How to Install a Chimney Liner

Step-by-Step Guide

1. 1

   Step 1: Inspect the chimney.

   Use a light source on a string (or an inspection camera if you have one)to look for bends, or restrictions that could interfere with pulling the liner through.
2. 2

   Step 2: Determine the correct diameter of the liner.

   If for a wood stove/insert, consult the owners manual for proper sizing.
   
   For an open fireplace, look for a chart or calculator online. , To ensure you have enough liner, add an additional 12 inches (30.5 cm). , The liner should come with a kit that contains all the pieces needed. , Hook up the bottom connector to the bottom of the liner.
   
   Fasten a hose clamp to the connection with a wrench.
   
   Don't fasten it too tightly. , If there is more than 2" clearance between the liner and chimney wall on all sides, the blanket liner is best. , Add 1 inch (2.5 cm) to be sure you have enough.
   
   The overlap can be trimmed later if necessary. ,, Center the liner on top, and wrap it with the installation.
   
   As you pull the chimney liner insulation closed, leave a minimum of 1 inch (2.5 cm) overlap so that you can secure it with tape. , In 12 inch (30.5 cm) increments, seal the seam with foil tape.
   
   Repeat this process until you have completely covered the liner with insulation. ,,, From the other end, pull the mesh taut over the liner.
   
   Fasten the remaining host clamps on that end, and make sure to keep the wire meshing tight.
   
   Use your tin snips to remove any mesh that overhangs the liner. , Specific instructions on how to pull the liner through the chimney may vary slightly from the guidance here.
   
   When in doubt, always follow the manufacturer's instructions.
   
   The most difficult point is typically the damper in the top of the fireplace. ,, Have a second person feed you the liner from ground level, and return to the bottom of the chimney to assist you in the installation process. ,, Slowly guide the liner downward.
   
   The second person should aid in this process by gently pulling the rope to help the liner's descent. , If necessary, cut the top of the liner with your tin snips to equal 4 inches (10.2 cm) higher than the chimney crown. , Seal the chimney crown with silicone caulking.
   
   Place the chimney's top plate over the installed liner, and press it firmly into the caulk to seal it. , Use the pre-drilled holes on the top plate to screw the connection together with 4 tap con screws. , Make sure the connection is secure to complete the top termination. ,,, Use your tin snips to cut a hole in the insulation and meshing where the tee snout will connect to the tee body. , Cover the connection with the leftover liner insulation. , Complete the connection by attaching it to the heating appliance.
