The Worcester 8000 F 80/125 Vertical Flue Kit is a flue system designed specifically for the Worcester Bosch 8000 F floor-standing boiler range.

Here’s what it is and what it does:

Key Details

• Purpose: It allows the safe discharge of combustion gases vertically through a roof, ensuring compliance with building and safety regulations.
• Flue Size:
  • Inner diameter: 80 mm (for exhaust gases)
  • Outer diameter: 125 mm (for air intake)
    This is a concentric flue system, meaning it combines air intake and exhaust in one assembly.
• Compatibility:
  • Exclusively for Worcester Bosch 8000 F boilers.
  • Not compatible with older Greenstar Highflow or FS CDi models.
• Installation:
  • Passes through the roof for vertical termination.
  • Requires correct measuring and cutting for length adjustment.
  • Must maintain roof-exit clearances and follow safety standards.
• Material: Durable, corrosion-resistant construction for longevity.

Why Use 80/125?

The larger diameter than the standard 60/100, makes it suitable for installations with longer runs or multiple bends.
