Introduction: Flexible Chimney Liner Installation

Installing a flexible chimney liner is something most handy people can do themselves. Follow this guide and you will be able to handle the project.

You will need the following:

  • flexible chimney liner
  • work gloves
  • caulk/caulk gun
  • snips or hacksaw
  • tape measure
  • knife
  • screw driver
  • a drill might be nice, but not necessary

Step 1: Remove All Chimney Liner Parts From Packaging

Caution: Metal edges can be sharp, make sure to wear protective gloves when handling the liner and liner components.

Also make sure your chimney has been cleared of all debris before installing the liner.

Step 2: Unroll Chimney Liner Coil

It usually helps to have a second person to unroll the liner. While one person is holding one end, the other person unrolls the chimney liner keeping firm pressure down to get it to lay flat. After you unroll the chimney liner you may need to work some areas to get it as straight as you like. Be patient and work the liner in the needed areas.

Note: If you are not installing your liner with high temp insulation blanket you can leave the liner coiled and uncoil it as you push it down the chimney. For more information about insulating a chimney liner visit this site.

Step 3: Attach Bottom Termination

Next you will attach a tee or stove connector to your liner. The bottom termination will include a hose clamp that tightens to the chimney liner.

For determining what type of bottom termination your chimney liner installation will require visit Chimney Liner Depot. They can help you with your installation type.

Step 4: Insulate the Chimney Liner

Unroll your chimney liner insulation next to your liner. Lay the liner in the middle of the blanket. Once you have everything centered spray the liner and insulation side of the blanket with spray glue. This will help keep the blanket in place while you tape up the seam.

Pull the insulation tight around the chimney liner and lay short pieces of tape across to the seam to hold it in place. Once you get that done the entire length of the chimney liner, lay one continuous length of tape down the seam of the blanket.

Step 5: Install Wire Mesh

The wire mesh as part of the chimney liner insulation kit is design to help protect the insulation blanket from being torn as you push it down the chimney.

This part will take some time as you have to pull the mesh over the liner, kind of like you are putting a giant sock on the chimney liner. It helps by putting a ball on the side you are putting the mesh on first. This deflects it away from any hard edges and keeps it from getting caught up on the end.

Step 6: Installing a Tee

If you are installing the chimney liner for a fireplace insert then you will not need to worry about this step.

You need to get the vertical part of the tee to go through the hose clamp on the horizontal part of the tee. It's best to have an assistant for this part. They can guide the vertical part of the tee through the tee snout as you push the liner down from the roof.

Once the liner is positioned correctly, tighten the hose clamp on the tee snout to complete the bottom termination.

Step 7: Install Top Plate and Rain Cap

Once the liner is connected at the bottom you can trim the liner at the top of the chimney. Make it flush with the top of the top plate collar.

Next lay a bead of caulk on the chimney crown and lay the top plate on top. Tighten the hose clamp in the top plate collar to secure it to the liner.

Next attach the rain cap to the top plate and tighten the hose clamp.

Good job! You just installed a chimney liner.
