Comprehensive Buyers Guide for the Non-concentric Increaser 2 Diameters - Ø 300
When selecting components for your commercial flue system, every detail matters. The Non-concentric Increaser 2 Diameters - Ø 300 from National Flues is not only a critical component for improving system efficiency, but it is also designed with precision and care to meet the highest industry standards. In this guide, we will explore everything you need to know about this product, address common concerns, and help you understand why it is the right choice for your installation.
Overview of the Product
Our Non-concentric Increaser is engineered from high-grade 316L stainless steel, ensuring that it can withstand the rigours of high-pressure and condensing applications. Its robust construction, coupled with a design that meets the EN 1856-1 standards, guarantees that your installation will be safe, durable, and reliable. This product is specifically designed to increase the diameter of the flue system while preventing condensate pooling, a common issue in inclined flue runs that can hamper performance and increase maintenance costs.
Key Features and Their Benefits
Durability and Quality:
The difficulty of maintaining a reliable flue system in commercial operations cannot be understated. By opting for our increaser, you are choosing a product that is built to last. The 316L stainless steel material is renowned for its resistance to corrosion and wear, making it an ideal choice for harsh operating conditions.
Safety and Compliance:
Safety is paramount when planning any flue system. Our product is CE marked and adheres to EN 1856-1 standards, which means it has been rigorously tested to meet strict safety guidelines. This offers assurance that the increaser will perform reliably under both high and low-temperature conditions and contribute to a secure operation overall.
Ease of Installation:
Installation can often be a challenging aspect of system design, but the push-fit jointing system incorporated in our increaser significantly simplifies the process. With a secure locking band, the component fits seamlessly into your existing setup. This reduces the risk of incorrect assembly and minimizes installation time and costs.
Addressing Common Concerns
Condensate Pooling:
One of the noted challenges in flue system installations is the accumulation of condensate, particularly in inclined configurations. The design of the Non-concentric Increaser effectively prevents condensate pooling by maintaining an optimal slope and ensuring all connections are meticulously sealed. This design aspect is crucial for maintaining system efficiency and reducing long-term maintenance issues.
Temperature Variations:
Commercial flue systems often encounter a wide range of temperatures. Our increaser is specifically designed to handle both extreme hot and cold operations. This flexibility in temperature tolerance enables it to perform reliably under various operational conditions, ensuring stable and continuous operation regardless of environmental influences.
Installation Safety:
It is essential to adhere to installation guidelines to avoid potential hazards. A minimum clearance of 50mm from combustible materials is required to mitigate any fire risk. Always ensure that jointing gaskets are installed at each connection point. Following these guidelines not only enhances the safety of your installation but also promotes its longevity and overall performance.
Performance Under Pressure:
The inclusion of high-pressure sealing gaskets (P1/H1) means the system maintains a robust positive and negative pressure seal. This is crucial for preventing leaks and ensuring that the air flow within the flue system remains optimally balanced. Such reliability in maintaining pressure is a key benefit for any commercial installation aiming to maximize both efficiency and safety.
Installation Tips
For a seamless installation process, it is recommended that all components, including jointing gaskets and locking bands, are inspected before assembly. Follow the detailed guidance provided in your instruction manual, and do not hesitate to consult with a specialist if necessary. Remember, a properly installed system not only functions better but also prolongs the lifespan of your investment.
