What it is
The Biasi BI1782109 is an outlet pipe for the condensing heat exchanger used across the Biasi Advance boiler family. It forms part of the condensate and flue gas path on the secondary heat exchanger, carrying condensate away from the exchanger body. It is a serviceable component, so it can be renewed without replacing the complete heat exchanger assembly.
Signs this part needs replacing
- Visible weeping or dripping at the pipe connection to the heat exchanger
- Corrosion, pitting or white scale deposits on the pipe wall
- Cracks, splits or deformation in the pipe body
- Condensate collecting inside the casing rather than draining away
- Staining or water tracking on components below the heat exchanger
Before you order
- Confirm the boiler model and GC number from the appliance data badge
- Check whether the appliance is natural gas or LPG, as both variants use this part
- Inspect the pipe seals and connections at the same time, as these are disturbed during replacement
- Compare the part number on the existing component against BI1782109 before ordering
