I got this photo from Japanese confectionery cafe Kanamido !
We had a roof construction by ourselves!
It's really amazing!
]]>
The other day, I visited the house of a buyer of chimney components in Ashiya City, Hyogo Prefecture.
It was an emergency situation with only three days left until the scaffolding was dismantled for DIY construction, so I helped a little.
This is how it looked at that time.
The roof tiles are not fixed with nails, so you can easily remove the rest by lifting the first one and dragging it out.
It's easy to repair and replace this kind of tile!
Under the western tiles, there is a cross bar for hooking, but it was an old roof with soil to stabilize the tiles.
Of course, there was no asphalt roofing or rubber roofing underneath, but a thin cedar board roofing material.
Underneath that was a cedar 12mm thick nojiku board.
It seems that the tiles are basically going down a little when it's a storm.
It is absorbed by the groundwork and dried when the weather turns, so rain leakage is less likely to occur.
It's old wisdom.
In addition, remove the tiles and drill a chimney hole to install a new roof support bracket.
This bracket is cut from a single stainless steel plate.
It is stronger than ordinary roof support brackets.
Therefore, construction is possible without any reinforcement, so construction work can be saved.
Insert the heat insulating double chimney and fix it.
After all, work on the roof is especially easy with two people.
While one person is firmly supporting, the other is fixed.
Photo looking up from below.
The cut in the eaves of the ceiling board is shallow, so it will be cut out later from the indoor side.
Keep at least 5 cm away from flammable materials.
Click here for the concept of distance during construction
Since the tile is not stable, it is reinforced with a 35 mm square.
After this, I put the clay I bought to stabilize the roof tile.
I served it on the square material.
My hands are full of clay around that area, so I can't touch my smartphone and take a picture.
After all, good photos and bidets cannot be taken without a shooting staff other than one more worker.
The first day's work ends here.
I put the flashing on once.
There was no rain forecast, but rain measures are necessary to sleep soundly.
For the time being, I used a paint curing sheet that I had around me to protect it from the rain.
Resume work the next day
Attach a blade for concrete and cut the tiles to restore.
I made it like a breakwater with the surplus clay so that even if the rain gets in, it will run off.
I was able to restore it with a good feeling.
I also removed the tiles.
I put aluminum-based flushing under the ridge tile.
With this, there is no need to worry about the rainwater flowing from above getting into the bottom.
Since it is an aluminum base, it can be bent freely to some extent, so construction is easy.
Restoring ridge tiles.
The ridge tile can be removed by untying the copper wire fixed to the base.
When putting it back, insert a copper wire into the hole in the ridge tile and wrap it around to fix it.
I apologize for the lack of pictures.
It is recommended to remove the chimney along the ridge, because there is less concern about rainwater from above.
On the other hand, the eaves (near the rain gutters) are prone to leaks because the rain flows down like a river when it rains heavily.
In addition, when there is a strong wind like a typhoon, there is a risk that the rain will be pushed in even if you do not normally have a leak.
This leads to leaks.
In that respect, it is recommended if it is close to the ridge (top part) because it is safe.
The lower part is deformed into the shape of a roof tile with a rubber hammer.
Double-sided butyl tape is attached to the back and adheres to the roof tile.
In addition, a flushing sheet is attached to both sides and the bottom to prevent rain.
This sheet has butyl tape attached to the entire back surface from the original.
And since it contains an aluminum mesh sheet inside, it will hold its bent shape.
Easy to use as it can be cut with scissors.
Products with a width of 1 meter are sold in units of 10 cm.
About 1 meter was bought, and the surplus part was used up for repairing roof tiles.
Finally, caulk around the chimney and flushing to prevent rain.
The silicon sealant sold at the home center has a heat-resistant temperature of 150 degrees, so there is no problem, but if you are worried, please use heat-resistant caulking.
It doesn't look very beautiful when viewed from above, but it looks like this when viewed from below, so it's not bad.
Thank you for your hard work on DIY work!
Chimneys must be at least 60 cm taller than those within 3 m of circumference and must protrude at least 90 cm above the roof.
This will give you the height you need to be unaffected by the wind and to extinguish the occasional sparks from the chimney to the soot that builds up on the roof.
However, this is only a manual approach.
It must be determined according to the degree of wind in the area and the structure of the building.
Please contact us if you would like to know more.
]]>I feel like the chimney is a little short, but it's scary if it's any longer, so it seems that they will decide whether to add it while watching the situation.
By chance, it was just a short distance from the road to Maizuru College, where my daughter attends.
After that, I was sent a photo.
It was a young couple who had moved from the Chubu area with a small child.
It was a private house with a thatched roof, and the interior was modernized by myself.
There are very few people who install the chimney of a wood stove through a thatched private house, but they did it themselves!
I'm really surprised.
This aluminum-based silicon flushing seems to be easy to use, regardless of its appearance.
Click here for product details.
It seems that the part of the thatched roof was cut with pruning shears.
When it was delivered, it was already cut and ready for the chimney.
After that, it seems that the surroundings of the heat insulating double chimney were surrounded with calcium silicate board just in case.
In Europe and the United States, this insulated double chimney must be at least 5 centimeters away from combustibles, but it's still a problem, so it's a good idea to take safety measures!
]]>It seems that he decided to put the wood stove away during the renovation.
I went all the way to the warehouse in Takarazuka City, Hyogo Prefecture to pick up the chimney and the wood stove.
It was a pleasure to talk with you.
It's really nice to be able to connect with various customers even though it's an online shop.
When the installation was completed in the middle of summer and they tried to burn it after completion, it seems that there was a big backlash from the family (laughs)
Have you finished setting fire safely?
I wish you all the best.
MG500 made in Greece
I was persuaded to take the last one of the exhibits.
Therefore, there are currently no exhibits in the warehouse.
I can't show you the actual product until it arrives in November.
There was a problem with the width of the bottom ash tray.
I purchased an extra ash pan for the next shipment, so I will send you a new one when it arrives!
Please wait for a while
The tiled roof of the shed is penetrated by aluminum-based silicon flashing.
Since it is an aluminum base, it can handle the unevenness of the tiled roof to some extent, but the width was not enough.
The missing part is added with the flushing sheet sold by the piece.
The butyl tape is closely attached to the back side, so it is convenient to stick anywhere.
But as far as I can see from the picture, the correct answer is to put it under the black sheet above.
Since it's a shed, the water from above doesn't flow except during a storm, so I don't think there's a problem...
What is that black sheet about 30cm from the wall?
This is also not our store, but it seems that a flushing sheet can be used as a substitute.
It may be a little lacking in support from the wall.
I think it would be better to put another wall bracket etc. to prevent left and right shaking.
Especially during a typhoon, it takes a lot of force, so I think it would be better to reinforce it.
It covers the sloped ceiling well.
Is this from our shop?
I do not know.
A heat shield is firmly attached to the single chimney.
It is now possible to reduce the 45 cm clearance to combustibles by half to 22.5 cm.
It seems that the main body is a little too close to the back, so we recommend that you measure the temperature of the inner surface of the furnace wall once.
Completion of construction does not mean completion.
After that, seeing the inside will lead to safety.
Be careful not to catch fire!
]]>For that reason, we will ask for advice on which one to ask.
Heat-resistant 600°C painted chimneys are mainly used for single chimneys and wood stove bodies.
This is light and rarely exceeds 300°C, so you can rest assured that the heat-resistant 600°C coating is safe.
Since the surface temperature of the double chimney does not normally exceed 100°C, there is no problem with the heat-resistant 300°C coating .
However, at present, double chimney products are mixed with two types of heat-resistant and temperature-resistant coating products.
In the future, we plan to unify our double chimneys with products that are heat-resistant to 300°C.
Therefore, the double chimney products with heat-resistant 600°C coating are set a little cheaper.
The appearance is slightly different.
Products with a heat-resistant 300°C coating are not glossy and feel a little rough to the touch.
And it is easily scratched when rubbed. (It will disappear when wiped with a waste cloth.)
Products with a heat-resistant coating of 600°C have a glossy and smooth feel.
And even if you rub it lightly, it will not remain after rubbing.
We hope that you will be able to purchase according to your preferences.
]]>Although it is quite far from here in Miyagi Prefecture, he understood the method of chimney construction through the exchange of photos on Line and completed the construction.
It seems that the house in this picture was made between her husband and work, except for the foundation.
Nice!
I've heard long ago that humans are the only animals that don't make their own homes, all other animals make their own.
After all, I feel that it would be good if there were a few people who went back to basics and built their own houses!
There are quite a few eaves because it is a snow country.
The double chimney is put out once, and then the roof is immediately penetrated.
Working hard even though the snow is dancing!
The CF07 wood stove was also purchased from the mountain chimney shop!
It seems that the wall furnace was also constructed by themselves!
"I was really impressed when I was able to install the wood stove. Thank you very much."
I was told to thank you, but here's how to say thank you!
I think that the impression was great because they did all the work themselves.
Be sure to clean the chimney every year to prevent fires.
]]>I had my daughter edit the video, transcribe it, and create a thumbnail, so the quality has been upgraded from the previous video!
In particular, I think that it will be very helpful because you can see the temperature inside the penetrating kit, the temperature behind the shield, the temperature of the outer wall, etc.
I would like to create videos little by little in the future, so please continue to support me in the future.
The video will be here .
]]>Concept of the air layer on the furnace wall and the distance from the stove
How safe is the distance from the wood stove to the furnace wall?
How to make a furnace wall
What should I use for the material?
Isn't there a lot of people who are worried about it?
Today, I would like to write about the idea of the position of the furnace wall and the wood stove, and the material.
This is the standard of the American National Fire Protection Association .
When installing chimneys, heaters, and boilers at the Fire Safety Association???
If you are interested, the original text is in English, but if you translate it from a site such as Google Translate, you may be able to read it.
To the last, this is a chart based on my interpretation and interpretation of American standards.
For that reason, I think it would be better to use it as a reference for construction and think about safety in your own way.
The installation of wood stoves is more common than in Japan, so I think it would be good to refer to countries like Japan where wood stoves are underdeveloped.
In Japan, the standards for installing chimneys are stipulated in the Building Standards Law.
However, since it is written based on a single chimney, it does not meet the criteria for using an insulated double chimney.
Still, in the case of a new building, it is necessary to apply for a building certification, and at that time, there is guidance from the local fire department, and they are told to follow it.
So be careful with new construction.
From here on, I will refer to articles on other English sites, and what I understand here, so please let me know if there are any misunderstandings.
First of all, the furnace wall that is generally easy to construct in DIY is a furnace wall made of calcine plate or iron plate with an air layer of 25 mm or more.
In addition to having an air layer of 25 mm or more, it is possible to reduce the safe distance from combustible materials to 1/3 for walls and 1/2 for ceilings by using appropriate materials and construction methods. It is
First of all, regarding the air layer, it is an absolute requirement to create an air flow inside the wall by opening the lower and upper parts of the furnace wall .
Heated air comes out from the top, so open the bottom to secure the air flow path.
And it must be a structure that cools the wall furnace with air.
In addition, if you open the top and both sides and create a structure that allows air to flow from the side to the whole, there is no problem even if the bottom is left open.
However, it may be necessary to devise a way to install the spacers so that the air can evenly circulate inside the wall and cool the wall.
The wall furnace is made of steel with a thickness of 0.6 mm or more, or cement-based noncombustible material with a thickness of 12.5 mm or more.
As incombustible materials that meet this American standard, it seems that 12mm silica gel board, 12mm gypsum board, etc. are easy to obtain.
In addition, even with silica slabs and plasterboards of 12 mm or less, it is considered that the conditions will be satisfied if the thickness is 12.5 mm or more after finishing with noncombustible bricks and tiles.
In other words, if you create the furnace wall with the above method, it is possible to shorten the distance from the wood stove to the wall and from the wood stove to the ceiling as follows.
A wood stove with a distance to the combustibles on the wall of, for example, 45 cm is as follows.
It is possible to install the wood stove and the wall as close as 15 cm, which is 3/1 of 45 cm.
For wood stoves with a 90 cm distance to combustibles on the ceiling:
It is possible to install the wood stove and the ceiling closer to 45 cm, which is 1/2 of 90 cm.
In the case of the ceiling, the heat rises and the air is trapped, so the standards are generally stricter than the walls.
Now consider the same furnace wall with 25mm rockwool or ceramic fiber insulation, or 9cm thick brickwork with no air layer or insulation.
This condition is worse than the air layer, and it is possible to shrink it to 1/2 for walls and 2/3 for ceilings.
Insulating materials and 90 mm thick bricks have no air convection, and even if noncombustible materials are present, heat is trapped in the furnace wall itself and the insulating material, making the conditions a little worse.
If the distance to the combustible material on the wall is 45 cm, it will be possible to install the wood stove and the wall closer to 22.5 cm, which is 1/2 of 45 cm.
If the distance to the combustible material on the ceiling is 90 cm, it is possible to install the wood stove and the ceiling closer to 60 cm, which is 2/3 of 90 cm.
We will also tell you how to think about the distance when installing a heat shield on a stove or a single chimney.
This is the idea of the distance when a semicircular heat shield is installed on the back and side of the wood stove body and on the chimney with a distance of 25 mm.
In this case, the distance to the wall can be halved, so if the distance is 45 cm, it will be 22.5 cm.
Also, if the ceiling is 90 cm, it will be 60 cm because it can be shortened by 1/3.
As for the distance from the stove body to the furnace wall when combining the furnace wall with this air layer and the heat shield of the stove body, it is not written, so I do not know.
It is possible to reduce the distance from the wood stove to the furnace wall when both are combined, but it is not possible to say clearly as a numerical value.
If you have any questions, please feel free to contact us from the inquiry column .
]]>In addition, Nozaki Sangyo Co., Ltd. is famous for those who install chimneys by DIY when it comes to cheap insulated double chimneys.
I tried to verify the compatibility and difference between chimneys of Yama no Entotsuya and chimneys of Homma Seisakusho and Nozaki Sangyo.
Left: Thermal insulation double chimney of Yamaentotsuya Straight pipe 0.5m ¥10,000 Effective length 457mm
Middle: Homma Seisakusho's double chimney with an air layer (the photo shows an unpainted product) Product name Double stainless steel semi-straight tube ¥17,100 Effective length: 353 mm
Right Insulated double chimney from Nozaki Sangyo Double insulated straight pipe 355 ¥8000 Effective length 355 mm
Yama no Entotsuya is TIG welded with heat insulating material, the single part is 0.5 mm thick SUS316, which is resistant to acidity even among stainless steel, and the double part is 0.5 mm thick SUS304.
In addition, the connection of the chimney of the single part becomes the reverse insertion type where the female mouth comes up. (No tar leakage)
This double chimney with insulation is instructed in Europe and the United States to keep a minimum distance of 5 cm from combustible materials. (European certified product)
Homma Seisakusho uses 0.4mm thick SUS340 stainless steel, which is relatively cheap for both single and double layers, to insulate the air layer without insulation in the seam fold chimney.
In addition, the connection of the chimney of the single part will be a positive insertion type where the male pipe comes up. (There is a possibility of tar leakage.)
Insulation by this air layer is instructed in Europe and the United States to keep a minimum distance of 15 cm from combustible materials.
Nozaki Sangyo is a seam fold chimney with insulation material. Other parts are the same as Honma Manufacturing.
However, since it contains heat insulating material, it may be possible to keep it at least 5 cm away from combustibles, but it is unknown because it is a seam-folded chimney.
Also, it seems that the seam fold chimney will not pass the European certification.
The bottom is Nozaki Sangyo and the top is Homma Seisakusho's goby folded chimney.
Since both chimneys are the same seam fold chimney, the single chimney part is compatible with the correct insertion type.
There is an inquiry about the compatibility of the above-mentioned seam folded chimney and Yamano Entotsuya's welded pipe insulation double chimney.
The answer is no compatibility.
The double pipe part is the same reverse insertion type, and the rain that comes on the male port does not enter inside, so it is possible to connect somehow.
However, since the single part is a reverse insertion type and a normal insertion type, connection is not possible.
If you ask me if it is absolutely impossible, I would say that it is possible if you use a pliers-like tool called a five-blade crimper .
However, please understand that it is impossible because it will be very clumsy and the length of the insertion is greatly different.
We rent and sell these tools , so please use them if necessary.
Regarding the single chimney, it is impossible to connect the seam folded chimney and the double chimney of Yamaentotsuya as it is, but there are two ways to connect it.
Purchase the 152mm-152mm adapter sold at Yama no Entotsuya .
Alternatively, it is possible to connect by using the above five blade crimper to apply waves to either chimney and squeeze it.
Regarding the penetrating kit , it is possible to use both the seam folded chimney and the insulated double chimney of Yama no Entotsuya.
However, the support base cannot be connected to the seam folding chimney.
If there is anything you do not understand, please feel free to ask a question from the inquiry column .
You can also ask questions on LINE from there.
Nozaki Sangyo Single Jujikyoku
The lid could not be fixed with screws, etc., so I was worried that it might come off.
Because it is made of stainless steel SUS430 0.4 mm, it is thin and flimsy and easily collapses into an oval shape.
The price was 6000 yen including tax.
Yamano Entotsuya's single tube is made of SUS304 with a thickness of 0.7 mm, so it is quite solid compared to that.
This is a single chimney with a T-tube cap that is sold at Yama Entotsuya. 6000 yen including tax.
]]>
Is it possible to join with other companies' chimneys that are currently frequently asked questions?
That's what it means.
The first and foremost thing is to buy a chimney from our shop and if it doesn't fit, you can return it.
Basically, we accept returns within 30 days without any reason, so please order a shorter chimney and check if it can be connected to your existing chimney.
There is a round trip shipping fee, but it is definitely worth trying.
If the male is too big to fit in, there is a tool called a five blade crimper that waves the chimney to narrow the diameter, so you can use it to connect.
This product is also available for rent at our shop, so if you need it, please see the product list.
Another method is to measure the circumference with a cloth tape measure to determine the diameter.
Since I planned the outer circumference of the single chimney before, I will describe it in the hope that it will be helpful.
I measured the actual size of the outer circumference of the single tube at three points.
Male 476 476 475
Female 483 483 482
The diameter when male 476 female 483 mm is
Male OD diameter 151.59
Female outer diameter 153.82
The inner diameter of the knife cannot be measured, but the thickness of the stainless steel plate is 0.7 mm for a single pipe, so the inner diameter of the knife will be 152.42 if subtracted 1.4 mm.
From the above, the diameter is calculated as follows.
Outer diameter of male pipe 151.59mm
Female tube inner diameter 152.42mm
As for the diameter, the chimney is distorted, so the complete diameter cannot be obtained, so it was necessary to calculate it.
Please point out any mistakes.
]]>This is chimney shop in the mountains.
I received a photo of the installation from a customer today, so I would like to introduce it.
Of course I have permission to post.
And of course, if it is difficult to post it, I will delete it.
It was constructed by MECHAWORLD Co., Ltd.
It was also said that this place would like to be a cafe in the future.
By the way, this purchase is for the chimney only.
As for the wood stove, it seems that he bought a wood stove with an oven on Yahoo! Shopping.
It was said to be good for baking pizza!
I've seen this stove too.
They probably sell a lot.
And the outside was constructed like this.
It seems that you have purchased separately a reinforced spectacle stone from Honma Seisakusho.
I forgot to ask, so this is my guess based on the photo.
Unfortunately, we do not sell it at our store.
As for the construction, it is a complete amateur, but it is very well constructed! ! !
I would be very happy if you could send me a photo.
Once again , thank you MECHAWORLD Co., Ltd.
By the way, there was a request to replace the chimney in the middle of construction.
I purchased four 1M insulated double chimneys and shipped them.
However, when all the chimneys are installed, the chimney becomes longer, and I am worried that it will break in strong winds.
At Yama no Entotsuya, you can return or exchange unused items within 30 days.
After that, we will accept returns, so please contact us.
If you have leftover chimneys that you don't need even if you have them at hand, or if you are not satisfied with them, we will accept returns, so please feel free to contact us.
These products are carefully checked for scratches, etc., and then sold at outlet stores at bargain prices.
see you soon
]]>I have had some doubts for some time.
The reason is that I can't find anything called "Meganeishi" even if I search for it on English websites.
There is a penetrating kit that has the same shape as the penetrating kit sold at the mountain chimney shop instead of the spectacle stone.
The photo below is a penetrating kit that is on sale at Yama no Entotsuya.
It is sold under the name Wall Thimble on Amazon in the United States, so please check it out if you are interested.
Also, if you know something similar to the Japanese glasses stone, please let me know.
Maybe my search method is bad.
So if you don't have a glasses stone, you can't penetrate the wall? ? ? I don't think so.
If you look at the manuals and construction examples issued by European and American manufacturers, there is no mention of spectacle stones.
It only says to use Wall Thimble as above to go through the wall.
And this Wall Thimble has 5cm air space around it.
Class A insulated double chimneys are considered safe if they are kept at least 5 centimeters away from combustible materials.
The insulated double chimneys sold at Yamano Entotsuya are made in the same factory on the same line and with the same manufacturing method that have cleared the same Class A standards.
There are no regulations regarding chimneys in Japan, so we do not import chimneys that have been tested to see if they meet the standards.
But the quality seems to be the same.
Also, if you look into the Building Standards Act and Fire Service Act, there are certainly regulations regarding chimney penetration through the wall.
Roughly speaking, 15 cm from the chimney should be made of incombustible materials such as spectacle stones.
So from here on out it's just my opinion .
It is not in line with the Building Standards Act, but I think it will be the basis of the way of thinking.
If you are going to build it yourself, please think about a safe construction method for yourself by referring to this.
When penetrating a wall with an insulated double chimney with an outer diameter of 200 mm, it is necessary to make a hole of at least 300 mm x 300 mm or a diameter of 300 mm and insert the insulated double chimney there.
Since this is just a minimum standard, I think there is no harm in taking additional safety measures such as making the area around this 5cm frame with silica gel.
By the way, please pay attention to the opening size when penetrating the roof.
300 mm laterally to the slope of the roof is fine, but be careful about the vertical direction.
While the chimney is installed vertically, the sheathing boards and rafters of the roof are sloped.
Therefore, it is necessary to widen the distance as the gradient increases.
Actually, it seems that it will be 320 mm or 350 mm or such a number.
The steeper the slope, the larger the dimension.
Please be a little careful there.
In fact, I think I'll know if I turn the roof and check it after the chimney construction.
Let's go back to Meganeishi.
Of course, if you are worried about it, it is good to put something called a spectacle stone.
However, if you follow the Western way of thinking, basically you don't need a spectacle stone for the penetrating part of the wall.
I think you can use a penetration kit .
So where did the realization of the need for a spectacle stone come from?
I have a memory that the wood-burning stove that appears in the drama from the northern country had something like a stone stuck in it...
However, come to think of it, traditional Japanese stoves such as daruma style stoves and clock style stoves were constructed with a single chimney.
Even now, when I go to the countryside, I often see old private houses with single chimneys and white smoke.
If you are working with a single chimney, the distance from combustibles should be at least 45 cm as explained in the previous blog.
For that reason, it is speculated that something called spectacle stone was placed in the wall to reduce the distance.
Of course, this is all speculation on my part, so I can't say for sure.
But do you need a spectacle stone?
If you ask me, I would like to say that it is not absolutely necessary.
Glasses stones are not cheap either.
However, by inserting a spectacle stone, you can be sure to keep a distance of 5 cm or more from combustibles.
Therefore, if you feel safe to put it in, I think you should use it.
It is safe and secure if you take sufficient measures for further safety.
But! ! !
If you put a combustible material such as plywood on top of the Megane Stone, it will be completely meaningless! ! !
Make sure that the insulated double chimney is at least 5 centimeters vertically, horizontally, and diagonally away from combustibles!
If you follow these rules, it's just a matter of whether you're good at DIY construction or not.
Of course, the issue of chimney sagging is separate.
The sagging will prevent a safe distance of at least 5 cm from combustible materials.
Also, if the chimney is not cleaned once a year, soot and tar build up, which can ignite a chimney fire.
Please note that as common sense!
All construction workers should acquire knowledge of construction methods to prevent falls from high places and fires.
see you soon
]]>Actually, it's easiest to understand if I explain it with an illustration, but I don't have the ability to draw diagrams using a computer, so...
I will look into it soon.
Basically, it is regulated in the United States and Europe that the distance from the insulated double chimney to combustibles should be at least 5 cm.
This combustible material literally burns.
In other words, in general, even if it is a gypsum board, there is a possibility that it will burn even if the wall is covered with vinyl cloth from above, and even if the vinyl cloth is certified not to be subject to the interior decoration restrictions of the Building Standards Law. It is safer to leave it on.
Also, the wood and plywood used as the base when penetrating the wall.
Plywood and rubber asphalt roofing when penetrating ceilings and roofs, etc.
If you throw it into a fire, it will burn.
Please keep a distance of at least 5 cm from these objects.
and regulated in the United States.
The surface temperature of an insulated double chimney can rise to around 70 degrees when it is high.
Therefore, keep a minimum distance of 5 cm from the surface of the double chimney.
What about a single chimney or single chimney?
In this case, it is necessary to keep a distance of 45 cm from the combustible material on the wall.
In the case of a single chimney, when the surface temperature of the chimney is high, it may rise to nearly 300 degrees.
Therefore, if exposed to this heat for a long time , there is a danger of charring combustible materials within 45 cm and igniting.
How about putting a heat shield called a heat shield on the back of the chimney?
In this case, it is written that it is possible to reduce the distance to the combustible material on the wall to 1/2.
In other words, the distance from the chimney to combustibles can be reduced from 45 cm to 22.5 cm, which is half of that.
The most important thing to keep in mind when using an insulated double chimney is to keep a distance of at least 5 cm from combustibles.
When penetrating a wall or roof, it may be safer to cover combustible materials with a fire-resistant material such as silica gel in anticipation of safety.
Discoloration and charring of visible parts can be noticed if you look at them, so there is almost no danger.
The most dangerous places are inside the walls and ceilings, especially in areas where the air is sealed and the temperature rises rapidly.
We strongly recommend that you open such areas regularly and check for discoloration!
Everyone, please be careful when constructing.
]]>As you can see in the Amazon review, it is true that using a glass cleaner for wood stoves removes dirt well.
In my home, I heard from someone that if the ash from the burnt residue is wetted with water and rubbed, it will come off, so I've been practicing it for a long time.
Certainly light stains were removed with it.
But my house was a mess, and when I tried to remove two months worth of dirt all at once, it was really a big deal.
I removed the door and physically scraped it off with a steel scrubber.
As you can see, it's almost impossible to enjoy fire.
So this time I tried using the imported PERKINS Perkins glass cleaner.
Is it for gas? I thought, but it was written as a wood stove further below!
And how to use it, like the picture below, put a small amount on a newspaper or paper towel and draw a circle on a glass that is not hot.
It was written so, but I ignored it and rubbed it on the side.
The lower half had a bit of stubborn crumbs stuck to it.
Apply 3 more times.
Then, oh my God!
Stubborn dirt will come off.
Even so, the lower half has some fine scratches, probably because I wiped it with a steel scrubber before, and it looks like frosted glass, so it's not completely clean.
Bad example!
With this, my family is finally able to enjoy a life with a small fire.
After all, it's great to see the fire!
This product is sold as a related product for wood stoves.
It will be a product that can be shipped for 500 yen.
]]>Have you ever searched for chimneys on Amazon, etc.?
I have! ! !
However, I was fed up with the high price of chimney stoves in Japan, so I started a stove shop called Yamano Chimney Stove, so it is natural to check the prices in other countries.
It's a chimney price, but it's very cheap!
I recommend everyone to check it out once.
The search keyword is double wall chimney pipe 6 inch.
It is a product with a double chimney of 150 mm.
Made in the USA, made in China and various things are hits.
And the price is about 120 dollars for a 1 meter straight chimney, so if you convert it to Japanese yen, it will start at 13,000 yen.
Then, why is it disguised as a price of 30,000 yen or more in Japan?
Of course, there are also domestic chimneys, so it's natural that it's expensive? I think there are also products that can be said.
Land is expensive in Japan, so warehouse fees are high.
Domestic shipping charges for large cargo such as containers are high.
It is expensive considering the inventory risk because it does not sell so much.
I think that it can be raised, but I think that the price of 3 times or more is abnormal.
Of course, if I say something like this, I will get the antipathy of the town's stove shop, but...
Of course, if you prefer Japanese products, even if they are expensive, the quality is definitely good, so I think you should buy them.
However, Chinese chimneys are similarly expensive.
But according to many stove makers,
The four seasons in Japan are harsh
there is a typhoon
Hot and humid with lots of rain
Cheap chimneys pose a flue fire hazard
Rainwater enters inside due to capillary action
If you burn down your precious house, even if you can buy it cheaply, it will end up being an expensive purchase.
For various reasons, I'm going to talk about Japan's unique standards for chimneys.
I suspect it's a little different.
The chimneys that Yama no Entotsuya will sell are socketed in a traditional way.
However, it is not at all inferior in terms of technology and usage.
As a big difference, the latest type is called a twist lock, which is inserted and twisted to fix it.
In addition, since the ceramic fiber insulation is sealed, it can be said that there is no water intrusion into the ceramic fiber.
However, regarding the socket connection, the length of the connection port is 5 cm, so there is almost no rainwater intrusion.
As you can see from the roof, the slope of the roof is about 3.5 inches.
Chimney slopes, on the other hand, are vertical or 60° curved slopes.
It is quite steep.
At such a slope, even though it is caused by capillary action, it is impossible for rainwater to enter the insulation material inside the chimney as water flows upwards by 5 centimeters at the joint.
What would be the problem if the stove shop in the town got in as they say?
Rain is probably already getting in through the chimney cap.
Ceramic fiber insulation is inorganic and does not rot.
Also, when heated by using a wood stove, such moisture quickly evaporates and disappears.
So it's not a problem, is it?
I think.
Wouldn't you like to sell it at a more affordable price than that?
If you don't have it, I will sell it!
I'm sorry to keep you waiting, but production at the Chinese factory will be completed in mid-November.
After that, all you have to do is load it in a container.
It will be available for sale soon, so please wait for a while.
It's a little higher than Amazon's price in the US,
Warehouse fee
Domestic shipping charges for containers
low sales volume
Considering such things, it has become the current price.
Still, I would like to deliver high-quality products with low profit and high sales to everyone, so please support me.
I recently saw on YouTube that business is an exchange of value.
That makes sense.
Give something of value, a product, and receive money worth it.
It's an exchange of value!
I think it would be great if we could create a situation where we can make each other happy through the sale of chimneys.
If you are in the Kansai area, we will also accept construction, so please contact us if you are interested.
]]>We have been waiting for a long time, but the insulated double chimney is scheduled to arrive at "Yama Entotsuya" in early December!
This product is not purchased through a wholesaler, etc., but is ordered directly from a factory in China, so it can be sold at a low price.
Even though it is made in China, this chimney was produced in a factory that is exported to Europe and has received strict European CE certification, so there is no doubt about its safety.
In addition, we asked a Japanese person to conduct the final inspection, so there is no problem with the quality.
A double chimney with an inner diameter of 150 mm and an outer diameter of 200 mm is filled with ceramic fiber insulation, so there is no risk of burns even if you touch the outside during use.
The inner tube is made of SUS316, that is, stainless steel.
Since the inner tube is exposed to acids such as creosote generated during combustion, SUS316, which has excellent acid resistance, is used.
The external pipe is made of SUS304, which is resistant to rust.
The product has a thickness of 0.5 mm both inside and outside.
All the chimneys handled by "Yama Entotsuya" are seamless welded pipes, so they are stronger than cheaper seam pressed pipes, and there is no need to worry about rainwater entering.
In addition, we have almost all the materials necessary for installing a chimney for a wood stove, such as a welded single chimney (SUS304 0.7 mm thick), roof flashing, storm collar, chimney top, chimney support for wall exposure, etc.
As soon as it arrives, it will be uploaded to the product page, so if you are interested, please register your email and we will contact you as soon as it arrives.
Installation work is also possible in the Kansai area, so please feel free to contact us if you are interested.
]]>In that state, it is terribly not recommended to hold the double chimney that weighs 7 kg and work with both hands separated.
I don't think I can do it because I'm afraid even if I challenge.
Next is a pattern that penetrates the ceiling and puts out the chimney from the roof.
This is sure to leak if you make a mistake in stopping the rain even a little.
In particular, the tiles have large gaps and are difficult to clean up after the chimney penetrates, so I think it is safer for amateurs not to touch.
The simplest thing is the single roof that is common in American houses.
However, single roofs are not so popular here, so it is not as easy as in the United States.
In the United States, many chimneys are constructed by DIY, not only because of the culture of DIY, but also because it is easy to construct chimneys with single roofs.
If it is a single roof, the construction of the chimney is of course easy at the time of new construction, and the construction later is not so difficult.
Another simple reason is that rubber flushing such as EPDM and silicon is used.
Silicon flushing is said to last about 20 years, but the firewood stove that I personally imported and installed at my parents' home was also made of silicon, but even after 20 years, I haven't seen any cracks.
Moreover, I was very surprised that it did not deteriorate even though it was facing south and was exposed to ultraviolet rays.
Going back to the topic, many of the houses in town, such as ready-made houses in Japan, have colored vest roofs.
Therefore, it is not as soft and flexible as a single roof, so drilling is a little difficult and may break if done poorly.
Color vests are sometimes sold individually at home centers, so if you pick them up and take a look, you'll understand that they're easy to break.
However, if you use an electric tool such as a grinder, you can drill holes without breaking.
Even if you don't use silicon flashing, if the roof is made of Color Best, it is possible to penetrate the chimney roof with stainless steel flashing sold at Yama Entotsuya.
Please look forward to making and uploading a YouTube video of the construction method in the near future.
No matter which stove shop you ask, they probably won't take it seriously saying that the chimney is more expensive than the stove.
So why is it so expensive?
According to the stove maker, Japanese chimneys are made for Japan's climate (high temperature, high humidity and lots of rain), so it's only natural that they're expensive.
Also, Japanese chimneys are of good quality, so it is natural that they are expensive as a result.
You will see answers like this.
I think it's probably half true and half sales pitch.
Does Japan need a special chimney because it rains more than the US and Europe?
That's not true.
There are certainly typhoons, but America also has hurricanes.
It's true that it rains a lot, but America and Europe also have more rain than Japan in some areas.
Where does the price difference come from?
In the United States and Europe, wood stoves can usually be purchased at home centers, and many people install them DIY.
Even if you search on Amazon, double chimneys are listed at less than half the price in Japan.
Wood burning stoves are also available in a wide variety of prices.
Are those chimneys of bad quality?
That's not true.
Unlike Japan, there are soot and smoke regulations set by the EPA in the United States and CE in Europe, and it is necessary to clear combustion tests for chimneys, but only those that meet the standards are allowed to be sold.
Looking at the standards, the seam fold chimney does not meet the standards, so it is impossible to sell it for indoor use in the United States and Europe.
These strict standards apply not only to chimneys, but also to household wood stoves.
On the other hand, anything is possible in Japan, so home centers sell very cheap wood stoves.
The products handled by Yamano Entotsuya meet the strict European CE standards, so you can rest assured that the quality is good.
I think the difference in price is the result of the large difference in sales volume and the brand strategy in Japan.
The wood stove and chimney are luxury items! If you want to buy it, please consider at least 1 million yen! It seems that everyone in the firewood stove shop in the street is said.
It's true that the way an expensive wood-burning stove burns can be quite enchanting.
But do you really need to ask that much for a chimney?
If it's not an expensive chimney, will it cause a fire?
Since it is a double chimney with insulation material, it will not cause a fire if the construction method is correct.
Of course, the chimneys sold at the mountain chimney shop are socket-connected, so the connection method may be different, but there is no rain intrusion.
However, the appearance of the joint part is a little different from the high-end twist lock.
Isn't it silly to pay hundreds of thousands of yen just for the difference in appearance of joints?
I think.
Therefore, Yama Entotsuya offers chimney stoves and wood stoves at reasonable prices, and we would like to support a lifestyle where you can easily enjoy the wood stove life.
In addition, we accept returns of chimneys for home use within 60 days from the arrival of the product.
Chimneys left over from construction, chimneys that were not used due to a change in the construction route, or chimneys that were purchased more than expected can be returned as long as they have not been set on fire, so please feel free to use them.
We will resell the returned chimneys at the outlet price, so future buyers will be happy, so we are happy to accept returns!
]]>through the roof?
Which one is the best?
There is no correct answer, but each has advantages and disadvantages.
Let's start with wall penetration
merit
Construction is easy if you prepare scaffolding → Easy to do DIY construction
low construction cost
Less damage to buildings
Even if the construction is bad, there is almost no worry about rain leakage
Demerit
Poor draft (smoke removal) due to horizontal pulling
Double chimneys with L pipes, T pipe caps, support bases, etc. are often used, so material costs are high.
high heat loss
It is difficult to clean the chimney cap as it protrudes outside the roof
not aesthetically clean
On the other hand, the roof penetration
merit
Since the chimney is straight, the draft (smoke removal) is good.
Since the chimney passes through the interior, more heat is released into the interior, resulting in less heat loss.
The indoor part can also be made into a single chimney pipe to some extent, so the material cost is reduced.
Penetrating the room on the second floor will also warm the room
Clean appearance
Often easy to clean from the top of the roof (except on steeply pitched roofs)
Demerit
If the construction is bad, there is a risk of rain leakage → DIY construction is difficult
The existence of the chimney becomes an obstacle when penetrating the room on the second floor.
high construction cost
When cleaning from the wood stove side, curing is necessary so that soot does not scatter indoors
Both have their pros and cons.
I think it would be nice if you could think about installing a chimney in a way that suits you.
Even if the method of installing a wood stove is different, there is no difference in the fact that a life with a fire will enrich our daily life.
Yama no Entotsuya is an online shop, and nearly 90% of customers ask for DIY installation or installation by a carpenter, but it is also possible to install a wood stove.
The remaining 10% are purchased by chimney construction shops and construction shops that do not have conventional shops.
At Yamano Entotsuya, we will visit you for the installation together with an experienced carpenter.
We also support DIY installations.
If you have any questions or do not understand, please feel free to contact us by email or LINE .
By the way, the chimney of our stove was of course DIY.
At first it was a wall of a single chimney.
The horizontal pull was about 2m and the smoke pull was very bad.
I quit after one season.
Next, I made a double chimney using a plated spiral duct and made a double chimney with a roof.
And in the 3rd year, it broke from a typhoon where it rusted beautifully.
The galvanization melted from the heat, making it the same as a normal iron chimney, and the soot was acidic, so rust progressed faster than I expected.
The third one was a stainless steel welded single chimney made by Homma Seisakusho.
I've been using this one without any problems.
I think I used it for 4-5 years.
And at the end, I replaced it with an insulated double chimney on sale at the mountain chimney shop!
It was a long way to go until I found something good because the cost was high because I went to various places.
Also thank you.
