке , длина выхлопной трубы должна составлять такое значение где температура выхлопа в доме будет составлять не более 150 градусов Цельсия . Чтобы повысить качество сгорания и уменьшить количество дров сделайте новую нижнюю заслонку с несколькими отверстиями 10 мм в ряд горизонтально , количество думаю не менее шести .
The exhaust is not that much higher than the intake, it's no wonder that the heat can't escape quickly enough to create the needed draft for proper air flow. Not the stove I would choose.
What about taking a piece of sheet metal and curling it to make a long funnel that’ll fit inside the air intake so that it’s easier to pour sand inside?
@@dirtpatcheaven I’m in process of having my Liberator installed so your videos are very helpful. I’m in a warmer climate than you, but your experience dealing with rocket heaters is invaluable.
I bought one of these stove and I've had some real problems, the ceramic fiber boards only lasted 2 1/2 months into the burn season causing the 1/8" steel to be exposed and causing the steel to glow cherry red this has happened two years in a row just speaking from my experience I couldn't recommend this to anyone.
Es increíble lo que veo. La estufa en ningún caso tiene que echar humo al interior. Ese problema se produce no por el aire frío del exterior. Ese no es el motivo. Cuando hay fuertes vientos en el exterior de la vivienda si no tenéis un sombrerete antirevocante en la chimenea se puede producir el problema. Lo ideal es instalar un sombrerete statitromb. Este tipo de sombrerete tiene la cualidad de favorecer el tiro en cualquier condición climática. De hecho, cuanto más viento sople, la estufa funcionará mejor. También recordar que la estufa debe tener al menos cinco metros de chimenea con tubo aislado de doble pared. Si cumples con esas dos condiciones, te aseguro que jamás vais a tener problemas de revoco. La estancia tiene que tener una rejilla que permita la entrada de aire del exterior al interior de la vivienda. Si la casa es estanca y ponéis por ejemplo un extractor de aire en la cocina que esté cerca de la estufa producirá una presión negativa que os meterá el humo y el fuego dentro de vuestra casa.
I have an answer for your PANIC N STRESS! Put the combustion air intake on the left side or the right side and on the opposite side instead of a cap …..

And A ❤️🔥FIVE GALLON❤️🔥BUCKET OF SAND INSTANTLY PUTS THE FIRE OUT🌹 ❤️🔥PANIC GONE❤️🔥 God bless you all❤️🔥🇺🇸
Good warning. Otherwise, you are being unfair to the Liberator. You have other wood burners that you gave your very nice and more easy and repair access that other mass heat storages do not have.
This is my sixth Liberator stove video in the last two months. This is a review not a paid advertisement by Liberator. I am experienced with wood stoves and rocket stoves. I want people to understand what they are purchasing. I love this stove and highly recommend it but I want to show people what can happen if they treat it like a toy.
Miss, in the first 7 min of this video I became very worried for you and your family's safety. I work on furnaces for a living (gas burners) and I can tell you without a shadow of a doubt none of the first 7 minutes sounds safe or normal. Please install your equipment as per installation instructions AND AND AND use digital readout carbon monoxide detectors in every room of your house. It doesnt sound like any coincidence that youre having issues with your stove when you are sick, this stove is clearly causing you some problems. I suspect the stove is making you sick, AND THEN you just so happen to notice a reversal later (its clearly happening to a subtle degree more often than you would be aware of, seeing a reversal is evidence that it's been happening when you think it's not). Furnaces and woodburners can be extremely dangerous, dont play around with them no matter your comfort level. If I worked on this system I would be legally required to disable it if the issue was not rectified, as I have with a few others in the past. Please be safe.
The stove should have draft doors, with good seals. Again another disappointment in this production stove......I can shut my fire by closing the vents...
You can put a damper in the chimney. There are instructions on how to do it in the manufacturers instructions. If you have videos of your stove I would love to see it. I will go look at your channel.

Oh what a find! I would love to hear what you think of it.
Just a suggestion, you could prime the flue on cold days, a small paper at the base of the chimney would get the draft going in the right direction.... if you have a clean out somewhere appropriate.
Thanks for the insight. I bought one recently and will definitely be using outside air as I'm in a single wide trailer.

It was just -22 here, -47 windchill, first year with my stove, in the basement and amazingly had no reversals, and the house hung on at 70-72. Whew…

Yes, I have a chimney cleaning video here. I must not have put it in the cards like I meant to. Here it is: ua-cam.com/video/Qza6f4wkZhs/v-deo.html
You need a long neck flexible metal funnel to deliver your sand in relatively the same way your fire extinguisher hose does Julie.
Very good idea. Everyone on here is saying the same thing. I learn something new every day with you guys.
@@dirtpatcheaven
Learning things from you is why we're all here; nice to occasionally be able to return the favor!

Pine wood has a sap in it that burns hot and will plug up and stick to pipes. Might try oak or something else.
We cannot get hardwood in our area. We clean our chimneys about every six weeks. I have trees growing now that are hardwoods so that my grandkids can burn good wood!
Pine leaving pipes sticky is a myth. All woods burn just fine as long as they are properly dried.
Any pine sap is vaporized in that hot burning stove.

Fabricate two metal caps with handles to cover your air intakes.
Great idea! I have seen someone do that and it looked really classy!
Maybe turn the stove 90 degrees to solve fresh air problem?
I have a wood stove insert and there are times I smoke out the house bc of chimney reversal 😂
You get a back daft when your chimney cools down, you loose your daft
with recersal what would hapen if you closed the air intake

What happen to your first husband ?
My first husband? I have only been married once to one man. Jon is my husband and has been for seventeen years.
@@dirtpatcheaven Oh im sorry I was thinking you was married to some one else awhile back. Im sorry..
Could you pour the sand down the hopper?
The hopper was full of pellets at the time so it wouldn't have been able to get to the bottom.
What would happen if you used flour to put the fire out, like a grease fire?
I don't know, where it is coals and a really good draft I would think you only want something noncombustible like sand?
Flour is flammable! Never throw flour into a fire, it would be like throwing gasoline on a fire
