Chimney flue installation tips

If you want to use an old chimney that hasn’t been used in a long time, do not do so without inspecting it. Installing a chimney flue can save your life, protecting you from the toxic gases that result when burning fuel. The task of installing a flue will take several hours and doesn’t require a professional’s help.

Tools and materials needed

  • Screwdriver
  • Flue liner
  • Metal sheeting
  • Screws

Chimney cleaning

You must start by cleaning the chimney of any aged soot deposits. This way you will also see if the chimney is damaged or not. If you detect any missing bricks or any other signs of damage, it is crucial that you repair the chimney before you install the chimney flue.

Flue installation

Use metal sheets to build the flue. Roll them so they’re smaller than the chimney opening. After that, screw the edges together. Attach a string to the upper end of the flue and have someone pull it up through the chimney from the top. Nail the flue at the top.

Liner installation

After the flue has been installed, you must install a flue liner. The flue liner must be fitted inside the flue. The liner is installed to keep the liner clean and prevents heat from escaping. The liner must be lowered down the flue and sealed at the top of the chimney using a band that comes with the liner kit. The bottom of the liner must be connected to the chimney buffer.

Finishing touches

Make sure the flames from the fireplace can’t reach the flue and the liner. Try not to leave gaps in the flue because they may allow gas to escape.
