What it is

The Sime main burner nozzle NP75 with M6 thread is a gas injector for the main burner of Sime LPG boilers. It controls the flow of gas into the burner so the correct air/gas mixture is maintained for combustion. The nozzle is listed for appliances across the Sime Format, Friendly Format, Murelle, Metro, Open, Planet and Aquaquick ranges.

Signs this part needs replacing

  • The burner fails to light, or lights and then drops out.
  • The flame is weak, uneven or noticeably smaller than expected.
  • The flame burns yellow or lifts off the burner instead of sitting steady and blue.
  • Soot deposits appear around the burner or on the heat exchanger.
  • Combustion readings drift outside the expected range on an LPG appliance.

Before you order

  • Check the appliance model against the fits list above.
  • Confirm the boiler is running on LPG (GPL), not natural gas.
  • Check the existing nozzle is marked NP75 with an M6 thread.
  • Have the appliance model or GC number to hand when checking compatibility.
