What it is
The Baxi 5122464 is a pressure sensing venturi used in Baxi, Potterton and related system gas boilers. It sits in the air/gas path and provides the pressure signal the boiler uses to monitor combustion air flow. It is listed under gas boiler spares for the Megaflo, Promax and Gold system ranges.
Signs this part needs replacing
- Boiler locks out or fails to fire, with fan or air pressure related fault codes
- Combustion readings outside the expected range at the flue
- Whistling or unusual noise from the air/gas path
- Erratic flame picture or unstable burner operation
- Visible damage, blockage or debris in the venturi
Before you order
- Confirm your appliance model against the fit list above
- Check the serial number suffix where the fit line specifies one
- Compare the part number 5122464 with the marking on the component being removed
- Check the venturi is not obstructed before condemning it, as blockages can mimic a failed part
