Installation Guidelines
Successful installation is key to unlocking the full benefits of the TWPro GREY 135° Tee. The installation process involves securing the components using a locking band. It is imperative that a minimum clearance of 50mm is maintained from any combustible material such as wood or plasterboard. This safety distance is crucial in preventing overheating and ensuring that the chimney operates within safe parameters. While many experienced installers may find the process straightforward, those less familiar with chimney systems should consider engaging a professional. Our installation guidelines are comprehensive and designed to support both new installations and retrofit applications.
Optional Accessories and Additional Upgrades
While the TWPro GREY 135° Tee comes complete with features to meet standard chimney requirements, there are optional accessories available that can further optimise performance and enhance safety. Accessories such as additional sealing kits, bespoke mounting brackets, or specialised flue liners may be useful in certain setups. We encourage you to explore our accessory catalog to ensure that every component of your chimney system works together seamlessly.
Addressing Common Concerns
Installation Difficulties: Some users might be apprehensive about the installation process, particularly if working with older chimney structures. However, our detailed installation manual, coupled with professional support options, is designed to simplify the process. Ensure that your installer is familiar with current UK standards and that all safety clearances are strictly adhered to.
Material Quality: Concerns about material performance under prolonged exposure are common. The combination of 304 and 316 grade stainless steel ensures not only strength but also excellent resistance to rust and corrosion. This means long-term reliability regardless of the environmental conditions your chimney may face.
Maintenance Requirements: Routine maintenance is a critical aspect of ensuring the longevity of your chimney system. The design of this tee allows for easy cleaning access, which is integral to preventing soot build-up and improving overall air quality. Regular inspections and maintenance will further extend the life of your installation.
