Its robust construction and exquisite matte black finish provide not only an appealing look but also a level of durability that ensures consistent performance in challenging conditions. The product is coated with a 0.3mm layer of powder enamel, a feature that adds extra protection against corrosion, making it ideal for both indoor and outdoor installations.
Key Benefits and Features
Strength and Durability: The use of zero carbon steel ensures that the reducer can endure the rigours of daily use, making it a long-lasting addition to your flue system. This construction material is chosen for its ability to resist deformation, even at high temperatures.
Heat Resistance: With the ability to handle temperatures up to 600°C, this reducer is perfectly suited to work with high-temperature fuels such as oil and solid fuels. This capability ensures that your system remains safe and effective, even during extended periods of use.
Versatility: Designed to work with various fuel types, the MI-VIT Lite Reducer is ideal for a range of applications. Whether your appliance runs on gas, oil, or solid fuel, this reducer provides a secure transition to your flue liner or chimney stack.
Aesthetic Appeal: The matte black finish is not only stylish but also practical. It helps to conceal dirt and wear, keeping your installation looking professional while reducing the frequency of cleaning required.
Safety Compliance: Meeting rigorous standards such as EN1856-2 T600 N1 Vm L8010 G375 ensures that the product is safe for use with combustible materials, provided it is installed correctly with a minimum distance of 375mm from any such materials.
Installation Guidelines
Proper installation is crucial for maximising the performance and safety of your flue system. The reducer must be mounted with the smaller diameter facing downwards. This orientation is essential for trapping condensates, which can otherwise lead to water build-up and potential operational issues. Additionally, maintaining a clearance of at least 375mm from combustible materials is vital for reducing any risk of fire hazards. Use appropriate seals for P1 pressure ratings when necessary, and ensure that installation complies with all relevant local regulation and manufacturer guidelines.
Maintenance and Inspection
Regular maintenance is key to long-term efficiency and safety. For solid fuel applications, it is advisable to have your chimney swept at least once a year, or more frequently if needed. Check that the access doors remain unobstructed so that cleaning and inspection tasks can be performed with ease. Early detection of any wear or corrosion can prevent small issues from escalating into more serious problems, safeguarding your investment and ensuring continued performance.
