What it is

The Sime 6274128 is a 3.70 mm main burner nozzle for LPG (liquefied petroleum gas) boilers. It controls the flow of gas into the main burner, where it mixes with air for combustion. It is fitted across the Sime Murelle and Economy HE boiler families.

Signs this part needs replacing

  • The burner fails to light, or lights intermittently
  • A weak, uneven or yellow flame at the main burner
  • Sooting or black marks around the burner or heat exchanger
  • Combustion readings outside the expected range, including raised CO
  • Visible blockage, damage or wear at the nozzle orifice

Before you order

  • Confirm your appliance model against the fit list above.
  • Check the appliance is set up for LPG; this nozzle is not intended for natural gas.
  • Confirm the existing nozzle is marked 3.70 mm.
  • Have the appliance model and serial number to hand when checking the manufacturer's parts list.
