Introduction
The Joist Support - Ø 100mm is an essential component in any modern chimney and flue system, designed to ensure both safety and endurance. This guide aims to provide all the necessary details about the product, its installation, and the benefits it offers. Whether you are a homeowner or a professional installer, understanding these key aspects will help you make an informed decision.
Product Overview
Manufactured by National Flues, a leader in high-quality flue systems, the Joist Support - Ø 100mm is engineered for durability and performance. The product is built using a dual-layer stainless steel construction, with the outer skin made from 304 grade stainless steel and the inner skin from 316 grade stainless steel, both at a thickness of 0.40mm. This robust design is further distinguished by its compressed rockwool insulation, designed to maintain high thermal resistance. It is ideal for use with solid fuel appliances such as woodstoves, gas coal effect fires, and boilers that use oil or gas.
Technical Advantages
One of the standout features of the Joist Support - Ø 100mm is its adherence to strict safety standards. With HETAS approval and CE marking, you can be confident that each unit meets rigorous industry protocols. The dual stainless steel construction not only ensures longevity but also provides enhanced resistance to the high temperatures commonly associated with flue systems. The compressed rockwool insulation plays a crucial role in preventing heat transfer, thereby maintaining a safe distance between the flue and any combustible surfaces. These features collectively contribute to a significantly reduced risk of fire hazards.
Installation Process
Preparation
Before beginning installation, inspect the area where the flue will pass through the floor joists. It is imperative to ensure that the support system is free of defects and that the floor joists are structurally sound. Prepare all necessary tools and the Locking Band, which is used to secure the support panels together.
Step-by-Step Installation
1. Position the Joist Support - Ø 100mm across the relevant floor joist, ensuring that it is centred and level.
2. Verify that there is a minimum clearance of 50mm for TWPro or 60mm for KC between the flue and any combustible materials.
3. Secure the support using the provided Locking Band. Follow the manufacturer’s guidelines to ensure each component is securely fastened.
4. Check and double-check alignment before finalising the installation. Small deviations can lead to compromised performance over time.
Final Checks and Safety Considerations
After the installation, it is essential to perform a thorough inspection. Ensure that all connections are tight and that the support system is stable. If uncertainty arises, it is advisable to consult a professional. Safety should always be the top priority during installation. Always adhere to local regulations and guidelines to ensure that the installation is both safe and compliant with industry standards.
Safety & Compliance
Safety is a cornerstone of the Joist Support - Ø 100mm. The precise manufacturing process guarantees that the support system not only meets but exceeds the standard requirements for chimney and flue systems. The mandatory combustible clearance – 50mm for TWPro and 60mm for KC – further ensures that there is no risk of accidental ignition. Additionally, the product’s HETAS certification and CE marking provide additional assurance of its reliability under high-stress conditions. These measures help maintain a secure environment, significantly reducing potential fire hazards.
