The VIT-Smooth 500mm Pipe (Ø 150mm) is a high-quality connecting flue pipe designed for use with gas, oil, and solid fuel appliances capable of reaching temperatures up to 600°. Constructed from zero carbon steel with a durable powder vitreous enamel coating in a matt black finish, this pipe delivers both functionality and aesthetic appeal.Ideal for connecting your appliance to a Flue Liner, Chimney Stack, or Twin Wall Flue System, the VIT-Smooth pipe ensures a perfect fit with its friction joint system, eliminating the need for sealing. For extra security, jointing compounds such as fire cement or high-temperature silicone sealant can be applied.Note that the VIT-Smooth should not be used to pass through ceilings or combustible walls and must be installed correctly, with the smaller diameter pointing downwards to keep condensates within the system.

Maintenance is also simplified with the option to include access doors for easy inspection and cleaning, crucial for solid fuel systems. Installing this pipe requires appropriate PPE and should adhere to safety guidelines.

When installing the VIT-Smooth pipe, ensure that all recommended safety procedures are followed. The pipe must be installed with its smaller diameter oriented downwards to correctly contain any condensates within the system. It is essential that the pipe is not used to pass through ceilings or combustible walls. A friction fit joint system is utilized, which generally negates the need for additional sealing compounds, although fire cement or high-temperature silicone sealant can be applied for extra joint security if desired. Installation should be performed by a qualified professional using appropriate personal protective equipment (PPE). Optional accessories, such as access doors, are available to facilitate routine maintenance and ensure long-term performance.
