Alpha Burner Assembly 6.5631970

The Alpha burner assembly is the component that carries and distributes the gas/air mixture for combustion inside the boiler's heat exchanger. It is listed for the Alpha 240E, 240X, 240XE and 280E gas boiler range. The burner is a serviceable combustion part, replaced when flame quality or combustion readings fall outside acceptable limits.

• Yellow, lazy or lifting flame instead of a stable blue flame
• Sooting or blackening around the burner and heat exchanger
• Combustion readings (CO/CO₂ ratio) outside the manufacturer's tolerance
• Uneven flame pattern across the burner surface
• Repeated ignition or flame-failure faults traced to the burner

• Confirm the boiler model and, where shown, the GC number against the appliance data badge
• Check whether the appliance is the LPG or natural gas variant, as the listed fitment covers LPG models
• Compare the part number on the existing burner with 6.5631970 before ordering
• Combustion components should be fitted and commissioned by a competent gas engineer
