What it is

The Baxi 7212978 is a venturi used on Baxi Ecoblue System 15 kW and 18 kW gas boilers, including the ErP versions. It forms part of the appliance's air and gas supply arrangement, where the venturi creates the pressure differential used for combustion control. It is a serviceable component and is replaced as a single item.

Signs this part needs replacing

  • The boiler locks out or fails to establish a flame on start-up
  • Repeated fan or air pressure related fault codes
  • Whistling or unusual noise from the air and gas intake
  • Poor combustion, sooting or an unstable flame
  • Intermittent operation once the appliance has warmed up

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check that the part number on the existing venturi matches 7212978
  • Confirm the boiler is a 15 kW or 18 kW Ecoblue System model
  • Any work on the air and gas path must be carried out by a Gas Safe registered engineer
