What it is
The Biasi BI1563104 is a fan assembly manufactured for the Biasi Advance range of gas boilers. It draws combustion air into the burner and pushes flue products out through the flue system, and its speed is monitored by the boiler's control board to prove correct combustion airflow before and during firing. A failed or sluggish fan will normally stop the appliance from lighting or running.
Signs this part needs replacing
- Boiler fails to light or locks out shortly after the fan is called
- Grinding, rumbling or squealing noise from the fan area on start-up
- Fan runs intermittently, slows, or does not spin at all
- Repeated fan or airflow fault codes on the boiler display
- Visible damage, play or contamination at the fan impeller or housing
Before you order
- Confirm the boiler model and gas type from the appliance data badge
- Check the part number on the existing fan matches BI1563104
- Isolate the electrical supply and gas before removing the old fan
- Inspect the flue and fan mounting for debris or damage before fitting
