Delavan 01200-45A7 Oil Burner Nozzle 12 Gph 45 Degree

Product Description

The DELAVAN 01200-45A7 is a hollow-cone Type A oil burner nozzle rated at 12.00 GPH flow rate with a 45-degree spray angle. It features a brass body and steel orifice disc construction, rated for operation at 100 psi and up to 80 degrees F. The nozzle uses a sintered filter and produces a hollow-cone spray pattern that concentrates droplet distribution on the outer edge of the cone. This design supports reliable ignition and low-noise combustion in oil-fired heating systems. HVAC and oil burner service technicians install this nozzle as part of routine burner maintenance and combustion tuning service calls.

The 01200-45A7 is designed for residential oil-fired heating applications. Hollow-cone Type A nozzles are suited for burners with a hollow-cone air pattern and are appropriate for throughputs up to 2.00 GPH on smaller systems, while this 12.00 GPH model serves higher-demand residential oil burner configurations. It is a standard replacement nozzle used during annual tune-ups, burner head service, or combustion efficiency diagnostics.

Installation Notes

Oil burner nozzle replacement is performed by licensed HVAC technicians or qualified oil burner service professionals. Always shut down the burner and allow the system to cool before removing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the nozzle adapter or electrode assembly. Verify combustion performance with appropriate test equipment after installation per applicable service standards.
