WHY DO I NEED A LINER?

When installing a wood insert into a zero-clearance fireplace, it is required to install a UL listed liner. The chimney pipe on a zero-clearance fireplace is only rated to 1700 degrees. The chimney for a high efficient wood insert needs to be rated to 2100 degrees. To maintain UL listing and keep the fireplace to code, the proper liner must be installed. ⁠

WARNING: Installing a chimney liner or chimney liner components in any space other than a code-compliant masonry chimney is extremely dangerous, creates a severe fire hazard and voids any and all warranties. To ensure safety and compliance with building codes, the liner type and material must match the approved appliance and fuel type, and installation must only be performed by a licensed or certified installation professional. See the installation for further details.
