The VIT-Smooth Increaser - Ø 175-200mm is a top-notch connecting flue pipe designed to seamlessly transition between flue systems of different diameters. Ideal for gas, oil, and solid fuel appliances operating at temperatures up to 600°C, this increaser serves as a crucial component for ensuring efficient and safe operation. Crafted from zero carbon steel and coated with a powder vitreous enamel in a matte black finish, the VIT-Smooth Increaser offers superior durability and a sleek appearance.

It is essential to use this pipe only as a connection between your appliance and the flue liner, chimney stack, or twin wall flue system, and not to pass through ceilings or combustible walls to ensure safety and compliance with building regulations. Installation is straightforward, with the smaller diameter end pointing downward to keep condensates within the flue system. Friction-fit joints eliminate the need for sealants, though optional jointing compounds can be applied for additional security.

Regular maintenance, including sweeping and inspection, is recommended, particularly for solid fuel applications to ensure optimal performance and longevity.
