Delavan 135-80b1 Oil Burner Nozzle 1.35 Gph 80 Degree

Product Description

The DELAVAN 135-80b1 is a Type B solid cone oil burner nozzle rated at 1.35 gallons per hour (GPH) with an 80-degree spray angle. It meters and atomizes fuel oil into the combustion chamber of a residential or light commercial oil-fired burner, producing a tight, solid cone spray pattern suited for shorter, wider flame geometries. Licensed oil burner technicians install this nozzle as part of routine annual maintenance or when replacing a worn or improperly sized tip. The solid cone pattern distributes fuel evenly across the full cone, making it appropriate for pot-type and pressure-atomizing burners that require complete coverage of the combustion zone.

This nozzle is commonly installed in residential oil-fired forced-air furnaces, oil boilers, and water heaters that use a pressure-atomizing gun-type burner. The 80-degree angle is a wide-angle configuration used when the combustion chamber is relatively short and broad. The 1.35 GPH flow rate corresponds to a specific heat input and must match the appliance manufacturer's nozzle specification to maintain proper combustion efficiency and BTU output. Always verify the required GPH, angle, and pattern type on the appliance data plate or service manual before installation.

Key Features

• 1.35 GPH flow rate for precise fuel metering at rated pump pressure
• 80-degree wide spray angle suited for short, broad combustion chambers
• Type B solid cone pattern provides full, even fuel distribution across the spray zone
• Designed for use with No. 1 and No. 2 fuel oil in standard residential and light commercial oil burners
• Replacement nozzle for annual oil burner tune-up and maintenance service

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial pressure-atomizing oil burners requiring a 1.35 GPH, 80-degree, solid cone Type B nozzle configuration.

Installation Notes

Oil burner nozzles are installed by licensed oil burner technicians in jurisdictions that require it. Before servicing, shut off power to the burner at the service switch and close the fuel supply valve. The nozzle must be replaced using the correct wrench to avoid damaging the nozzle adapter or electrodes. Always verify GPH, spray angle, and spray pattern against the appliance rating plate before installing a replacement nozzle, and perform a combustion analysis after startup to confirm proper operation.
