What it is
The INJECTOR 3.85MM is a Broag pilot injector, part number 53943, used in the pilot burner assembly of Broag commercial gas boilers. It meters gas flow to the pilot burner, providing the stable flame that ignites the main burner. It is a serviceable component within the boiler's gas train and is replaced as part of pilot fault diagnosis and repair.
Signs this part needs replacing
- The pilot will not light, or lights and extinguishes shortly after ignition
- A weak, lazy or unstable pilot flame that fails to hold on the flame sensor
- Visible blockage, debris or corrosion in the injector orifice
- Repeated lockouts traced to pilot failure rather than the ignition electrode or gas valve
- Soot or discolouration around the pilot assembly indicating poor combustion at the pilot
Before you order
- Confirm the boiler model is Broag Commercial GAS 450S
- Check the existing injector marking to verify the 3.85 mm size is correct for the appliance
- Inspect the pilot assembly, ignition electrode, lead and flame sensor before replacing the injector alone
- Confirm the boiler gas type and any site-specific commissioning requirements before working on the gas train
