What it is
This is a 3.40 mm natural gas nozzle manufactured by Sime. It acts as the main burner injector on Sime Superior 50 MKII boilers, controlling the flow of gas into the burner for combustion.
Signs this part needs replacing
- Burner flame is yellow or unstable rather than a steady blue
- Soot deposits or blackening around the burner
- Boiler fails to light or lights intermittently
- Combustion faults or repeated lockouts
Before you order
- Confirm the boiler model is the Sime Superior 50 MKII
- Check the appliance is set up for natural gas, not LPG
- Verify the existing nozzle diameter is 3.40 mm
- Consult the manufacturer's parts list if unsure
