With over 25 years of experience in the market, this vent pipe stands out for its robust construction and reliability.
Key Features and Their Benefits
High-Quality Construction: The IL Gas Vent Pipe features a twin wall insulated design that offers exceptional thermal efficiency. The inner aluminium liner ensures durability while the outer Zalutite case provides a reliable barrier against corrosion. This combination not only prolongs the product life but also maintains consistent performance even under challenging conditions.
Optimised Installation: With a fixed length of 305mm and an installed effective length of 267mm, the system is designed for ease of installation. The push fit and twist lock joint method ensures a hassle-free assembly, allowing both professionals and DIY enthusiasts to set it up with confidence.
Safety and Compliance: Engineered to handle flue gas temperatures up to 250°C and maintain a safe 50mm distance from combustibles, this vent pipe is rigorously tested and certified (CE and BS EN 9001:2008) to meet UK safety standards. Its design ensures that it performs reliably under negative pressure conditions, making it an ideal choice for naturally aspirated gas appliances.
Installation Guidelines
Before beginning installation, it is critical to review the manufacturer’s instructions. The IL Gas Vent Pipe is versatile and suitable for both internal and external installations, provided that the correct installation procedures are followed. Ensure that:
• There is a minimum clearance of 50mm from any combustible materials.
• Each joint is securely connected using the push fit and twist lock method.
• The vent pipe is positioned on a level surface to avoid any misalignments.
• Regular inspections are carried out to detect any early signs of wear or obstruction.
Following these guidelines will help maintain optimum system performance and prolong the lifespan of your gas vent pipe.
Understanding the Technical Specifications
The product is engineered with precision. With a 6mm air gap separating the inner aluminium liner from the Zalutite outer casing, the vent pipe effectively retains heat and ensures a consistent flow of gases. The specified dimensions and material choices translate into a system that is robust, reliable, and built to last. Whether you are replacing an old system or installing a new one, the IL Gas Vent Pipe provides the technical reliability you require.
Addressing Common Objections
One common concern among homeowners is the compatibility of venting systems with various gas appliances. The IL Gas Vent Pipe is specifically designed for naturally aspirated domestic gas-fired appliances and is not suitable for condensing or positive pressure applications. This clear delineation means that the product is optimized for a specific set of conditions, ensuring that it performs efficiently for its intended use. Additionally, customers sometimes worry about the longevity of materials in harsh weather conditions. With its corrosion-resistant Zalutite outer case and robust construction, the IL vent pipe has been proven to withstand the UK’s variable climate, offering both performance and peace of mind.
Another question often raised is about the installation process. Our vent pipe, designed for swift and easy set-up, utilises a simple push fit and twist lock mechanism that minimises installation time while ensuring a tight, secure fit. For those who may have concerns about DIY installations, our comprehensive installation guidelines and nationwide customer support are available to provide all the necessary assistance.
Comparisons and the Role of Accessories
In today’s market, many homeowners are looking for complete solutions that not only include the core venting product but also complementary accessories that enhance the installation. While the IL Gas Vent Pipe already boasts exceptional features, exploring optional accessories such as flue caps, support brackets, and additional insulation liners can further tailor the installation to your specific needs. These accessories potentially improve overall system performance and ensure regulatory compliance, especially in complex installation scenarios.
