I have been searching for a suitable chimney for over a year now. If you have never looked into the price of good double wall insulated chimney, you are in for a shock. It runs about $125 a foot! I had 8 feet of it but was missing one T- section. Of course the company has updated their line, which as far as I can tell means they changed the coupling between sections just enough that the new and old systems are not compatible. I couldn't buy a new T, and could not find a used one anywhere. Last week I finally found a good deal on a used setup that had almost everything I needed. I was hoping that I could make a couple of pieces of my old one work with the new system but unfortunately no matter how many times I tried, it just wouldn't work. In the end I had to buy a one foot section of new pipe to make it through the wall.
After much time spent figuring out the best place for the chimney to exit while maintaining the proper clearances, I set up my router with a jig to cut a clean circular hole through the siding. Once the siding was cut I finished off the sheathing with a jig saw since it will not show.
Next the thimble was installed and the first section of pipe went through the wall, followed by the T. I fabricated a brace to stabilize the next length of chimney and then installed that with the cap.
Hooking things up inside involved nothing more than plugging the sections of pipe together. After worrying about this for so long, it was nice that it all went so smoothly.
It was a warm day today but I had to light a little fire to see how it all worked anyway. I don't have any heat shields installed yet so I just built a little fire to test it out. It had a great draft and I was able to make the fire respond instantly by adjusting the air inlet. Seems good! I still have a lot of details to finish before I can call in done, but it is a major step in the right direction! It is nice to feel somewhat prepared for the cold weather this year. Now I need windows, two sections of wall and some insulation.
