Is it possible to install a chimney DIY?



In short, it's case by case.



The double chimneys sold at Yamanoentotsuya are filled with insulation.



So if you follow the basics, you don't have to worry about fires.



The problem is that people who don't clean their chimneys, or who don't follow the basics, such as people who force their chimneys through walls with a single chimney, can cause fires.



First of all, I would like to talk about the case where DIY installation is possible.




When a stove is installed along the outer wall and a chimney is installed through the outer wall



In this case, there is no need to worry about rain leakage, so if you can prepare scaffolding, I think it will not be so difficult.



First of all, you need to open a hole through the siding and control panel of the outer wall, and the gypsum board of the inner wall.



This takes courage, determination and tools!



So if even one of them is not enough, we recommend that you request installation.



It takes a lot of courage for a non-professional amateur to drill a hole in a shiny new house.



Once the hole is opened, all you have to do is install the chimney using the wall/floor penetration kit and cover it with caulking to keep the rain out.



All you have to do is support the chimney from the wall with a wall support and set it up.



If you don't have scaffolding, you can work with a double ladder, but if it's a two-story building, it's over 7 meters, so it's very dangerous.

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.
