The VIT-Smooth 250mm Pipe with Door - Ø 150mm by National Flues is an exceptionally designed connecting flue pipe, ideal for gas, oil, and solid fuel appliances that operate at temperatures up to 600°C. Fabricated using zero carbon steel and finished with a powder vitreous enamel coating in elegant matt black, this single-skin flue pipe is both durable and visually appealing. It is specifically designed to create a seamless connection between your appliance and the Flue Liner, Chimney Stack, or Twin Wall Flue System.

Notably, the VIT-Smooth pipe should not be used to penetrate ceilings or combustible walls. This pipe features an access door, which simplifies maintenance and allows for easy inspection and cleaning of the chimney, essential for solid fuel applications. The robust friction-fit joint system ensures a secure fit without the need for sealing, though jointing compounds can be used for additional security.

Care should be taken to install the pipe with the smaller diameter pointing downward, thereby containing any condensates within the flue system. Additionally, this pipe can be cut to size, provided exposed steel is coated with high-temperature paint to prevent rusting over time. Always wear appropriate PPE during installation to maintain safety.

When installing the VIT-Smooth 250mm Pipe, ensure that the smaller diameter is oriented downwards to effectively contain any condensate. The pipe should be assembled using its friction-fit joint system, which does not require sealing under normal conditions; however, jointing compounds may be applied for extra security if preferred. Always cut the pipe to the required size with precision and, if any steel is exposed, ensure it is coated with a high-temperature paint to prevent rusting over time. Wear appropriate PPE during installation. Optional accessories such as sealing compounds, high-temperature paints, and connector kits can further enhance the system's integrity and longevity.

Yes, the VIT-Smooth pipe is suitable for use with gas, oil, and solid fuel appliances, as long as temperatures do not exceed 600°C.

No, the VIT-Smooth pipe should not be used to pass through ceilings or combustible walls.
