What it is

The Venturi - Fan Connecting Piece is a Broag commercial boiler component that links the fan to the combustion air and gas mixing path. It is sized for appliances built with 7 to 10 sections. The venturi creates the pressure differential that draws gas into the air stream, so correct fan-to-venturi sealing and alignment matter for stable combustion.

Signs this part needs replacing

  • Combustion readings drifting outside the expected range for the appliance
  • Unstable or rough burner operation at start-up or during modulation
  • Visible cracking, distortion or damage to the venturi body
  • Soot deposits or scorching around the fan and venturi connection
  • Leaks or failed seals at the fan-to-venturi joint

Before you order

  • Confirm the appliance model and the number of sections it is built with, as this part is specified for 7 to 10 sections
  • Check the existing venturi and fan connection for damage, and note the part number on the component being replaced
  • Verify that the boiler is isolated and the gas supply is shut off before any work begins
  • Confirm that combustion settings will be checked and reset after fitting
