How to Install a Flexible Chimney Liner How to Install a Flexible Chimney Liner

Installing a flexible chimney liner is not very difficult if the right steps are followed. The flexible chimney liner can be installed either from the bottom going up or from the top coming down, depending upon the conditions present and also the individual preference of the person who is installing it. Please keep in mind, though, that the largest fitting liner must be selected so that there is enough space left in the chimney after installing the liner.

Let us see how the flexible chimney liner will be installed.

You Will Need

  • Cleaning brush
  • Chimney liner
  • Probe
  • Pulley and rope
  • Screws and other things to fix the liner
  • Cement and vermiculite

Step 1 – Clean the Chimney

You will need to clean the chimney thoroughly so that no blockages left in it at the time of installing the liner. The barriers can be checked with the help of a probe, which will also calculate the dimensions inside the chimney. The chimney can be cleaned by moving the chimney brush in the chimney.

Step 2 – Prepare the Liner

Open the packaging of the liner and keep it flat on a straight surface. Attach the bottom termination connector. Flexible chimney liners can be stainless steel, as well as other materials. You will have to choose the one that will be right for your budget and the chimney.

Step 3 - Set up the Pulley

If you plan to install the liner from above, you will set up the pulley at the top. Lower a rope down the chimney, which will be later joined with the chimney liner. Make sure that you are wearing gloves to protect your hands from the sharp metal edges of the liner and its parts.

Step 4 – Align the Liner

With the help of the pulley, get the chimney liner in the right alignment, but be very slow so that you do not end spoiling the liner in any manner. It is a tedious task and you may have to try a few times before you get the liner in the right direction. Now, tighten all the screw plates that are present at the bottom of the chimney so that the liner stays in place and so that no smoke can come enter the house from the smoke compartment of the chimney.

Step 5 - Finish up

In the space between chimney wall and chimney liner, transfer a combination of cement and vermiculite. This combination will lead to insulation of the chimney, which in turn will make the chimney hot more quickly. Therefore, the stove will get hot faster.

There are some other ways to install a chimney liner, such as installing it from the bottom and going up. In such a case, a pulley will have to be attached either at the top or bottom of the liner, and then the liner will be pulled up through the chimney where is will pass through the smoke compartment of the chimney.
