This Worcester Bosch 60 mm / 100 mm horizontal high rise Flue Kit is designed for wall-hung gas boilers, especially for installations where the flue must extend vertically through a building's external wall. It provides a complete flue fitting for expelling steam and gases produced during a boiler's normal operation. Key features include a fixed length of 890mm for a rigid, non-adjustable flue path, a high rise design suitable for multi-storey buildings, and an aluminium inner flue for durability and corrosion resistance. The kit complies with the latest building regulations, ensuring safety and performance. It is also compatible with Worcester Bosch's plume management kits for flexible flue gas redirection.
