What it is

The Ferroli Condensate Trap FM.T3B0 Kit, part number 3980H840, is the condensate collection and drainage component used on Ferroli Bluehelix Hitech RRT combi boilers. It collects the acidic condensate produced during combustion and discharges it to the condensate drain. The trap also forms part of the flue gas seal on the appliance.

Signs this part needs replacing

  • Water leaking or dripping from the trap or the pipework beneath the boiler
  • Condensate overflowing from the trap instead of draining away
  • Gurgling or bubbling noises from the trap during operation
  • Boiler locking out or shutting down because condensate cannot drain
  • Visible sludge, debris or scale build-up inside the trap body

Before you order

  • Confirm the boiler model against the fitment list above
  • Check the part number on the existing trap or in the manufacturer's parts list
  • Inspect the condensate pipework and drain for blockages before fitting a replacement trap
  • Check that the kit contents match the trap currently fitted to the appliance
