Introduction
When it comes to installing or upgrading your domestic gas vent system, choosing the right components is vital for both safety and performance. The IL - Tee Cap - Ø 125 from National Flues is a purpose-built accessory designed to cap the end of a 90-degree tee in twin wall insulated gas vent systems. With over 25 years of industry expertise, this product has been meticulously engineered for naturally aspirated gas-fired appliances operating under negative pressure. In this buyer's guide, we will explore its features, installation process, and why it stands out compared to other vent system components. We’ll also delve into complementary optional accessories that can enhance the overall installation, ensuring you achieve a reliable and efficient gas vent system.
Product Overview
The IL - Tee Cap - Ø 125 is more than just a simple closure for your vent system. It is crafted with an aluminium inner liner for excellent heat resistance and a durable, corrosion-protected zalutite outer casing. The intelligently designed 6mm air gap between these layers delivers optimal insulation, which is critical in maintaining the correct operating temperature and ensuring long-term safety. With a push fit and twist lock joint method, the installation is straightforward yet secure, making it an ideal component for both new installations and retrofits.
Exceptional Engineering and Materials
Material Quality: The use of an aluminium liner combined with a zalutite outer case makes the IL - Tee Cap a robust and reliable choice. The aluminium offers a lightweight yet strong base, while the zalutite provides an extra layer of protection against corrosion. These materials have been chosen to ensure that the product can withstand the rigours of high-temperature flue gases, which can reach up to 250°C.
Design Precision: The 6mm air gap is not just a design feature; it is critical for insulation. This gap serves as a thermal break, reducing heat transfer and maintaining system efficiency. The push fit and twist lock mechanism further ensure that once installed, the tee cap remains securely in place under a variety of operating conditions.
Installation and Safety
Step-by-Step Installation Process
- Preparation: Before you begin, make sure the gas vent system is completely depressurised. Safety is paramount, so it’s advisable to have a professional carry out or at least supervise the installation.
- Inspection: Verify that the 90-degree tee is clean and free of any obstructions. Inspect the components to ensure that they are in optimal condition for installation.
- Installation: Align the tee cap with the 90-degree tee and engage the push fit mechanism. Then, twist the cap to lock it in place. This two-step process guarantees a tight seal which is crucial for the safe venting of flue gases.
- Clearance: Always maintain a minimum distance of 50mm from any combustible materials to comply with safety regulations.
Critical Safety Considerations
It is important to note that this tee cap is designed for use with naturally aspirated, gas-fired appliances under negative pressure conditions. It is not suitable for condensing or positive pressure systems. Always follow the manufacturer’s guidelines to prevent any hazardous situations. If you are unsure about any aspect of the installation, consult with a qualified engineer.
