Installing a chimney liner is one way to ensure that you are fully insulated from cold and draughts. Chimney liners also reduce the risk of smoke and toxic gases entering the home when you are using an older chimney, or one which has been damaged by bad weather. Installing a chimney liner can help save money on your fuel bills, and can be done in a couple of hours if you follow a few simple step-by-step guidelines.

Step 1 - Preparing the Chimney

Before you start installing the liner, it is a good idea to check the chimney and make sure there are no blockages or lumps of soot which could damage the liner. Insert the probe first, and make sure that it emerges from the top of the chimney. The probe is also an excellent way of measuring the length of your chimney, so mark the point of the probe where the probe reached the top of the chimney. Once you have checked for blockages, clean the chimney using a brush. The cleaning is best done from the top down, to insert your brush into the chimney and let it travel to the bottom before pulling it up.

Step 2 - Preparing the Liner

Remove the chimney liner from its packaging, and trim it to the length indicated by the probe. You can cover the liner in a layer of insulation, which will also help to keep the chimney wall warm, but it is not necessary. You should be able to hold the chimney liner in an upright position by lifting the plates at the bottom.

Step 3  - Inserting the Liner

Place the winch on top of the chimney, and trail the rope down the center of your flue. Take the rope and attach it to the top of the liner, then slowly winch the liner up the chimney by triggering the winch. Draw the liner up slowly, to protect it from damage on the edge of the flue. Once the liner is at the top, secure the liner to the chimney using caulk. Place the top plate over the liner, and then press this down into the caulk. Tighten a clamp around the edge of the chimney, keeping the liner in place.

Step 4 - Finishing Touches

Screw the plates at the bottom of the liner into the chimney, and secure to the wall with mortar. Take the stove spout and attach it to the bottom of the liner, and then caulk and cement around the outside to produce a secure lining. If you choose, you can also mix cement and vermiculite together and pour this into your chimney between the liner and the stone. This will also help to keep the chimney properly insulated.

Once the liner has been fitted, maintain it regularly by inspecting the conditon of the liner from the top of the chimney. If you spot any signs of damage, you will have to get a professional chimney expert in to remove the lining, and fit another. Hopefully, this will not happen for many years.
