Quick Answer
Flexible chimney liners are a popular choice for wood stove installations due to their ease of installation and flexibility during tight spaces. To ensure a safe and efficient installation, follow these best practices.
Measuring and Cutting
When installing flexible chimney liners, it’s essential to measure the interior of the chimney and the stove pipe to determine the correct size and length of the liner. Use a tape measure to record the dimensions and subtract 2-3 inches from the length to account for any bends or turns in the liner. Cut the liner using a utility knife or a pipe cutter, leaving about 1 inch of extra material at the cut end for trimming.
Installing the Liner
Begin the installation by attaching the liner to the wood stove using a secure clamp or band. Make sure the liner is centered and free of any kinks or creases. Next, feed the liner through the chimney, using a gentle twisting motion to navigate any tight spaces. Secure the liner to the chimney using a liner clamp or clip, making sure it’s tightened securely but not over-tightened, which can cause damage to the liner or chimney.
Sealing and Testing
Once the liner is installed, inspect the joints and connections for any signs of leakage or gaps. Use a high-temperature sealant, such as caulk or mastic, to seal any gaps or cracks around the liner and chimney. Finally, perform a smoke test by lighting the stove and checking for any leaks or drafts in the liner. If you detect any issues, address them promptly to ensure a safe and efficient installation. It’s also a good idea to have your installation inspected and certified by a qualified professional.
