The EuroSW1 Increaser (Ø 125-150mm) is engineered to suit gas, oil, and solid fuel appliances with temperatures reaching up to 600°C. Made from durable zero carbon steel, this single skin connecting flue pipe is perfect for linking your appliance to a Flue Liner, Chimney Stack, or Twin Wall Flue System. Note that it should not pass through ceilings or combustible walls, and must be at least 375mm away from combustible materials like wood or plasterboard during installation.

Featuring a friction fit joint, it ensures secure connections without the need for sealing—although adding fire cement or high-temperature silicone sealant can offer extra security. Designed for cutting, remember to coat any exposed steel with high-temperature paint to prevent rusting. Regular maintenance is essential, particularly for solid fuel applications, to ensure peak performance and safety.
