Delavan 00200-45a1 Oil Burner Nozzle 2.0 Gph 45 Degree

Product Description

The DELAVAN 00200-45a1 is a Type A hollow cone oil burner nozzle rated at 2.0 gallons per hour (GPH) with a 45-degree spray angle. It atomizes fuel oil into a fine, evenly distributed hollow cone pattern for efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone pattern delivers fuel to the outer edges of the flame envelope, making it well suited for burners that require a defined flame shape with good ignition characteristics. This nozzle is installed by licensed oil burner technicians and HVAC service professionals during routine nozzle replacement or burner tune-up service.

This nozzle is used in residential oil-fired forced-air furnaces, boilers, and water heaters equipped with pressure-atomizing gun-type burners. A 2.0 GPH flow rate at standard operating pressure suits mid-range firing rate applications. The 45-degree hollow cone spray pattern is specified for burner heads that call for a Type A designation, and selecting the correct pattern type is critical to achieving proper flame geometry and combustion efficiency.

Key Features

• 2.0 GPH flow rate for mid-range oil burner firing applications
• 45-degree spray angle matched to burner head geometry requirements
• Type A hollow cone atomization pattern for defined outer-edge fuel distribution
• Pressure-atomizing design compatible with standard gun-type oil burner assemblies
• Precision-machined orifice for consistent flow rate and repeatable combustion performance

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial pressure-atomizing gun-type oil burners specifying a 2.0 GPH, 45-degree, Type A hollow cone nozzle.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the combustion chamber to cool completely before servicing. Use a proper nozzle wrench to remove and install the nozzle without damaging the adapter or electrodes, and verify the firing rate and spray pattern designation match the burner manufacturer specifications before startup. Annual nozzle replacement is standard practice during oil burner tune-up service.
