When it comes to choosing a gas vent system, safety, durability, and ease of installation are paramount. The IL 152mm fixed length pipe by National Flues has been designed to meet these critical needs, and this guide will walk you through everything you should know before making your purchase.
Introduction
The IL gas vent pipe is a solution trusted across the UK for over 25 years. Engineered for naturally aspirated domestic gas-fired appliances, its robust design features an aluminium inner liner and a zalutite-coated outer shell, with a 6mm air gap that provides superior insulation. Whether you are renovating an existing system or upgrading to a higher efficiency model, this pipe is designed to deliver both performance and peace of mind.
Key Features and Their Benefits
Durability and Safety: The use of high-quality materials such as aluminium and zalutite ensures that the IL pipe is not only durable but also resistant to corrosion. This means that even in harsh outdoor conditions or in environments where chemical exposure is a concern, the pipe maintains its integrity. Safety is further enhanced as it can safely handle flue gas temperatures up to 250°C, keeping you and your property secure.
Efficient Thermal Performance: The twin wall insulated design with a 6mm air gap plays a critical role in reducing energy loss and condensation. This insulation helps maintain a steady temperature, thereby boosting efficiency and reducing the risk of moisture-related issues. As a result, your venting system will perform reliably even in fluctuating weather conditions.
Simple Installation: One of the standout features of the IL 152mm pipe is its push fit and twist lock joint system. This design simplifies the installation process significantly, allowing both professionals and DIY enthusiasts to complete the setup with minimal fuss. The secure, tight connection not only improves safety but also reduces the potential for installation errors, saving both time and money.
Technical Specifications
Understanding what you are investing in is vital. The IL fixed length pipe comes with robust technical specifications that guarantee its performance. With a length fixed at 152mm (6 inches) and available in 100mm, 125mm, and 150mm diameters, it is engineered for precision in installations. The aluminium inner liner ensures smooth passage for flue gases, while the dual-layer construction with a zalutite exterior provides added protection against the elements and potential corrosion. The product meets critical industry approvals including CE and BS EN 9001:2008, reaffirming its qualification for safe, long-term use.
Installation Considerations
Proper installation is essential for the optimal performance of your gas vent system. Start by ensuring that you have enough clearance. The IL pipe must be installed with a minimum distance of 50mm to any combustible materials to maintain maximum safety. Utilize the straightforward push fit and twist lock mechanism to secure the pipe without the need for complex tools or additional fasteners. After assembly, conduct a thorough inspection of all connections and ensure that the system adheres to local building and safety regulations.
