Delavan 33769-089 Variflo Nozzle 80 Degree 22 Gph

Product Description

The DELAVAN 33769-089 is a Variflo pressure atomizing nozzle designed for oil-fired burner applications. It produces a finely atomized spray pattern at an 80-degree angle and delivers a flow rate of 22 gallons per hour (GPH). Pressure atomizing nozzles like this one convert liquid fuel into a fine mist, enabling efficient combustion in residential and light commercial heating equipment. Installation and replacement are performed by licensed oil burner technicians as part of routine service or combustion tuning.

This nozzle is suited for use in oil-fired furnaces, boilers, and water heaters where a wide-angle spray pattern is required. The 80-degree spray angle is typically used in applications with shorter combustion chambers, where a broader flame pattern improves heat distribution and combustion efficiency. The 22 GPH flow rate corresponds to a specific firing rate matched to the burner and heat exchanger design of the equipment being serviced.

Key Features

• Variflo design allows variable flow characteristics to support stable atomization across a range of operating pressures
• 80-degree spray angle suits wide, shallow combustion chambers
• 22 GPH flow rate for matched firing rate applications
• Pressure atomizing design produces fine fuel mist for efficient combustion
• OEM-style replacement form factor for straightforward swap-out during annual service

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired burners requiring a Variflo-type pressure atomizing nozzle with an 80-degree spray angle and 22 GPH flow rate. Verify burner manufacturer specifications before installation to confirm correct nozzle type, angle, and flow rate.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil heat technicians. Shut down the burner and allow all components to cool before beginning service. Use a proper nozzle wrench to remove and install the nozzle without damaging the adapter or fuel line fittings. After installation, verify combustion performance with appropriate test equipment per local code and manufacturer guidelines.
