Robert explains how to install Chimney Liner.

Installing a stainless steel chimney liner is an easy and economical way to repair a deteriorated, unsafe, or inefficient chimney flue. You will be able to install a chimney liner after reading this and watching the video. You can do the job with common household tools. A chimney liner should be installed to reduce the chance of a carbon monoxide leak, chimney fire, and creosote buildup. Chimney liners also improve the energy efficiency of the appliance and makes fireplace maintenance easier.

First, determine the appropriate size chimney liner for your specific setup. The chimney liner diameter size you will need will be the same size of the exhaust outlet on the appliance. The chimney liner length you will need will equal the height of the chimney. we recommend ordering slightly over that amount to give room for error.

Only a few tools are needed for a successful chimney liner installation. You'll need a tin snips (or a sawzall or hacksaw), drill and bit, flat head screw driver, caulk gun, work gloves, and safety glasses.

Every basic chimney liner kit is going to come with four main components: the stainless steel chimney liner, connector (either a Tee connector or a Stove Top connector), top plate, and rain cap. This video shows a basic stove top installation.The top plate is going to be the main variable for a chimney liner kit.

Start by using your knife and remove the plastic wrap that the liner is coiled in. Once you have the liner out, start to straighten the liner. Make sure to do this on the grass or a soft surface so you don't puncture it. Straighten the liner out as best as you can. It does not need to be perfect as you will have to do some manipulation to get it down the chimney.

After installing the insulation you will need to get the liner to the top of the chimney. Proceed to lower the liner down the chimney until you reach the damper or smoke shelf. You will need to do some adjustments when you get back inside to get it through this.

Twisting the flexible liner will help you install the liner if you are getting caught or hung up on the chimney walls.

Now you will need to head into the house to finish connecting the appliance.

Once the stove connection has been installed correctly, it is time to connect the stove pipe to the stove. Most stove pipe comes with three screws per connection point. Use your drill and drive the screws into the horizontal part of the tee and through the exhaust collar of the stove. using furnace cement to secure and stop any leaks.

Once the chimney liner is all the way down the flue to the point of the appliance, the next step is to connect the top plate to the top of the chimney. The main function for a top plate is to seal the existing flue from rain, wind and critters from entering the chimney. Start by using your caulk gun and a tube of weather resistant high-temp silicone to run a bead of silicone along the top edge of the clay flue.

Next, thread the chimney liner through the round collar of the top plate so that the top plate is sitting on the top edge of the clay flue.

When you have successfully installed the top plate, the next step is to cut the excess liner flush with the top of the collar of the top plate. Your sawzall or hacksaw will work just fine.

The next step is to secure the rain cap to the top plate. The Cap will just slide over and then tighten the clamp.

Congratulations, you have successfully installed a stainless steel, flexible chimney liner!

Dude installed that liner like a champ. Stop being haters. People are just mad cause this guy is showing us how to do this job ourselves instead of paying some chimney guy that wants to charge us $1000-3000 dollars to install something that's very do able. Of course he missed some things but he has demonstrated the main concept for the most part. Strap your selves down for safety and take some of the comments on here that others have said and do this yourselves people.

Thanks for the video. I am a retired havac/sheetmetal mechanic. Installed my share of stoves and sheet metal to masonry connections. Using lead or other soft metal screw inserts when fastening the cap to the terracotta will enable you to fasten the screws securely without "breaking" the terracotta. In this case the screw holes need to be slightly oversized. Great job and thank you for taking the time to share. Gotta love youtube!

[davidsanford]

well I know more about this project than I did before watching the lot of negativity but, I don't see anyone pointing to better resources. Thanks for your video

4 in grinder works great for cutting liner. Good video.

[harmonicresonanceproject]

Excellent video. I learned, finally, that there is no dropping that flue liner down 'yourself'! Two man job for sure.

[zack]

I usually use a grinder with a cutting will make easy for of the liner

[samella]

Would have liked to see how you covered the liner with the insulation and mesh.  Thanks for posting.

[SeeMooreVids]

QUESTION: Did you remove the fireplace damper, breaking out or removing damper flap, and how was the space in firebox sealed or not sealed around the new liner? Thanks for great video..👍

[patcornwell]

How did you get by the smoke shelf or do you brake it out ?

[MapleGroveProductions]

Thanks, guys! Nice work! Reminded me of the good old days working my Dad on home renos. 🙂 Cheers!

Heats my whole downstairs and my upstairs hallway with no problem. Thermostat works great...beautiful flame. Quiet and easy to install

[richardvelez]

I normally don't leave comments but this video is genius an actual install with hiccups and their fixes. Tip my hat to you guys 🤠

[barbaralupe]

thanks for showing! it would have been helpful to watch how you dealt w inserting the firebox

[malaquias]

I liked it but would install the connector between the fireplace and the tube the other way around. That metal fastener seems to be better off when tightened against metal. Also, that way you would make sure to capture all the smoke from the fireplace and insert all of it into the tube, the narrow closer the smoke and the larger opening closer to the tubing.

wonderful install liner video. *** Q: What brand is the wood stove with the 45 degree exhuast on the back side of the stove???

[carle]

Wow, very nicely done. The only thing I would worry is rolling down the roof there, though it does not look that steep.

[JW-hhqg]

having installed hundreds of these correctly, watching this really stresses me out haha. ;)

MUCH better than some installs I've seen though!

[tomleonard]

To cut your liner you might also try taking an old wood cutting circular saw blade and flipping it around backward and using your circular saw. That's how I cut barn metal. It takes it some time to start cutting but once it starts it's much quicker and easier than tin snips.

How’s the power outlet installed. Good video

[jackle]

Well, if my chimney is 6.25" wide inside diameter I'm guessing a pipe with insulation probably will not even fit down it will it?
