Delavan 100-80a1 Oil Burner Nozzle 1.0 Gph 80 Degree

Product Description

The DELAVAN 100-80a1 is a replacement oil burner nozzle rated at 1.0 gallons per hour (GPH) with an 80-degree spray angle and a Type A hollow cone pattern. It is designed for residential and light-commercial oil-fired heating systems where the original nozzle has worn or requires seasonal replacement. Licensed oil burner technicians and heating contractors install this nozzle as part of routine annual tune-ups or emergency service calls. Matching GPH rating, spray angle, and cone type to the original specification is critical for proper combustion efficiency and equipment safety.

This nozzle fits standard oil burner assemblies found in forced-air furnaces, boilers, and water heaters that fire on No. 2 fuel oil. It is sized for systems requiring a 1.0 GPH firing rate at a typical supply pressure of 100 psi. The 80-degree spray angle and Type A cone pattern suit a range of combustion chamber geometries commonly found in residential heating equipment. Always confirm the GPH, spray angle, and cone type stamped on the original nozzle before installing a replacement.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified heating contractor. Shut off fuel supply and power to the burner assembly before beginning service. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. Follow local and national fuel oil equipment codes for service procedures and startup verification.
