Delavan 75-80b1 Oil Burner Nozzle 0.75 Gph 80 Degree

Product Description

The DELAVAN 75-80b1 is a Type B solid cone oil burner nozzle rated at 0.75 gallons per hour (GPH) with an 80-degree spray angle. It meters and atomizes fuel oil into a consistent solid cone spray pattern, delivering a controlled flame shape inside the combustion chamber of an oil-fired heating appliance. The solid cone pattern distributes fuel evenly across the spray cross-section, which suits shorter combustion chambers where full flame fill is needed. This nozzle is installed by licensed oil burner technicians and HVAC service professionals during routine nozzle replacement or burner tune-up service.

This nozzle is suited for residential and light commercial oil-fired heating equipment, including forced-air oil furnaces and oil-fired boilers. The 0.75 GPH flow rate and 80-degree solid cone pattern are selected based on the burner manufacturer specifications and the heat output requirements of the appliance. Nozzle replacement is a standard part of annual oil burner maintenance. The correct nozzle type, flow rate, and angle must match the burner and appliance manufacturer specifications exactly.

Key Features

• 0.75 GPH flow rate for precise fuel metering matched to appliance heat output requirements
• 80-degree spray angle for wide pattern coverage in appropriate combustion chambers
• Type B solid cone spray pattern distributes fuel evenly across the full cone cross-section
• Standard nozzle form factor compatible with common oil burner nozzle assemblies
• Designed for annual replacement as part of routine oil burner preventive maintenance

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters that specify a 0.75 GPH, 80-degree, Type B solid cone nozzle per the appliance and burner manufacturer service documentation.

Installation Notes

Oil burner nozzle replacement should be performed by a qualified oil burner technician or licensed HVAC service professional. Shut down the burner and allow the system to cool before servicing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle to avoid damaging the nozzle adapter or electrodes. Always verify that the replacement nozzle flow rate, spray angle, and pattern type match the burner and appliance manufacturer specifications before starting the burner.
