Before installation, ensure that your chimney has been properly swept and inspected for any blockages or damages. Begin by positioning the liner’s top in alignment with the chimney opening. Using a nose cone, gently feed the liner down, ensuring that it negotiates any bends without creasing. Secure the top of the liner with a clamp plate and seal the bottom to the register plate, flue pipe or gas collector, ensuring that at least 75mm of the liner projects above the clamp plate. It is critical to follow the provided detailed instructions during installation, and if in doubt, consult a professional installer to ensure safety and correct setup.

Comprehensive Buyers Guide for the 300mm (12 inch) Flue Liner 316L
When it comes to chimney safety and performance, choosing the right flue liner is paramount. The 300mm Flue Liner 316L is engineered to offer exceptional durability, efficiency and ease of installation. In this guide, we walk you through everything you need to know, from key features and benefits to installation tips and common objections.
Overview and Product Introduction
The 300mm (12 inch) Flue Liner 316L is a state-of-the-art solution designed for relining masonry chimneys that serve gas and oil appliances. Crafted from high-grade 316L stainless steel, this liner combines strength and flexibility, ensuring that your chimney operates efficiently under extreme conditions. With a thickness of 0.10mm and an innovative triplelock sealing system featuring five convolutions between each seam, you can count on this product to perform reliably for years.
Why Choose a 316L Flue Liner?
Durability & Safety: The 316L grade stainless steel construction is highly resistant to corrosion and extreme temperatures. This is particularly essential in environments where consistent exposure to high heat occurs, ensuring that the liner retains its integrity over time.
Efficiency & Reliability: With a robust triplelock sealing method, this flue liner minimises the risk of leaks and improves the overall efficiency of your chimney system. This results in better heat management, lower energy consumption, and a safer environment for you and your family.
Compliance & Certification: Fully Kitemarked to BS 715 and certified to meet BS EN 1856:2 standards, this flue liner meets all the necessary industry regulations. This compliance not only boosts your confidence in the product but also ensures that you remain within statutory safety requirements.
Installation and Maintenance
Installing the 300mm Flue Liner 316L is designed to be straightforward. Begin by ensuring that your chimney is clean and free from obstructions. The installation process involves positioning the liner at the top of your chimney, gently feeding it down using a nose cone, and then securing it at both ends – at the top with a clamp plate and at the bottom with a sealing mechanism that can adapt to registers, flue pipes, or gas collectors. It is crucial that at least 75mm of your flue liner extends above the clamp plate to secure the terminal fitting properly.
Maintenance Tips: Regular upkeep is essential for optimal performance. We recommend sweeping your chimney at least once a year or more frequently as needed. Inspection should be carried out to check for any signs of wear or corrosion, ensuring that the protective features of the stainless steel are maintained. Following these steps can help prolong the lifespan of your flue liner and maintain its performance under challenging conditions.
Addressing Common Concerns and Objections
Concern about Installation Complexity: Many customers worry that installing a flue liner can be complex. However, with the detailed installation instructions provided, most users find that the process is straightforward. Moreover, professional installers are on hand should you require expert guidance.
Worry About Durability: Some potential buyers might be sceptical about the durability of a single-skin liner. The use of 316L stainless steel, known for its strength and resistance to oxidation and corrosion, is designed to counter these concerns. The robust triplelock design further reinforces the liner’s structural integrity.
Heat Tolerance Fears: Our flue liner is engineered to withstand temperatures up to 260°C. This makes it ideal for high-heat applications typical in gas and oil appliances. Such performance specifications ensure that safety and efficiency are not compromised during extended use.
