Before we dive into the installation process, it’s important to understand the different types of chimney liners available. The liner you choose will depend on your chimney’s design, the type of appliance you’re using, and your budget.

Clay Liners

Clay liners are the most traditional and affordable option. They’re made of clay tiles that fit together to line the inside of the chimney. Clay liners are durable and can withstand high temperatures, but they’re not suitable for all chimney types.

Metal Liners

Metal liners are a popular choice for their versatility and durability. They come in various materials, including stainless steel, aluminum, and titanium, and can be used for most chimney types. Metal liners are easy to install and provide excellent insulation, making them a cost-effective option in the long run.

Cast-in-Place Liners

Cast-in-place liners are a more expensive option that provides excellent insulation and a seamless lining for your chimney. This type of liner is made by pouring a cement-like mixture into the chimney, creating a custom-fit liner. Cast-in-place liners are ideal for chimneys with irregular shapes or damage.

Tools and Materials Needed

Before you begin installing a chimney liner, you’ll need to gather the necessary tools and materials. Here’s a list of what you’ll need:

  • Chimney liner kit: This includes the liner itself, insulation, and all the necessary hardware.
  • Measuring tape: You’ll need to measure the dimensions of your chimney and liner to ensure a proper fit.
  • Metal cutting tools: Depending on the type of liner you’re using, you may need to cut it to size.
  • Wire brush: You’ll need this to clean the interior of the chimney before installing the liner.
  • Gloves: Safety should always be a top priority when working with chimneys. Wearing gloves will protect your hands from sharp edges and other hazards.

Steps to Install a Chimney Liner

Now that you have all the tools and materials, let’s walk through the steps to install a chimney liner.

Step 1: Measure the Chimney and Liner

Measure the length and diameter of your chimney and liner to ensure a proper fit. You’ll also need to measure any offsets or bends in the chimney to determine how much liner you’ll need.

Step 2: Prepare the Chimney and Liner

First, clean the interior of the chimney with a wire brush to remove any debris or creosote buildup. Next, assemble the liner kit according to the manufacturer’s instructions. If necessary, cut the liner to size using metal cutting tools.

Step 3: Install the Liner

Carefully lower the liner down the chimney, making sure it’s centered and straight. Use the hardware included in the kit to secure the liner to the chimney walls.

Step 4: Connect the Liner to the Stove or Furnace

Once the liner is in place, connect it to your stove or furnace using a connector pipe. Make sure the connection is airtight and secure.

Step 5: Seal the Connections

Seal the connection between the liner and the stove or furnace using high-temperature silicone sealant. This will prevent any gases from escaping and ensure safe operation.

Step 6: Inspect the Installation

Finally, inspect the installation to ensure everything is secure and in good working order. It’s always a good idea to have a professional chimney sweep inspect your work to ensure everything is up to code.

Safety Precautions

Installing a chimney liner requires working with high temperatures and potentially dangerous materials. To ensure your safety during the installation process, follow these safety precautions:

Use Protective Gear

Wear protective gear, including gloves, safety glasses, and a dust mask, to protect yourself from dust, debris, and high temperatures.

Keep Fire Extinguisher Nearby

Have a fire extinguisher nearby in case of an emergency. Make sure you know how to use it before starting the installation process.

Work with a Partner

Installing a chimney liner can be a two-person job. Having a partner can help ensure your safety and make the installation process run more smoothly.


Installing a chimney liner is an important step in maintaining the safety and efficiency of your chimney. A properly installed chimney liner can protect your home and family from dangerous gases and creosote buildup.

To recap, the installation process involves measuring your chimney and liner, preparing the chimney and liner, installing the liner, connecting the liner to the stove or furnace, sealing the connections, and inspecting the installation.

In conclusion, if you’re not confident in your ability to install a chimney liner, it’s best to hire a professional. However, if you follow the steps outlined in this guide and take the necessary safety precautions, you can successfully install a chimney liner yourself and enjoy a safer and more efficient fireplace or wood-burning stove.
