What it is
The injector manifold is a gas-carrying burner component used on Alpha 280 series boilers. It holds and feeds the burner injectors, delivering gas at the correct rate to each burner port. It is listed by Alpha under part number 6.5633140.
Signs this part needs replacing
- Burner flames that are uneven, lifting or yellow rather than a steady blue
- Soot deposits or discolouration around the burner ports
- Visible damage, corrosion or blockage at the manifold or injector orifices
- Poor combustion readings that cannot be corrected by servicing or gas pressure adjustment
- Gas smell or leakage traced to the manifold or injector joints
Before you order
- Confirm the boiler model and, where shown, the GC number against the fitment list above
- Check whether the appliance is the LPG (280E) or natural gas (280P) variant, as the injectors differ
- Inspect the existing manifold and injectors for damage before removal so the correct assembly is ordered
- Gas-carrying components must be fitted and commissioned by a competent, registered engineer
