Worcester Bosch Burner Nozzle 0.50 60 Degree ES 87161566730

The Worcester Bosch 87161566730 is a burner nozzle for oil-fired boilers. It sits at the burner head and atomises the oil supply into a fine, correctly shaped spray so the fuel mixes with air and burns cleanly inside the combustion chamber. The nozzle is a service item on Danesmoor FS and Greenstar Camray System External appliances, and its flow rate and spray angle must match the appliance it is fitted to.

• The burner lights but the flame is unstable, noisy or visibly the wrong shape
• Soot deposits build up on the combustion chamber, baffles or heat exchanger
• Combustion readings drift out of the expected CO2 or CO range at service
• The boiler locks out repeatedly or fails to establish a flame
• The nozzle body or its internal filter is blocked, worn or damaged on inspection

• Confirm the appliance model and serial number, and check the nozzle rating stamped on the existing nozzle matches the 0.50 60 degree ES specification before ordering
• Check the burner manufacturer's data for the appliance to confirm the correct nozzle for the commissioned output
• Inspect the nozzle seal and burner gaskets at the same time, as these are commonly disturbed during a nozzle change
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
