Delavan 175-80b1 Oil Burner Nozzle 1.75 Gph 80 Degree

Product Description

The DELAVAN 175-80b1 is a Type B solid cone oil burner nozzle rated at 1.75 gallons per hour (GPH) with an 80-degree spray angle. It meters and atomizes fuel oil into a fine, consistent spray pattern inside residential and light commercial oil-fired heating equipment. The solid cone pattern delivers uniform fuel distribution across the full spray envelope, which supports stable combustion and clean ignition. This nozzle is installed by licensed oil burner technicians as part of routine annual service or combustion tune-up procedures.

This nozzle is suited for oil-fired forced-air furnaces, boilers, and water heaters that require a solid cone spray pattern at a 1.75 GPH firing rate and an 80-degree angle. The Type B designation indicates a medium spray angle distribution appropriate for a wide range of standard retention-head and older style burner configurations. Technicians select this nozzle based on the appliance manufacturer's specified firing rate, spray pattern, and angle to match combustion chamber geometry.

Installation Notes

Oil burner nozzle service should be performed by a qualified oil burner technician. Shut down the burner and allow fuel lines to depressurize before removing the existing nozzle. Use an appropriate nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. After replacement, perform a combustion analysis to verify CO2, stack temperature, and smoke number meet appliance specifications.
