Worcester Bosch Burner Assembly NG 87161426520

The Worcester Bosch 87161426520 is a natural gas burner assembly used in the 28i RSF range of Worcester Bosch appliances. It sits in the combustion chamber and distributes the gas/air mixture across the burner head, where it is ignited to produce the flame that heats the primary water circuit. As a gas-carrying component it is central to clean, stable combustion and to the appliance meeting its rated heat output.

• Repeated ignition lockouts or flame failure faults after the burner has been called for heat
• A weak, uneven or partially established flame across the burner head
• Yellow, lazy or sooting flame where combustion was previously clean and blue
• Visible corrosion, distortion or cracking on the burner body or its ports
• Sooting deposits on the heat exchanger or combustion chamber surfaces

• Confirm the appliance model and GC number against the compatibility list, as burner assemblies differ between variants and gas types
• Check the existing part number on the appliance and cross-reference it with 1018397 before ordering
• Inspect the burner gasket and seal during removal and replace if it is compressed, brittle or damaged
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
