Vokera Venturi 105932

The Vokera 105932 is a venturi used in Vokera Condexa PRO boilers. It forms part of the combustion air and gas mixing arrangement, drawing air through a narrowing section to create the pressure differential that the boiler's gas valve and fan control rely on. Correct venturi operation is essential to stable ignition and consistent combustion across the appliance's modulation range.

• The boiler fails to ignite or locks out repeatedly, particularly on start-up
• Combustion readings fall outside the expected range on flue gas analysis
• Unstable or rough flame, or a flame that will not hold at low modulation
• Sooting or discolouration around the burner or combustion chamber
• Whistling or unusual noise from the air and gas mixing assembly

• Confirm the appliance model and, where available, the serial number against the manufacturer's parts list
• Check the part number marked on the existing venturi matches 105932
• Inspect the surrounding air and gas pipework and seals, as disturbed joints may also need attention
• Verify the boiler has not been converted or modified in a way that changes the combustion components required
