What it is

The Baxi 5122462 is a 4.5mm gas injector fitted in the burner assembly of Baxi Megaflo 15 and Potterton Promax 15 system boilers. It meters gas into the burner to establish the correct combustion rate for the appliance. It is listed as a burner spare for the System 15 range.

Signs this part needs replacing

  • The burner fails to light, or lights intermittently
  • A weak, uneven or yellow flame at the burner
  • Sooting or black marks around the burner area
  • The measured gas rate falls outside the figure on the appliance data badge
  • Visible blockage, damage or wear at the injector orifice

Before you order

  • Confirm the appliance is a Baxi Megaflo 15 or Potterton Promax 15 system boiler
  • Check the serial number suffix on the data badge where the fit list specifies AC, BC, CC or DC
  • Confirm the existing injector is marked 4.5mm
  • Check the GC number on the appliance data badge against the model listed
