Delavan 00275-80W7 Oil Burner Nozzle 2.75 Gph 80 Degree

Product Description

The DELAVAN 00275-80W7 is an oil burner nozzle rated at 2.75 gallons per hour (GPH) with an 80-degree spray angle and a semisolid spray pattern. Oil burner nozzles atomize fuel oil into a fine mist before ignition, directly affecting combustion efficiency, flame shape, and heat output. This nozzle is installed by HVAC technicians and oil burner service professionals during routine maintenance, nozzle replacement service calls, or burner tune-ups. The semisolid spray pattern delivers a cone that is denser at the center than the outer edges, making it well suited for burner heads that require a tighter flame pattern.

This nozzle is used in residential and light commercial oil-fired heating equipment including forced-air furnaces, boilers, and water heaters equipped with pressure-atomizing oil burners. Nozzle replacement is a standard part of annual oil heat service. Selecting the correct GPH rating, spray angle, and spray pattern is critical to matching the original equipment specifications and achieving proper combustion. The 00275-80W7 is designed for installations where the burner manufacturer specifies a 2.75 GPH, 80-degree semisolid nozzle.

Key Features

• 2.75 GPH flow rate for precise fuel delivery matching original burner specifications
• 80-degree spray angle suited for burner heads requiring a wider flame cone
• Semisolid spray pattern provides a center-dense fuel distribution for stable combustion
• Standard pressure-atomizing design compatible with conventional oil burner assemblies
• Direct replacement format for routine annual oil burner service

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial pressure-atomizing oil burners requiring a 2.75 GPH, 80-degree semisolid spray nozzle. Always verify the burner manufacturer's nozzle specification before installation.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil heat technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to remove and seat the nozzle without damaging the nozzle adapter or electrode assembly. After replacement, verify combustion performance with a combustion analyzer to confirm CO2, smoke number, and stack temperature are within acceptable limits.
