Delavan 01100-90B7 Solid Cone Nozzle 11.00 Gph 90 Degree

Product Description

The DELAVAN 01100-90B7 is a solid cone oil burner nozzle rated at 11.00 gallons per hour (GPH) with a 90-degree spray angle. It is designed to atomize fuel oil inside residential and light commercial oil-fired heating equipment, delivering a consistent solid cone spray pattern to support stable combustion. The included mesh strainer helps filter particulates before they reach the nozzle orifice, protecting spray geometry and reducing nozzle fouling between service intervals. HVAC technicians and oil burner service professionals install this nozzle as a direct replacement during routine tune-ups and combustion analysis service calls.

This nozzle is suited for oil-fired furnaces, boilers, and water heaters that require an 11.00 GPH solid cone spray pattern at a 90-degree angle. The B spray designation indicates a specific hollow-to-solid cone classification used to match burner head geometry and combustion chamber dimensions. Selecting the correct GPH rating, spray angle, and pattern type is critical to achieving proper combustion efficiency and minimizing smoke and soot.

Key Features

• 11.00 GPH flow rate for medium-to-high output oil burner applications
• 90-degree spray angle matches a wide range of standard combustion chamber geometries
• Solid cone spray pattern (B designation) for uniform fuel distribution
• Integrated mesh strainer filters fuel before it reaches the orifice
• OEM-style replacement format for straightforward field swaps during annual service

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters requiring an 11.00 GPH, 90-degree, solid cone B-type nozzle.

Installation Notes

Oil burner nozzle replacement is performed by licensed HVAC technicians or qualified oil burner service technicians. Shut down the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the adapter or electrodes, and never reuse a removed nozzle. Verify GPH rating, spray angle, and spray pattern type against the appliance manufacturer specifications before installing a replacement.
