Installing a chimney liner for your fireplace insert is a crucial step in ensuring safe and efficient operation. A properly installed liner enhances draft, protects the chimney structure, and contains potential hazards. In this guide, we’ll walk you through the precise steps to install a chimney liner for your fireplace insert.
Materials Needed:
Chimney Liner Kit: Ensure it is the correct size and material for your specific application.
Liner Top Plate: This forms a seal at the top of the chimney.
Chimney Liner Adaptor: Connects the liner to the stove or insert.
Support Clamp and Tee Cap: Keeps the liner in place and diverts any condensation or creosote back into the insert.
Silicone Sealant: Provides an airtight seal for joints.
Step 1: Measure and Prepare
Measure the Chimney: Determine the length of liner needed by measuring the inside of the chimney from the top of the insert to the top of the chimney.
Assemble the Top Plate: Attach the top plate to the liner, ensuring it’s secure.
Step 2: Install the Top Plate
Position the Top Plate: Lower the liner assembly down the chimney until the top plate reaches the top.
Seal the Top Plate: Apply a bead of silicone sealant around the edge of the top plate and press it firmly against the chimney’s surface.
Step 3: Connect the Liner Adaptor
Insert the Liner: Lower the liner with the attached top plate down the chimney until the liner adaptor reaches the insert.
Attach the Liner Adaptor: Connect the liner adaptor to the insert’s exhaust outlet, ensuring a snug fit.
Step 4: Secure the Liner
- Use Support Clamps: Secure the liner to the chimney wall at regular intervals, ensuring it remains centered and straight.
Step 5: Seal Joints
- Apply Sealant: Inspect all joints and connections. Apply silicone sealant to any areas where air leakage could occur.
Step 6: Install the Tee Cap
Position the Tee Cap: Attach the tee cap to the bottom of the liner, ensuring it diverts any condensation or creosote back into the insert.
Secure the Tee Cap: Use support clamps to keep the tee cap in place.
