What customers say
The Z-Flex Chimney Liner Kit garners overwhelmingly positive sentiment, positioning it as a premium, reliable solution for critical chimney venting needs. Customers frequently praise the exceptional quality of the 316L stainless steel, noting its robust construction and impressive flexibility, which significantly aids in navigating complex flue bends during installation. This flexibility is a key differentiator, often cited as making the daunting task of relining a chimney manageable. The completeness of the 50-foot kit—often including essential components like the top plate, rain cap, and appliance connector—is a major selling point, providing excellent perceived value despite the high initial investment. Reviewers consistently highlight the peace of mind derived from using a product that meets stringent safety standards, especially when venting high-efficiency appliances or wood stoves, emphasizing its role as a durable, long-term infrastructure upgrade. While the sheer weight and bulk of the 50-foot length are occasionally mentioned as logistical challenges requiring two people for safe handling, this minor friction point does not detract significantly from the overall satisfaction. A recurring theme is that while the cost is high, the longevity and superior performance justify the expenditure, leading to a strong recommendation rate. The consensus is that the Z-Flex liner performs exactly as advertised, making it a highly recommended choice for both experienced DIYers and professional installers seeking top-tier materials and safety assurance.
Know before you buy
No, this specific kit is designed for use with natural gas, oil, and pellet appliances. It is not rated for wood-burning stoves, which require different temperature ratings and materials.
The fully flexible construction is specifically designed to navigate offsets and bends in a chimney flue. This flexibility makes it much easier to install than rigid pipe, though you should still ensure the liner is not kinked or crushed during the process.
Being UL Listed means this product has been tested by Underwriters Laboratories to meet specific safety and performance standards. This certification is often required by local building codes and insurance providers to ensure the liner can safely handle the heat and exhaust from your heating appliance.
This kit is comprehensive and includes the essential components for a standard installation, such as the rain cap, flashing, mortar collar, and the liner itself. Depending on your specific chimney setup, you may only need basic hand tools and high-temperature sealant to complete the job.
Yes, the stainless steel liner can be cut to the exact length required for your chimney. Ensure you use appropriate metal-cutting tools to achieve a clean edge and follow all safety precautions when handling the cut material.
