Worcester Bosch Oil Nozzle 0.35 x 80° S Type 87161060620

The Worcester Bosch 87161060620 is a Danfoss S type oil nozzle rated at 0.35 US gal/h with an 80° spray angle. It sits in the burner of Worcester Bosch oil-fired appliances, where pressurised oil is driven through the nozzle body and forced out of a fine orifice at high velocity. The resulting impact breaks the oil into a cloud of microscopic droplets, which is what allows the fuel to mix with air and burn cleanly.

Because the orifice governs both the volume of oil delivered and the shape of the spray pattern, the nozzle is a wear item that directly affects combustion quality.

• Smoke from the flue or visible sooting around the burner and heat exchanger
• Repeated burner lockouts, or the burner failing to establish a flame
• An unstable, pulsating or ragged flame rather than a steady one
• Combustion readings drifting out of range, such as rising CO or falling CO2
• A worn, blocked or damaged orifice found when the nozzle is inspected

• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Confirm the appliance model and serial number against the compatibility list before ordering.
• Match the flow rating and spray angle to the nozzle being removed, as both affect combustion setup.
• Note the alternative part number 1014821 when cross-referencing the original fitment.
