Delavan 00550-60w7 Oil Burner Nozzle 5.50 Gph 60 Degree

Product Description

The DELAVAN 00550-60w7 is a Type SS semi-solid cone oil burner nozzle rated at 5.50 gallons per hour (GPH) with a 60-degree spray angle. This nozzle atomizes fuel oil at the burner head, producing a semi-solid cone spray pattern that suits specific combustion chamber geometries found in residential and light commercial oil-fired heating equipment. It is sized for higher-output burner applications and is installed by licensed oil burner technicians or HVAC professionals during routine nozzle replacement or burner tune-up service. The semi-solid cone pattern delivers fuel distribution between a hollow and solid cone, making it appropriate for combustion chambers that require a denser center flame pattern.

This nozzle is used in oil-fired forced-air furnaces, boilers, and water heaters where the burner assembly specifies a 5.50 GPH flow rate and a 60-degree spray angle. It is a standard replacement component serviced during annual oil burner maintenance, nozzle changeout, or after a fuel delivery interruption. Technicians select this nozzle based on the burner manufacturer's nozzle specification label or equipment documentation.

Key Features

• 5.50 GPH flow rate for higher-output oil burner applications
• 60-degree spray angle matched to specific combustion chamber depths
• Type SS semi-solid cone pattern for dense center fuel distribution
• Standard nozzle form factor for drop-in replacement service
• Lightweight at 0.75 pounds for easy field handling

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired burners specifying a 5.50 GPH, 60-degree, Type SS semi-solid cone nozzle. Consult the burner nameplate or equipment service manual to confirm nozzle specification before installation.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil burner technicians or licensed HVAC service professionals. Shut off the burner and allow the system to cool completely before accessing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle to avoid damaging the electrode assembly or nozzle adapter. After replacement, perform a combustion analysis to verify proper air-fuel ratio and flame quality before returning the system to service.
