Delavan 00750-70W7 Oil Burner Nozzle 7.50 Gph 70 Degree

Product Description

The DELAVAN 00750-70W7 is an oil burner nozzle rated at 7.50 gallons per hour (GPH) with a 70-degree wide-angle spray pattern. It includes an integrated mesh strainer that filters fuel before atomization, helping maintain consistent combustion performance. This nozzle is installed in residential and light commercial oil-fired heating appliances, including forced-air furnaces and boilers. Licensed oil burner technicians and HVAC service professionals handle replacement as part of routine annual maintenance or combustion troubleshooting.

The 00750-70W7 is suited for oil-fired heating systems requiring a 7.50 GPH flow rate and a 70-degree wide spray angle. The wide-angle pattern is typically specified in applications where the combustion chamber geometry calls for a broader flame envelope. Always verify the OEM nozzle specification on the appliance nameplate or service manual before installing a replacement nozzle, as flow rate, spray angle, and pattern type must match the burner design exactly.

Key Features

• 7.50 GPH flow rate for precise fuel delivery to the combustion chamber
• 70-degree wide-angle spray pattern matched to broader combustion chamber designs
• Integrated mesh strainer filters particulates from fuel before atomization
• Solid-brass construction standard to DELAVAN oil burner nozzle series
• Drop-in replacement form factor for compatible oil burner assemblies

Compatibility

Designed as a direct-replacement oil burner nozzle for residential and light commercial oil-fired furnaces and boilers requiring a 7.50 GPH, 70-degree wide-angle nozzle. Confirm burner manufacturer specifications before installation.

Installation Notes

Oil burner nozzle replacement is performed by licensed heating technicians or qualified HVAC service professionals. Shut down the burner and allow all components to cool before service. Use a proper nozzle wrench to remove and seat the nozzle without distorting the adapter or nozzle body. After installation, a combustion analysis should be performed to verify CO2, stack temperature, and smoke number are within acceptable limits per the appliance manufacturer and applicable codes.
