What it is

The Baxi 5122316 is a pressure sensing venturi used in 40kW gas combi boilers. It sits in the air/gas path and creates a measurable pressure differential that the boiler uses to monitor combustion air flow. It is fitted across the Baxi Duo-tec, Baxi Platinum and Potterton Titanium 40kW combi families.

Signs this part needs replacing

  • Boiler locks out or fails to fire consistently, with air pressure or fan-related fault codes
  • Combustion readings drift or cannot be set within tolerance
  • Whistling or unusual noise from the air/gas intake area
  • Unstable flame signal or repeated ignition attempts
  • Visible blockage, debris or damage at the venturi sensing ports

Before you order

  • Confirm your appliance is a 40kW model from the Duo-tec, Platinum or Titanium ranges
  • Check the serial number suffix on the data badge against the fit list, as several models are split by serial ending
  • Cross-check the GC number on your boiler's data badge against the appliance listing
  • Verify the existing venturi part number before removal, where it is legible
