Delavan 00275-90W7 Oil Burner Nozzle 2.75 Gph 90 Degree

Product Description

The DELAVAN 00275-90W7 is a Type W all-purpose oil burner nozzle rated at 2.75 gallons per hour (GPH) with a 90-degree spray angle. Constructed with a brass body and steel orifice disc, it delivers a spray pattern that falls between a true hollow cone and a true solid cone. This intermediate pattern makes it adaptable across a wide range of residential oil burner configurations. The nozzle is rated for operation at 100 psi and up to 80 degrees F. It is installed by licensed oil burner technicians as part of routine burner service or combustion tune-up work.

This nozzle is designed for residential oil-fired heating applications. Type W nozzles are a practical choice for service techs who need a dependable all-purpose option across flow rates from 0.40 to 8.00 GPH, regardless of the burner air pattern. At lower flow rates, the spray pattern trends toward hollow cone behavior. The 00275-90W7 fits standard residential oil burner nozzle assemblies and is a common stocking item for heating contractors servicing forced-air or hydronic oil heating systems.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil burner service technicians. Shut down the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes. Verify fuel supply pressure at the pump matches the nozzle pressure rating before firing the system, and perform a combustion analysis after installation to confirm proper air-fuel setup.
