Worcester Bosch Burner Nozzle 0.55 x 60 Deg 87161061540

The Worcester Bosch 87161061540 is a Danfoss-pattern burner nozzle rated at 0.55 with a 60 degree spray angle, supplied in ES form. It sits at the burner head of an oil-fired appliance and controls the flow and atomisation of fuel as it is delivered into the combustion chamber. The nozzle is a service item on the Danesmoor FS range of floor-standing oil boilers, where the spray pattern and flow rate directly affect combustion quality, flame stability and flue gas readings.

• Soot deposits around the burner head, baffles or flue ways, indicating poor atomisation
• An unstable or pulsating flame, or a flame that lifts away from the burner head
• Rising CO readings or smoke spot test results that cannot be brought back into range by adjustment alone
• Difficulty establishing or holding a reliable flame at start-up
• A nozzle that has been in service through several annual services and is due on the maintenance schedule

• Confirm the appliance model and serial number against the compatibility list, as nozzle ratings differ between Danesmoor variants
• Check the rating and spray angle stamped on the existing nozzle match 0.55 and 60 degrees before fitting
• Note the alternative part number 1021004 when cross-referencing older documentation
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
