The VIT-Smooth - 90° Rosette Collar (Spring Fix) - Ø 100mm is an essential component for anyone installing a flue system for gas, oil, or solid fuel appliances, supporting temperatures up to 600°C. This product is crafted from zero-carbon steel, ensuring robust durability while the powder vitreous enamel coating in a sleek matt black finish adds a sophisticated touch to your installation. Designed solely as a connecting pipe, it offers seamless integration between appliances and a Flue Liner, Chimney Stack, or Twin Wall Flue System, though it must not be used to pass through ceilings or combustible walls.

The clever friction fit joint design eliminates the need for seals though for added security, joints may be fortified with high-temperature silicone sealant or fire cement. Be sure to install VIT-Smooth in the correct orientation to prevent condensate leakage and rust-proof any exposed steel post-cutting with high-temperature paint. For optimal performance and safety, follow all installation guidelines, don proper PPE, and conduct regular maintenance, especially for solid fuel setups.

Ensure correct orientation by positioning the smaller diameter end downward to prevent condensate leakage. Always maintain a minimum distance of 375mm from any combustible material as specified. Although the friction fit joint minimises the need for additional sealing, you may opt to use high-temperature silicone sealant or fire cement for enhanced security. Wear appropriate Personal Protective Equipment (PPE) during installation, and be sure to follow manufacturer guidelines for regular maintenance. Once cut, any exposed steel should be promptly treated with high-temperature paint to inhibit rust.

The VIT-Smooth 90° Rosette Collar is ideal for gas, oil, and solid fuel appliances that operate at temperatures up to 600°C.

No, it must not be used to pass through ceilings or combustible walls. Use VIT-Smooth solely for connecting appliances to Flue Liners, Chimney Stacks, or Twin Wall Flue Systems.

The collar is manufactured from zero-carbon steel, finished with a powder vitreous enamel coating in matt black for superior durability and aesthetics.

The VIT-Smooth should be installed with the smaller diameter pointing downward to keep condensates within the flue system. Ensure it is at least 375mm away from combustible materials.

The friction fit design does not require joint sealing. However, for extra security, joints can be sealed with high-temperature silicone sealant or fire cement.

Chimneys should be inspected and cleaned at least once a year, though more frequent maintenance may be necessary depending on use.

Always wear appropriate Personal Protective Equipment (PPE) to ensure safety during the installation process.
