Delavan 00100-90b1 Oil Nozzle 1.00 Gph 90 Degree Solid

Product Description

The DELAVAN 00100-90b1 is a solid-spray oil burner nozzle rated at 1.00 gallon per hour (GPH) with a 90-degree spray angle. It atomizes fuel oil into a fine, consistent mist for combustion inside residential and light-commercial oil-fired heating equipment. The solid spray pattern delivers a dense, even distribution across the combustion chamber, which supports stable ignition and clean burn characteristics. Licensed oil burner technicians and HVAC service professionals install and replace this nozzle as part of routine annual maintenance or when combustion efficiency drops.

This nozzle is suited for oil-fired forced-air furnaces, boilers, and water heaters that require a 1.00 GPH flow rate with a 90-degree solid spray pattern. It is a direct-fit replacement in systems designed around Delavan B-series nozzle specifications. The 90-degree angle is typically selected for shorter, wider combustion chambers where a broader spray pattern is required to achieve proper flame geometry and complete combustion.

Key Features

• 1.00 GPH flow rate for precise fuel delivery at rated firing conditions
• 90-degree spray angle matched to wide or short combustion chamber geometry
• Solid spray pattern for dense, centered fuel distribution and stable ignition
• B-series Delavan nozzle construction for consistent atomization
• Drop-in replacement for annual oil burner tune-up service

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters requiring a 1.00 GPH, 90-degree solid-spray nozzle at the burner head.

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 system to cool before servicing the nozzle assembly. Use a proper nozzle wrench to remove and install the nozzle without damaging the electrodes or nozzle adapter. Always verify firing rate, spray angle, and spray pattern match the appliance manufacturer's specifications before returning the system to service.
